-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,

-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-

-Creative Commons Corporation ("Creative Commons") is not a law firm and
-does not provide legal services or legal advice. Distribution of
-Creative Commons public licenses does not create a lawyer-client or

-
-Using Creative Commons Public Licenses
-
-Creative Commons public licenses provide a standard set of terms and
-conditions that creators and other rights holders may use to share
-original works of authorship and other material subject to copyright
-and certain other rights specified in the public license below. The
-following considerations are for informational purposes only, are not
-exhaustive, and do not form part of our licenses.
-
-     Considerations for licensors: Our public licenses are
-     intended for use by those authorized to give the public
-     permission to use material in ways otherwise restricted by
-     copyright and certain other rights. Our licenses are
-     irrevocable. Licensors should read and understand the terms
-     and conditions of the license they choose before applying it.
-     Licensors should also secure all rights necessary before
-     applying our licenses so that the public can reuse the
-     material as expected. Licensors should clearly mark any
-     material not subject to the license. This includes other CC-
-     licensed material, or material used under an exception or
-     limitation to copyright. More considerations for licensors:
-    wiki.creativecommons.org/Considerations_for_licensors
-
-     Considerations for the public: By using one of our public
-     licenses, a licensor grants the public permission to use the
-     licensed material under specified terms and conditions. If
-     the licensor's permission is not necessary for any reason--for
-     example, because of any applicable exception or limitation to
-     copyright--then that use is not regulated by the license. Our
-     licenses grant only permissions under copyright and certain
-     other rights that a licensor has authority to grant. Use of
-     the licensed material may still be restricted for other
-     reasons, including because others have copyright or other
-     rights in the material. A licensor may make special requests,
-     such as asking that all changes be marked or described.
-     Although not required by our licenses, you are encouraged to
-     respect those requests where reasonable. More considerations
-     for the public:

-Creative Commons Attribution 4.0 International Public License
-
-By exercising the Licensed Rights (defined below), You accept and agree
-to be bound by the terms and conditions of this Creative Commons
-Attribution 4.0 International Public License ("Public License"). To the
-extent this Public License may be interpreted as a contract, You are
-granted the Licensed Rights in consideration of Your acceptance of
-these terms and conditions, and the Licensor grants You such rights in
-consideration of benefits the Licensor receives from making the
-Licensed Material available under these terms and conditions.
-
-
-Section 1 -- Definitions.
-
-  a. Adapted Material means material subject to Copyright and Similar
-     Rights that is derived from or based upon the Licensed Material
-     and in which the Licensed Material is translated, altered,
-     arranged, transformed, or otherwise modified in a manner requiring
-     permission under the Copyright and Similar Rights held by the
-     Licensor. For purposes of this Public License, where the Licensed
-     Material is a musical work, performance, or sound recording,
-     Adapted Material is always produced where the Licensed Material is
-     synched in timed relation with a moving image.
-
-  b. Adapter's License means the license You apply to Your Copyright
-     and Similar Rights in Your contributions to Adapted Material in
-     accordance with the terms and conditions of this Public License.
-
-  c. Copyright and Similar Rights means copyright and/or similar rights
-     closely related to copyright including, without limitation,
-     performance, broadcast, sound recording, and Sui Generis Database
-     Rights, without regard to how the rights are labeled or
-     categorized. For purposes of this Public License, the rights
-     specified in Section 2(b)(1)-(2) are not Copyright and Similar
-     Rights.
-
-  d. Effective Technological Measures means those measures that, in the
-     absence of proper authority, may not be circumvented under laws
-     fulfilling obligations under Article 11 of the WIPO Copyright
-     Treaty adopted on December 20, 1996, and/or similar international
-     agreements.
-
-  e. Exceptions and Limitations means fair use, fair dealing, and/or
-     any other exception or limitation to Copyright and Similar Rights
-     that applies to Your use of the Licensed Material.
-
-  f. Licensed Material means the artistic or literary work, database,
-     or other material to which the Licensor applied this Public
-     License.
-
-  g. Licensed Rights means the rights granted to You subject to the
-     terms and conditions of this Public License, which are limited to
-     all Copyright and Similar Rights that apply to Your use of the
-     Licensed Material and that the Licensor has authority to license.
-
-  h. Licensor means the individual(s) or entity(ies) granting rights
-     under this Public License.
-
-  i. Share means to provide material to the public by any means or
-     process that requires permission under the Licensed Rights, such
-     as reproduction, public display, public performance, distribution,
-     dissemination, communication, or importation, and to make material
-     available to the public including in ways that members of the
-     public may access the material from a place and at a time
-     individually chosen by them.
-
-  j. Sui Generis Database Rights means rights other than copyright
-     resulting from Directive 96/9/EC of the European Parliament and of
-     the Council of 11 March 1996 on the legal protection of databases,
-     as amended and/or succeeded, as well as other essentially
-     equivalent rights anywhere in the world.
-
-  k. You means the individual or entity exercising the Licensed Rights
-     under this Public License. Your has a corresponding meaning.
-
-
-Section 2 -- Scope.
-
-  a. License grant.
-
-       1. Subject to the terms and conditions of this Public License,
-          the Licensor hereby grants You a worldwide, royalty-free,
-          non-sublicensable, non-exclusive, irrevocable license to
-          exercise the Licensed Rights in the Licensed Material to:
-
-            a. reproduce and Share the Licensed Material, in whole or
-               in part; and
-
-            b. produce, reproduce, and Share Adapted Material.
-
-       2. Exceptions and Limitations. For the avoidance of doubt, where
-          Exceptions and Limitations apply to Your use, this Public
-          License does not apply, and You do not need to comply with
-          its terms and conditions.
-
-       3. Term. The term of this Public License is specified in Section
-          6(a).
-
-       4. Media and formats; technical modifications allowed. The
-          Licensor authorizes You to exercise the Licensed Rights in
-          all media and formats whether now known or hereafter created,
-          and to make technical modifications necessary to do so. The
-          Licensor waives and/or agrees not to assert any right or
-          authority to forbid You from making technical modifications
-          necessary to exercise the Licensed Rights, including
-          technical modifications necessary to circumvent Effective
-          Technological Measures. For purposes of this Public License,
-          simply making modifications authorized by this Section 2(a)
-          (4) never produces Adapted Material.
-
-       5. Downstream recipients.
-
-            a. Offer from the Licensor -- Licensed Material. Every
-               recipient of the Licensed Material automatically
-               receives an offer from the Licensor to exercise the
-               Licensed Rights under the terms and conditions of this
-               Public License.
-
-            b. No downstream restrictions. You may not offer or impose
-               any additional or different terms or conditions on, or
-               apply any Effective Technological Measures to, the
-               Licensed Material if doing so restricts exercise of the
-               Licensed Rights by any recipient of the Licensed
-               Material.
-
-       6. No endorsement. Nothing in this Public License constitutes or
-          may be construed as permission to assert or imply that You
-          are, or that Your use of the Licensed Material is, connected
-          with, or sponsored, endorsed, or granted official status by,
-          the Licensor or others designated to receive attribution as
-          provided in Section 3(a)(1)(A)(i).
-
-  b. Other rights.
-
-       1. Moral rights, such as the right of integrity, are not
-          licensed under this Public License, nor are publicity,
-          privacy, and/or other similar personality rights; however, to
-          the extent possible, the Licensor waives and/or agrees not to
-          assert any such rights held by the Licensor to the limited
-          extent necessary to allow You to exercise the Licensed
-          Rights, but not otherwise.
-
-       2. Patent and trademark rights are not licensed under this
-          Public License.
-
-       3. To the extent possible, the Licensor waives any right to
-          collect royalties from You for the exercise of the Licensed
-          Rights, whether directly or through a collecting society
-          under any voluntary or waivable statutory or compulsory
-          licensing scheme. In all other cases the Licensor expressly
-          reserves any right to collect such royalties.
-
-
-Section 3 -- License Conditions.
-
-Your exercise of the Licensed Rights is expressly made subject to the
-following conditions.
-
-  a. Attribution.
-
-       1. If You Share the Licensed Material (including in modified
-          form), You must:
-
-            a. retain the following if it is supplied by the Licensor
-               with the Licensed Material:
-
-                 i. identification of the creator(s) of the Licensed
-                    Material and any others designated to receive
-                    attribution, in any reasonable manner requested by
-                    the Licensor (including by pseudonym if

-          reasonably practicable.
-
-       4. If You Share Adapted Material You produce, the Adapter's
-          License You apply must not prevent recipients of the Adapted
-          Material from complying with this Public License.
-
-
-Section 4 -- Sui Generis Database Rights.
-
-Where the Licensed Rights include Sui Generis Database Rights that
-apply to Your use of the Licensed Material:
-
-  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
-     to extract, reuse, reproduce, and Share all or a substantial
-     portion of the contents of the database;
-
-  b. if You include all or a substantial portion of the database
-     contents in a database in which You have Sui Generis Database
-     Rights, then the database in which You have Sui Generis Database
-     Rights (but not its individual contents) is Adapted Material; and
-
-  c. You must comply with the conditions in Section 3(a) if You Share
-     all or a substantial portion of the contents of the database.
-
-For the avoidance of doubt, this Section 4 supplements and does not
-replace Your obligations under this Public License where the Licensed
-Rights include other Copyright and Similar Rights.
-
-
-Section 5 -- Disclaimer of Warranties and Limitation of Liability.
-
-  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
-     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
-     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
-     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
-     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
-     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
-     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
-     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
-     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
-     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
-
-  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
-     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
-     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
-     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
-     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
-     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
-     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
-     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
-     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
-
-  c. The disclaimer of warranties and limitation of liability provided
-     above shall be interpreted in a manner that, to the extent
-     possible, most closely approximates an absolute disclaimer and
-     waiver of all liability.
-
-
-Section 6 -- Term and Termination.
-
-  a. This Public License applies for the term of the Copyright and
-     Similar Rights licensed here. However, if You fail to comply with
-     this Public License, then Your rights under this Public License
-     terminate automatically.
-
-  b. Where Your right to use the Licensed Material has terminated under
-     Section 6(a), it reinstates:
-
-       1. automatically as of the date the violation is cured, provided
-          it is cured within 30 days of Your discovery of the
-          violation; or
-
-       2. upon express reinstatement by the Licensor.
-
-     For the avoidance of doubt, this Section 6(b) does not affect any
-     right the Licensor may have to seek remedies for Your violations
-     of this Public License.
-
-  c. For the avoidance of doubt, the Licensor may also offer the
-     Licensed Material under separate terms or conditions or stop
-     distributing the Licensed Material at any time; however, doing so
-     will not terminate this Public License.
-
-  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
-     License.
-
-
-Section 7 -- Other Terms and Conditions.
-
-  a. The Licensor shall not be bound by any additional or different
-     terms or conditions communicated by You unless expressly agreed.
-
-  b. Any arrangements, understandings, or agreements regarding the
-     Licensed Material not stated herein are separate from and
-     independent of the terms and conditions of this Public License.
-
-
-Section 8 -- Interpretation.
-
-  a. For the avoidance of doubt, this Public License does not, and
-     shall not be interpreted to, reduce, limit, restrict, or impose
-     conditions on any use of the Licensed Material that could lawfully
-     be made without permission under this Public License.
-
-  b. To the extent possible, if any provision of this Public License is
-     deemed unenforceable, it shall be automatically reformed to the
-     minimum extent necessary to make it enforceable. If the provision
-     cannot be reformed, it shall be severed from this Public License
-     without affecting the enforceability of the remaining terms and
-     conditions.
-
-  c. No term or condition of this Public License will be waived and no
-     failure to comply consented to unless expressly agreed to by the
-     Licensor.
-
-  d. Nothing in this Public License constitutes or may be interpreted
-     as a limitation upon, or waiver of, any privileges and immunities
-     that apply to the Licensor or You, including from the legal
-     processes of any jurisdiction or authority.

-[[intro]]
-== Introduction
-
-This README describes how to build the Vulkan API specification, reference
-pages, and/or other related targets.
-
-It documents how to set up your build environment, build steps and targets,
-and contains some troubleshooting advice.
-
-[[building]]
-== Building The Spec
-
-First, clone the Khronos Github repository containing the Vulkan
-specification to your local Linux, Windows, or Mac PC.
-The repository is located at https://github.com/KhronosGroup/Vulkan-Docs/.
-
-Next, install all the necessary build tools (see <<depends,Software
-Dependencies>> below).
-If you are using the <<depends-docker, Khronos-Provided Docker Image>>,
-which we strongly recommend, then one way to build using the image (assuming
-a Linux docker host) is:
-
-    $ docker run --user `id -u`:`id -g` -it --rm \
-      -v <vulkan-path>:/vulkan \
-      khronosgroup/docker-images:asciidoctor-spec /bin/bash
-
-where <vulkan-path> is the path to the cloned repository. This runs the
-image with the cloned repository under /vulkan and accesses it as a
-specified user (set to your own user and group ID above), so that it doesn't
-get filled with files owned by another user.
-
-Then in the running image,
-
-    $ cd /vulkan
-    $ ./makeSpec -spec core html
-
-which builds an HTML5 specification output for the core Vulkan 1.2
-specification, with no extensions included, or
-
-    $ ./makeSpec -spec all all
-
-which builds the spec targets `html`, `pdf`, `styleguide`, `registry`,
-`manhtmlpages`, and `allchecks`, with *all* registered extensions included.
-
-There are many other ways of using the image, including inside a Continuous
-Integration pipeline; locally with persistent Docker volume storage of the
-repository; and so on.
-
-If you are not using our Docker image to build with, and you have a
-<<depends-nondocker, Non-Docker Build Environment>> with the entire
-toolchain installed, you can go to <vulkan-path> and invoke the same `make`
-commands there.
-
-[NOTE]
-.Note
-====
-  * While it's possible to invoke `make` directly, this is rarely
-    appropriate or useful.
-    Usually dozens to hundreds of build options must be set to specify the
-    desired set of extensions to include in the specification.
-    The `makeSpec` python script, which is discussed in more detail
-    <<building-extensions, below>>, simplifies this process for common
-    cases.
-  * The `all` target takes a long time to run, and generates outputs that
-    are irrelevant for most users.
-    The `html` target just generates the HTML output, which is often all
-    that's needed for spec bugfixes not involving extensions.
-  * The default `make` options build a Vulkan 1.2 specification with no
-    optional extensions.
-  * The `validusage` target is not built as part of the `all` target, due to
-    it needing to be built with all extensions enabled (`-spec all`).
-    Building the `validusage` target will fail otherwise.
-====
-
-These targets generate a variety of output documents in the directory
-specified by the Makefile variable `$(OUTDIR)` (by default, `out/`).
-The checked-in file `out/index.html` links to all these
-targets, or they can individually be found as follows:
-
-Vulkan Specification::
-  * `html` -- Single-file HTML5 in `$(OUTDIR)/html/vkspec.html`, and KaTeX
-    dependency in $(OUTDIR)/katex
-  * `chunked` -- Chunked HTML5 in `$(OUTDIR)/html/chap?.html`
-  * `pdf` -- PDF in `$(OUTDIR)/pdf/vkspec.pdf`
-"`styleguide`" (Vulkan Documentation and Extensions: Procedures and Conventions)::
-  * `styleguide` -- Single-file HTML5 in `$(OUTDIR)/styleguide.html`
-XML Registry schema document::
-  * `registry` -- Single-file HTML5 in `$(OUTDIR)/registry.html`
-<<building-diff,Diff spec>>::
-  * `diff_html` -- Single-file HTML5 in `$(OUTDIR)/html/diff.html`
-<<refpages,Reference pages>>::
-  * `manhtmlpages` -- File-per-entry-point HTML in `$(OUTDIR)/man/html/*`.
-    Must be built with all extensions enabled (using `makeSpec -spec all`).
-<<validation-scripts,Validator output>>::
-  * None at present. The `allchecks` target writes to standard output unless
-    the underlying script is given additional options.
-Valid usage database::
-  * `validusage` - json database of all valid usage statements in the
-     specification. Must be built with `./makeAllExts` (for now).
-     Output in `$(OUTDIR)/validation/validusage.json`.
-     A validated schema for the output of this is stored in
-     `$(CURDIR)/config/vu-to-json/vu_schema.json`
-
-Once you have the basic build working, an appropriate parallelization
-option, such as `-j 8`, should significantly speed up the reference page
-builds.
-
-If you encounter problems refer to the <<troubleshooting>> section.
-
-
-[[building-versions]]
-=== Building Specifications For Different API Versions
-
-The `Makefile` defaults to building a Vulkan 1.2 specification.
-This is controlled by Asciidoctor attributes passed in the Makefile variable
-`$(VERSIONS)`
-To instead build a Vulkan 1.1 specification, pass
-
-----
-VERSIONS="VK_VERSION_1_0 VK_VERSION_1_1"
-----
-
-on the `makeSpec` command line.
-
-
-[[building-extensions]]
-=== Building With Extensions Included
-
-Extensions are defined in the same source as the core Specification, but
-are only conditionally included in the output.
-http://asciidoctor.org/docs/user-manual/#attributes[Asciidoctor attributes]
-of the same name as the extension are used to define whether the extension
-is included or not -- defining such an attribute will cause the output to
-include the text for that extension.
-
-When building the specification, the extensions included are those specified
-as a space-separated list of extension names (e.g. `VK_KHR_surface`) in the
-Makefile variable `$(EXTENSIONS)`, usually set on the make command line.
-When changing the list of extensions, it is critical to remove all generated
-files using the `clean_generated` Makefile target, as the contents of
-generated files depends on `$(EXTENSIONS)`.
-
-The `makeSpec` wrapper script can clean generated files and then build one
-or more specification targets for a set of explicitly specified extensions,
-including all implicit extension dependencies of that set.
-It accepts these options:
-
-  * -clean - remove generated targets before building
-  * -v - print actions as well as executing them
-  * -n - print actions without executing them
-  * -genpath *path* - specify path to generated files (default `gen`)
-  * -spec *type* - build with sepcified sets of extensions.
-    *type* may be
-  ** *core* - no extensions added (default if not specified)
-  ** *khr* - all KHR extensions added
-  ** *all* - all registered extensions added
-  * -extension *extname* - build with specified extension included,
-    as well as the set specified by `-spec`.
-    Can be given multiple times.
-  * All remaining targets are arbitrary `make` options or
-    targets in the Makefile.
-
-The `target(s)` passed to these scripts are arbitrary `make` options, and
-can be used to set Makefile variables and options discussed above, as well
-as specify actual build targets.
-For example, to build the HTML specification with all KHR extensions
-included as well as a single vendor extension:
-
-----
-$ ./makeSpec -clean -spec khr -extension VK_EXT_debug_report html
-----
-
-The scripts `makeAllExts`, `makeKHR`, and `makeExt` set appropriate options
-and invoke `makeSpec`, for backwards compatibility, but are no longer used
-by Khronos.
-
-The Makefile variable `$(APITITLE)` defines an additional string which is
-appended to the specification title.
-When building with extensions enabled, this should be set to something like
-`(with extension VK_extension_name)`.
-The `makeSpec` script already does this.
-
-The reference pages (the `manhtmlpages` target) must be built using the
-`-spec all` option; there are markup and scripting issues which will
-probably cause any more restricted set of refpages to fail to build.
-
-
-[[building-diff]]
-==== Building A Highlighted Extension Diff
-
-The `diff_html` target in the Makefile can be used to generate a version of
-the specification which highlights changes made to the specification by the
-inclusion of a particular set of extensions.
-
-Extensions in the Makefile variable `$(EXTENSIONS)` define the base
-extensions to be enabled by the specification, and these will not be
-highlighted in the output.
-Extensions in the Makefile variable `$(DIFFEXTENSIONS)` define the set of
-extensions whose changes to the text will be highlighted when they are
-enabled.
-Any extensions in both variables will be treated as if they were only
-included in `$(DIFFEXTENSIONS)`.
-`$(DIFFEXTENSIONS)` can be set when using the `makeSpec` script described
-above.
-
-In the resulting HTML document, content that has been added by one of the
-extensions will be highlighted with a lime background, and content that was
-removed will be highlighted with a pink background.
-Each section has an anchor of `#differenceN`, with an arrow (=>) at the end
-of each section which links to the next difference section.
-The first diff section is `#difference1`.
-
-[NOTE]
-.Note
-====
-This output is not without errors.
-It may instead result in visible `+++[.added]##content##+++` and
-`+++[.removed]##content##+++`, and so also highlights not being rendered.
-But such visible markup still correctly encapsulates the modified content.
-====
-
-[[building-test]]
-=== Alternate and Test Builds
-
-If you are just testing Asciidoctor formatting, macros, stylesheets, etc.,
-you may want to edit `vkspec.txt` to just include your test code.
-The asciidoctor HTML build is very fast, even for the whole Specification,
-but PDF builds take several minutes.
-
-
-=== Images Used In The Specification
-
-All images used in the specification are in the `images/` directory in the
-SVG format, and were created with Inkscape.
-We recommend using Inkscape to modify or create new images, as we've had
-problems using SVG files created by some other tools; especially in the PDF
-builds.
-
-
-[[validation-scripts]]
-=== Validation Scripts
-
-The `allchecks` Makefile target runs a Python script that looks for markup
-errors, missing interfaces, macro misuse, and inconsistencies in the
-specification text.
-This script is necessarily heuristic, since it's dealing with lots of
-hand-written material, but it identifies many problems and can suggest
-solutions.
-This script is also run as part of the CI tests in the internal Khronos
-gitlab repository.
-
-
-[[macros]]
-== Our Asciidoctor Macros
-
-We use many custom Ruby macros in the reference pages and API spec
-Asciidoctor sources.
-The validator scripts rely on these macros as part of their sanity checks,
-and you should use the macros whenever referring to an API command, struct,
-token, or enum name, so the documents are semantically tagged and more
-easily verifiable.
-
-The supported macros are defined in the `config/spec-macros/extension.rb`
-asciidoctor extension script.
-
-The tags used are described in the
-link:https://www.khronos.org/registry/vulkan/specs/1.1/styleguide.html[style
-guide] (generated from `styleguide.txt`).
-
-We (may) eventually tool up the spec and reference pages to the point that
-anywhere there's a type or token referred to, clicking on (or perhaps
-hovering over) it in the HTML view will take reader to the definition of
-that type/token.
-That will take some more plumbing work to tag the stuff in the autogenerated
-include files, and do something sensible in the spec (e.g. resolve links to
-internal references).
-
-Most of these macros deeply need more intuitive names.
-
-
-[[refpages]]
-== Reference Pages
-
-The reference pages are extracted from the API Specification source, which
-has been tagged to help identify boundaries of language talking about
-different commands, structures, enumerants, and other types.
-A set of Python scripts extract and lightly massage the relevant tagged
-language into corresponding reference page sources.
-
-To regenerate the reference page sources from scratch yourself, execute:
-
-----
-./makeSpec -spec all refpages
-----
-
-The `genRef.py` script will generate many warnings, but most are just
-reminders that some pages are automatically generated.
-If everything is working correctly, all the `$(GENERATED)/refpage/*.txt`
-files will be regenerated, but their contents will not change.
-
-If you add new API features to the Specification in a branch, make sure that
-the commands have the required tagging and that reference pages are
-generated for them, and build properly.
-
-When executing the `manhtmlpages` target in the Makefile, after building
-HTML versions of all reference pages extracted from the spec, symbolic links
-from aliases to the reference page for the API they alias will also be
-created.
-
-
-[[styles]]
-== Our stylesheets
-
-We use an HTML stylesheet `config/khronos.css` derived from the
-http://asciidoctor.org/docs/produce-custom-themes-using-asciidoctor-stylesheet-factory/[Asciidoctor
-stylesheet factory] "`colony`" theme, with the default Arial font family
-replaced by the sans-serif https://en.wikipedia.org/wiki/Noto_fonts[Noto
-font family].
-
-
-[[styleguide]]
-== Vulkan Style Guide
-
-
-If you're writing new spec language or modifying existing language, see the
-link:https://www.khronos.org/registry/vulkan/specs/1.2/styleguide.html["`style
-guide`"] (formally titled "`Vulkan Documentation and Extensions: Procedures
-and Conventions`") document for details of our asciidoctor macros,
-extensions, mathematical equation markup, writing style, etc.
-
-
-[[depends]]
-== Software Dependencies
-
-This section describes the software components used by the Vulkan spec
-toolchain.
-
-In the past, we previously specified package versions and instructions for
-installing the toolchain in multiple desktop environments including Linux,
-MacOS X, and Microsoft Windows.
-The underlying components evolve rapidly, and we have not kept those
-instructions up to date.
-
-
-[[depends-docker]]
-=== Khronos-Provided Docker Image
-
-Khronos has published a Docker image containing a Debian Linux distribution
-with the entire toolchain preinstalled.
-
-We will occasionally update this image if needed, and we recommend people
-needing to build from this repository use the Docker image.
-
-Docker installation is beyond the scope of this document.
-Refer to link:https://docs.docker.com/get-docker/[the Docker website] for
-information about installing Docker on Linux, Windows, and MacOS X.
-
-The name of the build image is
-
-    khronosgroup/docker-images:asciidoctor-spec
-
-It can be pulled from the
-link:https://hub.docker.com/repository/docker/khronosgroup/docker-images[Dockerhub
-repository] with the command
-
-    docker pull khronosgroup/docker-images:asciidoctor-spec
-
-Once docker is installed and the image is available, it can be executed as
-described above under <<building, Building the Spec>> to generate
-Specification output documents or other Makefile targets.
-
-[NOTE]
-.Note
-====
-The old `vulkan-docs-base` and `vulkan-docs` images continue to be hosted,
-but the new `asciidoctor-spec` image is preferred - the added functionality
-of `vulkan-docs`, to set the user/group inside Docker based on environment
-variables passed into Docker, is no longer needed with the Docker `--user`
-option.
-====
-
-
-[[depends-nondocker]]
-=== Non-Docker Build Environments
-
-We do not actively support building outside of our Docker image, but it is
-straightforward to reproduce our toolchain in a Debian (or similar APT-based
-Linux) distribution by executing the same steps as the
-link:https://github.com/KhronosGroup/DockerContainers/blob/master/asciidoctor-spec.dockerfile[Dockerfile]
-used to build our Docker image.
-
-It should be possible to apply the same steps in a Windows Subsystem for
-Linux (WSL2) environment on Windows 10, as well.
-
-For other native environments, such as MacOS X and older Unix-like
-environments for Windows such as MinGW and Cygwin, we provided instructions
-in older versions of this document.
-While those instructions are out of date and have been removed from current
-versions of this document, you may be able to make use of
-link:https://github.com/KhronosGroup/Vulkan-Docs/blob/v1.2.135/BUILD.adoc#depends[the
-version of BUILD.adoc in the v1.2.135 repository tag]
-
-[NOTE]
-.Note
-====
-While we have no intention of forcing people to use our Docker image, we
-cannot support every possible environment.
-The Docker image is a straightforward way to use the Vulkan-Docs repository
-with almost all modern desktop environments.

-  license identifier "`CC-BY-4.0`").
-* Header files, scripts, programs, XML files, and other tooling used or
-  generated as part of the build process are typically licensed under the
-  Apache License, Version 2.0 (SPDX license identifier "`Apache-2.0`").
-* For compatibility with external developers working in GPLed projects who
-  have requested it, link:xml/vk.xml[`vk.xml`] is licensed under a dual
-  (SPDX license identifier "`Apache-2.0 OR MIT`" License).
-* Fonts derived from the M+ Font Project, found in
-  link:config/fonts/[`config/fonts/`] are licensed under the M+ Font License
-  (SPDX license identifier "`LicenseRef-MPLUS`"). This is an open source
-  license but is not OSI-approved, and is found at
-  https://osdn.net/softwaremap/trove_list.php?form_cat=370
-* Code which converts the single-file HTML specification to a chunked
-  HTML document, kept in
-  link:scripts/asciidoctor-chunker[`scripts/asciidoctor-chunker`], is
-  licensed under the MIT license. The home of the
-  link:https://github.com/wshito/asciidoctor-chunker[chunker project] is
-  found on github.
-* There are a few remaining files adopted from other open source projects,
-  such as a copy of the KaTeX distribution. Such files continue under their
-  original MIT licenses, or in a few cases, like
-  link:scripts/htmldiff/htmldiff[`scripts/htmldiff/htmldiff`], had no
-  license statement. We have not added SPDX license identifiers to such
-  externally originated files.
-* Some generated, transient files produced during the course of building the
-  specification, headers, or other targets may not have copyrights. These
-  are typically very short asciidoc fragments describing parts of the Vulkan
-  API, and are incorporated by reference into specification or reference
-  page builds.
-
-Users outside Khronos who create and post Vulkan Specifications, whether
-modified or not, should use the CC-BY-4.0 license on the *output* documents
-(HTML, PDF, etc.) they generate. This is the default when building the
-Specification.
-
-
-== Frequently Asked Questions
-
-Q: Why are the HTML and PDF Specifications posted on Khronos' website under
-a license which is neither CC-BY nor Apache-2.0?
-
-A: The Specifications posted by Khronos in the Vulkan Registry are licensed
-under the proprietary Khronos Specification License. Only these
-Specifications are Ratified by the Khronos Board of Promoters, and therefore
-they are the only Specifications covered by the Khronos Intellectual
-Property Rights Policy.
-
-
-Q: Does Khronos allow the creation and distribution of modified versions of
-the Vulkan Specification, such as translations to other languages?
-
-A: Yes. Such modified Specifications, since they are not created by Khronos,
-should be placed under the CC-BY license. If you believe your modifications
-are of general interest, consider contributing them back by making a pull
-request (PR) on the Vulkan-Docs project.
-
-
-Q: Can I contribute changes to the Vulkan Specification?
-
-A: Yes, by opening an Issue or Pull Request (PR) on the
-link:https://github.com/KhronosGroup/Vulkan-Docs/[Vulkan-Docs] Github
-project.
-You must execute a click-through Contributor License Agreement, which brings
-your changes under the umbrella of the Khronos IP policy.
-
-
-Q: Can you change the license on your files so they're compatible with my
-license?
-
-A: We are using a dual license license on `vk.xml`, to make it compatible
-with GPL-licensed projects such as externally-generated language bindings.
-This replaces an earlier Apache 2.0 + "Exception Clause" license on the file
-with a more standard methodology, and allows use of the SPDX license
-identifier "`Apache-2.0 OR MIT`" to denote the license.
-
-If you *require* GPL compatibility for use of other Apache-2.0 licensed
-files in our repository, please raise an issue identifying the files and we
-will consider changing those specific files to the dual license as well.

-Update Log for the Vulkan-Docs repository on Github. Updates are in reverse
-chronological order starting with the latest public release.
-
-This summarizes the periodic public updates, not individual commits. Updates

-    `scripts/xml_consistency.py` to try and detect future occurrences
-    (internal issue 2810).
-  * Add missing pname:sType and pname:pNext boilerplate descriptions to spec
-    language for several elink:*Features structures that were missing it

-    holiday meeting schedule.
-
-Github Issues:
-
-  * Make treatment of empty etext:Vk*FlagBits types consistent in `vk.xml`
-    (public issue 1601 and merge request 1609)
-
-Internal Issues:

-     (internal issue 1598).
-  ** Remove asciidoctor conditional check for
-     `VK_KHR_storage_buffer_storage_class`, not needed because the SPIR-V
-     specification is unified and `spirv-val` will throw an error if trying
-     to use code:StorageBuffer without the proper extension / version being
-     set (internal merge request 4779).

-    next SDK update (public pull request 1610).
-
-Internal Issues:
-
-  * Use `hexapdf` for PDF optimization, rather than Ghostscript. This
-    improves overall PDF generation time about 15-20%, and final PDF size by
-    about 1/3 (internal issue 2422).
-  * Improve contrast for better accessibility of HTML outputs, based on
-    feedback from the ANDI tool. This includes updating the specification

-    `scripts/xml_consistency.py` in CI, and add check for this case (public
-    pull request 1597).
-  * Add missing markup (setting `refpage` attributes where they were needed
-    for commonvalidity statements) to fix some broken valid usage ID link
-    names (public issue 1598).
-  * Update valid usage statement 02650 to use "`potential format features`"
-    consistently with other recent changes (discussion on public
-    Vulkan-ValidationLayers pull request 3139).
-
-Internal Issues:
-
-  * Clarify the role of <<ray-traversal-culling-face, face winding>> in the

-    ename:VK_GEOMETRY_INSTANCE_TRIANGLE_FRONT_COUNTERCLOCKWISE_BIT_KHR to
-    ename:VK_GEOMETRY_INSTANCE_TRIANGLE_FLIP_FACING_BIT_KHR, corresponding
-    to the clarifications (internal issue 2780).
-  * Add valid usage statement for flink:vkCmdBeginTransformFeedbackEXT
-    requiring a valid graphics pipeline be bound (internal issue 2785).
-  * Use the term <<acceleration-structure-def, "`constructed`">> to refer to
-    an acceleration structure that was previously built or created by
-    copying or deserialization of a built acceleration structure (internal
-    merge request 4727).
-  * Add explicit valid usage statements to flink:vkWaitForPresentKHR and
-    slink:VkPresentInfoKHR requiring the corresponding features be enabled
-    (internal merge request 4754).
-  * Remove extraneous trailing periods from some valid usage statements
-    (internal merge request 4759).

-
-Internal Issues:
-
-  * Clarify that depth values outside the range [0,1] become undefined
-    following the depthClamp stage of the pipeline, by rearranging the
-    <<fragops-depth, Depth Test>> section and adding a new "`Depth Clamping
-    and Range Adjustment`" subsection (internal issues 2445, 2753).
-  * Clarify valid usage statement 01843 for slink:VkDeviceQueueInfo2 to
-    match similar statement for flink:vkGetDeviceQueue, and split off part

-  * Fix a few enumerant and member names in the provisional video extensions
-    to comply with the spec style guidelinse (internal issue 2710).
-  * Update the descriptions of flink:vkCmdDrawMultiEXT and

-    calling underlying drawing commands multiple times with different
-    parameters (internal issue 2757).
-  * Renumber VUIDs which duplicated the numeric portion of another
-    non-common VUID, and add a duplicate number detection test to CI to
-    prevent recurrences (internal issue 2764).
-  * Make code:SubgroupSize command scope uniform in compute dispatches
-    (internal issue 2773).
-  * Expand the list of valid image layouts for
-    <<attachment-type-imagelayout, input attachments>>,
-    <<descriptorsets-sampleimage, sampled images>>, and
-    <<descriptorsets-combinedimagesampler, combined image samplers>> to
-    include DEPTH_READ_ONLY_OPTIMAL and STENCIL_READ_ONLY_OPTIMAL (internal

-    than "`distance in bytes`" in a few places (public issue 1575)
-  * Clarify the equivalence of flink:vkQueueWaitIdle to
-    fence submission (public issue 1579).
-  * Fix XML capabilities for new code:*Float*Atomic* SPIR-V capabilities to
-    require slink:VkPhysicalDeviceShaderAtomicFloat2FeaturesEXT rather than
-    slink:VkPhysicalDeviceShaderAtomicFloatFeaturesEXT (public pull request
-    1587, although fixed internally first).
-
-Internal Issues:
-
-  * Refactor asciidoctor conditionals imbedded within valid usage statements

-
-Internal Issues:
-
-  * Document in the <<extendingvulkan-extensions-extensiondependencies,
-    Extension Dependencies>> section that instance extensions do not have

-    instead of the previous "`Layout for pipeline cache header version one`"
-    table (internal merge request 4011).
-  * Make the `requires` attribute of the `spirvcapability` XML tag required
-    when specifying a structure, even if what's required is

-  * Add a NOTE to the <<interfaces, Shader Interfaces>> chapter that SPIR-V
-    execution model keywords with extension suffixes will always be present
-    in spec builds, even in a build not supporting any extensions, since
-    these keywords appear in the unified SPIR-V specification without such
-    qualifiers (public issue 1483, internal issue 2621).
-  * Modify `vk.xml` to include the Vulkan platform header via the path
-    `vulkan/vk_platform.h` rather than just `vk_platform.h`

-
-  * Update release number to 181 for this update.
-
-Github Issues:
-
-  * Add stub slink:VkPipelineLayoutCreateFlagBits <enum> type in `vk.xml` to
-    reduce spurious warnings from XML processing scripts that don't respect

-    documentation to make more clear that `extension` tags with this
-    attribute should not be processed (public issue 1549).
-
-Internal Issues:
-
-  * Clarify implicit conversions between the vertex input attribute
-    description format and the shader vertex attribute input type in the
-    <<fxvertex-attrib-location, Attribute Location and Component
-    Assignment>> and <<fxvertex-input-extraction>> sections (internal issue
-    902).

-    of empty structures>> (internal issue 2174).
-  * Clarify the use of rasterization order <<primsrast-order,
-    "`operations`">> (internal merge request 4582).
-  * Allow any pipeline barrier command for queue transfers in the
-    <<synchronization-queue-transfers, Queue Family Ownership Transfer>>
-    section (internal merge request 4596).
-  * Remove potentially confusing reference to
-    ename:VK_ERROR_INVALID_SHADER_NV in the description of
-    flink:vkCreateShaderModule (internal merge request 4602).
-  * Improve visibility of instance creation callbacks by migrating some
-    language from the `<<VK_EXT_debug_report>>` and `<<VK_EXT_debug_utils>>`

-    intended purpose, although it also make these images in the HTML output
-    show the same artifacts as the PDF output.

-    `<<VK_KHR_deferred_host_operations>>` appendix (internal issue 2677).
-  * Add a NOTE to slink:VkAccelerationStructureCompatibilityKHR encouraging
-    host-cachable memory for host acceleration structure builds (internal
-    issue 2682).
-  * Remove redundant language in basetype:VkSampleMask duplicating valid

-  * Update release number to 178 for this update.
-
-Github Issues:
-
-  * Add `optional` attribute to pname:pFragmentShadingRateAttachment member
-    of slink:VkFragmentShadingRateAttachmentInfoKHR, to match specification
-    text (public issue 1482).
-  * Lots of minor markup and phrasing fixes (public issue 1482).

-  * Fix formatting around "`Special Use`" sections in generated refpages
-    (public issue 1518).
-
-Internal Issues:
-
-  * Language cleanup including removing contractions, and some wording in

-  * Make parameter handling text in the
-    <<deferred-host-operations-requesting, Requesting Deferral>> section
-    consistent with the <<fundamentals>> chapter (internal issue 2018).
-  * Relax slink:VkCopyDescriptorSet valid usage statements to remove some

-    other kinds of sets (internal issue 2610).
-  * Clarify the definition of "`intersection`" in the

-    Determination>> section (internal issue 2623).
-  * Allow pname:stride to equal buffer size in
-    slink:VkStridedDeviceAddressRegionKHR (internal issue 2631).
-  * Fix the ray tracing shader interface table in the
-    <<interfaces-raypipeline, Ray Tracing Pipeline Interface>> section
-    (internal issue 2640).
-  * Try to use consistently-phrased descriptions of etext:*FlagBits* members
-    and parameters everywhere (internal issue 2656).
-  * Replace "`optional pointer`" terminology with "`NULL or a pointer`" (and
-    similar uses), and update the style guide accordingly (internal issue

-  * Update release number to 177 for this update.
-
-Github Issues:
-
-  * Add valid usage statement to flink:vkDestroyImage to prevent destruction
-    of presentable images acquired from flink:vkGetSwapchainImagesKHR
-    (public Vulkan-ValidationLayers issue 2718).
-
-Internal Issues:
-
-  * Add proposal template for new feature development (internal issue 2529).
-  * Remove valid usage statement 03361 from flink:vkCmdBindVertexBuffers2EXT
-    (internal issue 2600).
-  * Finish fixing refpage formatting issues for the new video extensions

-    test>> (internal merge request 4480).
-  * Fix capitalization of etext:*_EXTENSION_NAME and etext:*_SPEC_VERSION
-    tokens for `<<VK_QCOM_render_pass_store_ops>>` (internal merge request
-    4490).
-  * Don't generate etext:*_MAX_ENUM tokens for 64-bit flag types. Note that
-    these tokens are *explicitly* not part of the Vulkan API and are not
-    included in the Specification, only in generated headers. They are added
-    to enumerated types to ensure padding to 32 bits, but are completely
-    pointless for the 64-bit flag types, which are defined as integer
-    constants rather than enumerants (internal merge request 4493).
-  * Remove empty VK_ENABLE_BETA_EXTENSION guards from headers when disabling
-    extensions (internal merge request 4498).
-  * Reproduce valid usage statement constraining pname:query from
-    flink:vkCmdBeginQuery to
-    flink:vkCmdWriteAccelerationStructuresPropertiesKHR (internal merge

-
-Github Issues:

-  * Fix many typos (based on public issues 1483 & 1484).
-  * Fix an error in the definition of dname:VK_NULL_HANDLE which caused a

-  * Remove duplicate requirement for elink:VkStructureType from
-    dname:VK_VERSION_1_0 block of `vk.xml` (public merge request 1504).
-

-    for new extensions (internal merge request 4491).
-  * Clean up latest revision numbers in some video extension appendices to
-    be integers, for compatibility with the consistency checker script
-    (internal merge request 4492).

-Change log for April 13, 2021 Vulkan 1.2.175 spec update:
-
-  * Update release number to 175 for this update.
-
-Github Issues:
-
-  * Specify that fragment shader invocations in the same quad scope are also
-    in the same primitive scope (public issue 1465).
-  * Fix an incorrect reference to ename:VK_SHARING_MODE_CONCURRENT to the
-    correct ename:VK_SHARING_MODE_EXCLUSIVE in the queue transfer wording
-    for slink:VkBufferMemoryBarrier2KHR (public issue 1479).
-  * Fix description of <<vertexpostproc-clipping, Primitive Clipping>>
-    (public issues 1480 and 1481).
-
-Internal Issues:
-
-  * Use consistent language in describing <<features, feature>> and
-    <<limits, property (limit)>> queries. In particular, a few structures
-    were described as being usable to query feature support, but not to set
-    it. This was incorrect. All feature structures which can appear in the
-    pname:pNext chain of slink:VkPhysicalDeviceFeatures2 can be used to both
-    query and set (internal issue 2310).
-  * Add `limittype` attributes to the XML schema and to `vk.xml` for
-    structure members which are part of physical device property queries, to
-    annotate how the resulting properties are interpreted and replace some
-    manual interpretation of these properties (internal issue 2427).
-  * Improve slink:VkAttachmentDescription2 wording around the use of
-    slink:VkAttachmentDescriptionStencilLayout for specifying the stencil
-    aspect layout (internal issue 2496).
-  * Split the <<extendingvulkan-coreversions-versionnumbers, major version
-    field>> of a packed pname:apiVersion value, introducing a new `variant`
-    field. This field allows identification of APIs based on Vulkan, but not
-    fully compatible with Vulkan applications. Vulkan is variant 0, making
-    the change backwards compatible with the previous definition of
-    pname:apiVersion. This change was introduced to enable variants of the
-    Vulkan API that Khronos may release in the future, in particular the
-    in-development Vulkan SC API. It is purely a future-proofing measure and
-    no near-term further use is planned. To support this split, a set of new
-    macros is introduced: dname:VK_API_VERSION_VARIANT,
-    dname:VK_API_VERSION_MAJOR, dname:VK_API_VERSION_MINOR, and
-    dname:VK_API_VERSION_PATCH (internal issue 2531).
-  * Clarify that the slink:VkRectLayerKHR members of a
-    slink:VkPresentRegionKHR structure must not be transformed to align with
-    the swapchain's pname:pTransform. The presentation engine must do this
-    transform (internal issue 2571).
-  * Fix minor issues with exposed asciidoctor markup in spec outputs
-    (internal issue 2576).
-  * Tighten up wording around pool entries of mutable descriptor types. for
-    slink:VkDescriptorPoolCreateInfo (internal issue 2578).
-  * Expand on wording of code:FPRoundingMode valid usage statement in the
-    <<spirvenv-module-validation-standalone, Standalone SPIR-V Validation>>
-    section (internal merge request 4298).
-  * Document interaction with `<<VK_KHR_fragment_shading_rate>>` for
-    `<<VK_QCOM_render_pass_transform>>` (internal merge request 4221).
-  * Require compile-time constants be explicitly tagged as unsigned or float
-    in `vk.xml`. Modify the generator scripts and schema documentation to
-    require `type` attributes for such constants. This allows generating
-    headers compliant with MISRA section 10.4 requirements, where needed
-    (internal merge request 4451).
-  * Minor editorial fixes (internal merge request 4454).
-  * Disallow code:*Offset* decorations on storage images
-    in the <<spirvenv-module-validation-standalone, Standalone SPIR-V
-    Validation>> section (internal merge request 4465).
-  * Improve the code: macro used in spec markup to allow imbedded wildcards
-    separating words and a trailing wildcard (internal merge request 4466).
-  * Modify `vk.xml` `requires` attributes to reorder definitions of
-    dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE and dname:VK_NULL_HANDLE. This
-    prevents a corner case where the app overriding the first macro
-    explicitly would prevent definition of dname:VK_NULL_HANDLE (internal
-    merge request 4476).

-Change log for March 29, 2021 Vulkan 1.2.174 spec update:
-
-  * Update release number to 174 for this update.
-
-Github Issues:
-
-  * Add a common header macro dname:VK_USE_64_BIT_PTR_DEFINES to specify at
-    compile time whether non-dispatchable handles are declared using a
-    64-bit pointer type, or a 64-bit unsigned interger type. NOTE: it is
-    possible that the complex platform-dependent C preprocessor block will
-    move from vk.xml into the static (non-generated) vk_platform.h header in
-    the near future (partially addresses public issue 1431, in addition to
-    internal needs).
-  * Clarify code:PatchVertices documentation for tessellation shaders
-    (public pull request 1475).
-
-Internal Issues:
-
-  * Add valid usage statements restricting bitfield operations to 32-bit
-    types in the <<spirvenv-module-validation-standalone, Standalone SPIR-V
-    Validation>> section (internal issue 2561).
-  * Update registry documentation to require providing the `type` attribute
-    of `enum` tags when they are specifying compile-time constants, and
-    change the accepted values of the attribute to a small set of C scalar
-    type names, instead of schema-specific names. The XML schema itself
-    would ideally be updated to match, but we don't know how to do that yet
-    (internal issue 2564). NOTE: it is possible this will affect downstream
-    consumers of `vk.xml`, although we consider this unlikely.
-  * Document in the style guide that bits reserved in corresponding 32- and
-    64-bit bitmasks should be reserved in both types (internal merge issue
-    2565).
-  * Add output generator options to generate MISRA-friendly headers, and
-    check generator scripts to avoid generating etext:RESERVED 64-bit
-    bitflag names specified by `disabled` extensions in `vk.xml` (internal
-    merge request 4239, internal issue 2572).
-  * Clarify that compressed copies need to round up division in the
-    computation `rowLength` and `imageHeight` in the sample code for the
-    <<copies-buffers-images-addressing, Buffer and Image Addressing>>
-    section (internal merge request 4439).

-
-Github Issues:
-
-  * Fix valid usage statement for flink:vkCmdBeginQueryIndexedEXT to allow
-    multiple active queries of the same type, as long as their index values
-    are different (public issue 1357).
-  * Fix tagging for slink:VkPhysicalDeviceVulkan11Features in `vk.xml`
-    (public issue 1437).
-  * Update the <<WSI Swapchain>> chapter's use of "`release`" and
-    "`present`" terminology (public pull request 1470).
-  * Migrate from Azure Pipelines to Github Actions for CI, and use updated
-    Khronos Docker image to build (public pull request 1473).
-
-Internal Issues:
-
-  * Document requirements for extension <<extensions-feature-structures,
-    Feature Structures>> (internal issue 2503).
-  * Add missing valid usage statements for slink:VkAttachmentReference2 and

-  * Clarify interactions between `<<VK_EXT_buffer_device_address>>` and
-    Vulkan 1.2 in slink:VkDeviceCreateInfo valid usage (internal issue
-    2530).
-  * Allow variation in number of acceleration structure handles following a
-    top-level acceleration structures for
-    flink:vkCmdCopyAccelerationStructureToMemoryKHR (internal issue 2538).
-  * Specify implementation requirement for device timestamps in the
-    description of elink:VkTimeDomainEXT (internal issue 2551).
-  * Update valid usage ID assignment and extraction scripts to handle IDs
-    containing function pointer names (internal issue 2557).
-  * Move some runtime restrictions to
-    <<spirvenv-module-validation-standalone Standalone SPIR-V>> valid usage
-    statements (internal merge request 4286).
-  * Use new version of the HTML asciidoctor-chunker, which runs much faster,
-    and a new Docker image which omits the old implementation of the chunker
-    (internal merge request 4391).
-  * Fix <<devsandqueues-devices, logical device creation language>> for
-    Vulkan 1.1 (internal merge request 4405).
-  * Modify scripts to enable platform extensions to be filtered by the
-    `"supported"` attribute in `vk.xml` (internal merge request 4411).
-  * Add common valid usage statement for draw/dispatch commands on format
-    support for mip filters (internal merge request 4413).
-  * Fix valid usage statement extractor (vu-to-json) to add padding after
-    inserted list items, so they don't absorb other markup that might come
-    after in the document (internal merge request 4423).
-  * Disallow shadow lookups on 3D images in the
-    <<spirvenv-module-validation-standalone, Standalone SPIR-V Validation>>
-    section. This is not supported on all hardware, and should not have been
-    allowed (internal merge request 4424).

-    <<spirvenv-module-validation-standalone, Standalone SPIR-V valid usage
-    statements>>, and add a note to this effect for future additions
-    (internal issue 2512).
-  * Update the descriptions (and related validation rules) of
-    code:uniformAndStorageBuffer8BitAccess and
-    code:uniformAndStorageBuffer16BitAccess to only refer to the
-    code:Uniform storage class; and update the 16-bit storage feature
-    validation rules to refer to 16-bit floating-point, similarly to the
-    feature descriptions. These changes are in the
-    <<spirvenv-module-validation-runtime, Runtime SPIR-V Validation>>
-    <<features-requirements, Feature Requirements>> sections (internal issue
-    2535).
-  * Ban recursion in tlink:PFN_vkDebugUtilsMessengerCallbackEXT callbacks,
-    for consistency of `<<VK_EXT_debug_utils_callbacks>>` with
-    `<<VK_EXT_device_memory_report>>` and the rules for
-    slink:VkAllocationCallbacks (internal issue 2537).
-  * Remove dependency on `<<VK_KHR_create_renderpass2>>` from `vk.xml` for
-    `<<VK_KHR_synchronization2>>` (internal issue 2539).
-  * Add the transform feedback pipeline stage as valid for
-    ename:VK_ACCESS_TRANSFORM_FEEDBACK_COUNTER_READ_BIT_EXT access (internal
-    merge request 4355).
-  * Fix typo in `<<VK_EXT_debug_utils>>` examples (internal merge request
-    4395).
-  * Fix typo to refer to "`buffer view`" rather than "`image view`" in the

-  * Correct the <<interfaces-resources-setandbinding, DescriptorSet and
-    Binding Assignment>> "`noteworthy example`" to refer to code:OpTypeImage
-    code:Samplerd=1, not code:OpTypeSampler code:Sampled=1 (public pull
-    request 1459).
-  * Clarify that the value of slink:VkViewport::pname:minDepth is not
-    restricted relative to pname:maxDepth (Vulkan-Headers public issue 180).
-  * Add valid usage statement to <<spirvenv-module-validation-standalone,

-Internal Issues:
-
-  * Add missing query types to the the introduction of the <<queries>>
-    chapter (internal issue 2488).
-  * Tag use of union types in `vk.xml` as `noautovalidity`, since we don't
-    generate meaningful valid usage statements or validation layer code at
-    present. This removes a few nonsensical, and unimplemented valid usage
-    statements of form 'ptext:param must: be a valid stext:VkUnionType union
-    (internal issue 2490).
-  * Flatten inline lists in valid usage statements in the

-  * Clarify the definition of the `optional='true'` XML attribute to allow
-    its use with scalar types, and use it consistently in the specification
-    and XML; this removes a few uses of the attribute and simplifies some
-    valid usage statements (internal issue 2435).
-  * Clarify that it is not valid to create an image view using a format that
-    requires YCbCr conversion without passing a
-    slink:VkSamplerYcbcrConversion in valid usage for

-    `<<VK_EXT_transform_feedback>>` extension appendix (internal issue
-    2477).
-  * Restrict code:OpImageQueryLod, code:OpImageQuerySizeLod, and
-    code:OpImageQueryLevels to require a sampler (not storage image) in the
-    <<spirvenv-module-validation-standalone, Standalone SPIR-V Validation>>
-    section (internal issue 2478).
-  * Allow
-    flink:vkGetAccelerationStructureBuildSizesKHR::pname:pMaxPrimitiveCounts
-    to be zero by setting the `optional` attribute in the XML (internal
-    issue 2480).
-  * Update description of

-    requiring that all linked pipelines have the same set of flags specified
-    from the etext:VK_PIPELINE_CREATE_RAY_TRACING_* bits (internal issue
-    2489).
-  * Add valid usage statements to flink:vkCmdBeginQuery /
-    flink:vkCmdBeginQueryIndexedEXT to disallow use with pools created with
-    ename:VK_QUERY_TYPE_ACCELERATION_STRUCTURE_COMPACTED_SIZE_KHR /
-    ename:VK_QUERY_TYPE_ACCELERATION_STRUCTURE_SERIALIZATION_SIZE_KHR types
-    (internal issue 2493).

-    extensions in valid usage statements (internal merge request 4293)
-  * Update and futureproof a previously hardwired reference to Vulkan 1.1 in
-    the <<introduction-conventions, Document Conventions>> section (internal
-    merge request 4295).
-  * Add code:PhysicalStorageBuffer as a valid atomic storage class in the
-    <<spirvenv-module-validation-standalone, Standalone SPIR-V Validation>>
-    section (internal merge request 4296).
-  * Clean up phrasing of valid usage statements in the
-    <<spirvenv-module-validation-standalone, Standalone SPIR-V Validation>>
-    section (internal merge request 4297).
-  * Add shared valid usage statement for buffer copy commands requiring
-    pname:bufferRowLength to fit in a signed 32-bit integer (internal merge
-    request 4302).
-  * Add dname:VK_NO_STDDEF_H to allow apps to prevent including
-    `<stddef.h>`, and document it in the <<boilerplate, API Boilerplate>>
-    appendix (internal merge request 4312).
-  * Fix typo `SkipTrianglesKHR` -> `SkipAABBsKHR` in the

-    clarifying the difference between undefined results and undefined
-    behavior (internal issue 543).
-  * Add valid usage statement to common indirect draw valid usage statements
-    requiring that the pname:countBufferOffset to the count being used lie
-    within the pname:countBuffer (internal issue 1309).

-    (internal issues 2094, 2237).
-  * Add valid usage statement to flink:vkCmdBeginTransformFeedbackEXT to
-    require that the last vertex processing stage of the bound graphics
-    pipeline be declared with the code:Xfb execution mode (internal issue
-    2124).
-  * Do not allow flink:vkWaitForFences or flink:kWaitSemaphores to return
-    timeouts before the period has expired, even though this is valid in
-    some other synchronisation APIs (internal issue 2146).
-  * Add elink:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_D3D11_FENCE_BIT as an alias
-    of elink:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_D3D12_FENCE_BIT for clarity
-    when interacting with D3D11 fences (internal issue 2175).
-  * Ignore slink:VkMemoryAllocateInfo::pname:allocationSize when importing

-  * Modify the validity generator so that, when generating valid usage for
-    array lengths with a chain of parameters (e.g. pname:pFoo->bar), don'
-    non-zero values are not required if any parameter in the chain is
-    optional, and consider the last parameter only when deciding the type of
-    the parameter (internal merge request 4021).
-  * Fix a typo in the `<<VK_EXT_fragment_density_map2>>` extension appendix
-    markup that caused refpage build warnings, and modify CI and
-    `BUILD.adoc` to use `makeSpec` instead of the old `makeAllExts` script
-    (internal merge request 4023).

-Change log for July 13, 2020 Vulkan 1.2.147 spec update:
-
-  * Update release number to 147 for this update.
-
-Github Issues:
-
-  * Allow physical-device-level structures in pname:pNext chains (public

-    <<spirvenv-module-validation-standalone, only be written in intersection
-    shaders>> (internal issue 2103).
-  * Specify that acceleration structure scratch buffer accesses from
-    acceleration structure build should be synchronized with the
-    ename:VK_PIPELINE_STAGE_ACCELERATION_STRUCTURE_BUILD_BIT_KHR pipeline
-    stage and an access mask of
-    ename:VK_ACCESS_ACCELERATION_STRUCTURE_READ_BIT_KHR or
-    ename:VK_ACCESS_ACCELERATION_STRUCTURE_WRITE_BIT_KHR (internal issue
-    2173).
-  * Improve description of 3D blitting in flink:vkCmdBlitImage (internal
-    issue 2212).
-  * Split <<fragops-coverage-reduction, Coverage Reduction>> section into
-    multiple steps when multi-pixel fragments are involved: first per-pixel
-    coverage is separated out, then per-sample coverage is generated for
-    each color sample from per-pixel coverage. dditionally, the definition
-    of "`color sample mask`" and discussions of it have been removed in
-    favour of the per-color-sample coverage. (internal merge request 3951).
-  * Modify slink:VkSamplerYcbcrConversionCreateInfo valid usage statements,
-    as well as the <<textures-chroma-reconstruction, Chroma Reconstruction>>
-    section, to make it clear the values of pname:xChromaOffset and
-    pname:yChromaOffset are only validated when chroma channels are
-    downsampled (internal merge request 3959).
-  * Allow flink:vkGetBufferMemoryRequrements and

-    (internal merge request 3988).
-  * Add valid usage statement to slink:VkImageCreateInfo requiring that
-    images with linear tiling cannot have sparse residency (internal merge
-    request 3988).
-  * Clarify that the ptext:maxPerStageDesciptorUpdateAfterBind*
-    <<limits-required, Required Limits>> must be at least the corresponding
-    non- ptext:UpdateAfterBind limits (internal merge request 3992).

-  * Fix valid usage generation script for optional bitmasks in a
-    non-optional array (public pull request 1228).
-  * Add lunr to `package.json` and update the locally cached copy (public
-    pull request 1238).
-  * Require that newly released extensions have etext:*_SPEC_VERSION `1`
-    (public issue 1263).
-  * Add to the NOTE in slink:VkPhysicalDeviceIDProperties, advising
-    implementations on returning unique pname:deviceUUID values and avoiding
-    hardwired values, especially 0 (public issue 1273).
-  * Add noscript fallback for HTML output (public pull request 1289).
-  * Fix duplicated VUIDs in flink:vkCmdExecuteGeneratedCommandsNV (public
-    pull request 1304).

-    markup, and linear equation markup in
-    <<textures-unnormalized-to-integer>> (public pull requests 1305, 1306,
-    1307).
-
-Internal Issues:
-
-  * Add comments to extending enums in the generated API interfaces showing
-    which core version and/or extensions provide the enum, matching recent
-    changes to show this information for commands and structures (internal
-    issue 1431).
-  * Only allow code:Invocation memory scope in the
-    <<spirvenv-module-validation-standalone, Standalone SPIR-V Validation>>
-    section when memory semantics is *None* (internal issue 1782).
-  * Make reflow script handle literal block delimiters and lines containing

-  * Clarify definition of <<limits-maxFragmentCombinedOutputResources,
-    pname:maxFragmentCombinedOutputResources>> (internal issue 2236).
-  * Add missing `errorcodes=` XML attributes for some
-    `<<VK_EXT_display_control>>` commands.

-Change log for June 20, 2020 Vulkan 1.2.145 spec update:
-
-  * Update release number to 145 for this update.
-
-Github Issues:
-
-  * Fix `<<VK_EXT_conservative_rasterization>>` interactions with external
-    SPIR-V and GLSL functionality in the extension appendix (public issue
-    1288).
-
-Internal Issues:
-
-  * Break SPIR-V validation into two sections,
-    <<spirvenv-module-validation-standalone, Standalone SPIR-V Validation>>
-    and <<spirvenv-module-validation-runtime, Runtime SPIR-V Validation>>
-    (internal issue 1598).
-  * Add VkFormat enums for ASTC 3D formats to `vk.xml`. These values are
-    slotted into the reserved, and still disabled extension 289. They will
-    not appear in the published `vulkan_core.h` header and there is no
-    published extension utilizing them, but this allows external projects
-    such as KTX2 to use these values as part of their internal cross-API
-    formats by generating a header including this disabled extension
-    (internal merge requests 1662, 2216).
-  * Synchronize that shader binding table accesses from ray tracing
-    pipelines should be synchronized with the
-    ename:VK_PIPELINE_STAGE_RAY_TRACING_SHADER_BIT_KHR pipeline stage and an
-    access mask of ename:VK_ACCESS_SHADER_READ_BIT (internal issue 1749).
-  * Validate that 3D image views are not used as attachments in
-    slink:VkFramebufferCreateInfo and slink:VkRenderPassAttachmentBeginInfo
-    (internal issue 2142).
-  * Increase the number of conditions recognized as build errors by the
-    valid usage extraction plugin (internal issue 2215).
-  * Relax slink:VkImportAndroidHardwareBufferInfoANDROID valid usage
-    statement 01881 to support external formats (internal issue 2220).
-  * Clearly define what "`optional capabilities`" means in the
-    <<spirvenv-capabilities, Capabilities>> section, and specify that if
-    *any* of the required core versions and/or extensions for a capability
-    is enabled, then it is valid to use that capability (internal merge
-    request 3827).
-  * Add ename:VK_FORMAT_B5G5R5_UNORM_PACK16 and
-    ename:VK_FORMAT_B5G5R5A1_UNORM_PACK16 to
-    `<<VK_EXT_custom_border_color>>` as exceptions when
-    <features-customBorderColorWithoutFormat>> is enabled (internal merge
-    request 3833).
-  * Add new <<spirvenv-format-type-matching, Image Format and Type
-    Matching>> section and refer to it from elsewhere in the spec,
-    clarifying rules regarding types for image operations (internal merge
-    request 3916).
-  * Fix typo sname:VkImageFormatProperties -> slink:VkFormatProperties
-    (internal merge request 3921).
-  * Move <<sparsememory-examples, sparse image examples>> to the Vulkan
-    Guide (internal merge request 3930).
-  * Fix typo in slink:VkAccelerationStructureBuildOffsetInfoKHR valid usage
-    statement 03553 (internal merge request 3938).
-  * Support <remove> tags for extending enumerants in XML (internal merge
-    request 3942).

-Change log for June 8, 2020 Vulkan 1.2.144 spec update:
-
-  * Update release number to 144 for this update.
-
-Internal Issues:
-
-  * Require `volatile` semantics for loading <<builtin-volatile-semantics,
-    certain variables used in ray pipeline stages>> in the
-    <<spirvenv-module-validation, Validation Rules within a Module>> and
-    also the <<ray-tracing-shader-call, Shader Call Instructions>> section
-    (internal issue 1924).
-  * Created new <<potential-format-features, Potential Format Features>>
-    section and corresponding glossary term, use the new term where
-    appropriate, and add some related valid usage statements to
-    flink:vkCmdBeginRenderPass, flink:vkCmdBeginRenderPass2,
-    slink:VkSubpassDescription, and slink:VkSubpassDescription2 (internal
-    issue 2031).
-  * Add interaction with `<<VK_KHR_ray_tracing>>` and corresponding `NV`
-    extension to flink:vkUpdateDescriptorSetWithTemplate (internal issue
-    2193).
-  * Resolve collisions in common VUID names using `{stageMaskName}`
-    qualifiers as part of the name and make fixes to
-    `config/vu-to-json/extension.rb` to match (internal issue 2215).
-  * Replace `shutil.move` operations with `copy` / `remove` in the base
-    `generator.py` code, working around a problem with bind mounts while
-    using the Khronos docker build image with `podman` instead of `docker`
-    (internal merge request 3872).
-  * Add a new <<spirvenv-extensions, SPIR-V Extensions>> subsection
-    containing a table showing the corresponding Vulkan extension or core
-    API required to support each of the SPIR-V extensions, replacing a
-    harder-to-read list of extensions (internal merge request 3876).
-  * Remove two redundant valid usage statements from flik:vkCmdResolveImage
-    (internal merge request 3878).
-  * Make repository REUSE-compliant, and run the `reuse` license checker as
-    part of internal CI. While most files now have SPDX license identifier
-    tags, some licenses are recorded in `.reuse/dep5` instead. Note that
-    this does not change licenses in the repository (aside from adding some
-    to files missing them), just insures that every file *has* an explicit
-    license (internal merge request 3904).
-  * Clarify that code:ImageMSArray is supported as part of the
-    <<features-shaderStorageImageMultisample>> feature (internal merge
-    request 3905).
-  * Reorganize some valid usage statements for flink:vkCmdBlitImage,
-    flink:vkCmdCopyBuffer, flink:vkCmdCopyBufferToImage,
-    flink:vkCmdCopyImage, flink:vkCmdCopyImageToBuffer, and
-    flink:vkCmdResolveImage as common valid usage statements, for
-    future-proofing (internal merge requests 3906, 3907, 3908, 3909, 3910).
-  * Add two valid usage statements to flink:vkAllocateMemory and
-    flink:vkCreateSampler for allocation limits of slink:VkDeviceMemory and
-    elink:VkSamplers, respectively (internal merge request 3923).
-
------------------------------------------------------
-
-Change log for June 8, 2020 Vulkan 1.2.143 spec update:
-
-  * Update release number to 143 for this update.
-  * Reorganize some valid usage statements for slink:VkBufferMemoryBarrier,
-    and for commands with elink:VkPipelineStageFlags parameters, as common
-    valid usage statements, for future-proofing (internal merge requests
-    3863, 3867).
-
-Github Issues:
-
-  * Move `translate_math.js` to the `scripts/` directory (public pull
-    request 1286).
-  * Minor cleanup of math markup (public pull request 1287).
-
-Internal Issues:
-
-  * Misc. licensing updates (internal issue 1017):
-  ** Replace the "`Exceptions`" clause on `vk.xml` with a dual Apache-2.0 OR
-     MIT license, with agreement of downstream developers known to be
-     affected by it. This enables use of `vk.xml` in GPLed projects under a
-     more widely used licensing scheme.
-  ** Use `SPDX-License-Identifier` tags in place of longer license text.
-     This does not change the license terms on files other than `vk.xml`,
-     but makes license statements in most files more compact.
-  ** Reorganize repository documentation (README.adoc, COPYING.adoc,
-     LICENSE.adoc, CONTRIBUTING.adoc, CODE_OF_CONDUCT.adoc, and BUILD.adoc)
-     with a more widely used split of information; make all of these files
-     Asciidoctor instead of Markdown format for consistency with the rest of
-     the repository; describe use of SPDX identifiers; and point to full
-     license text of the various OSS licenses used in the repository.
-  * Add new <<resources-image-views-identity-mappings, text describing the
-    identity swizzle>> incorporating the existing "`Component Mappings
-    Equivalent To ename:VK_COMPONENT_SWIZZLE_IDENTITY`" table, and refer to
-    this text in place of explicit references to
-    ename:VK_COMPONENT_SWIZZLE_IDENTITY in many places (internal merge
-    request 3399).
-  * Require code:storageBuffer16BitAccess capability if
-    `<<VK_KHR_16bit_storage>>` is enabled (internal merge request 3709).
-  * Added XML schema and generator script extensions to support 64-bit flags
-    and corresponding bitmasks (internal merge request 3718).
-  * Correct <<interfaces-resources-standard-layout, Standard Buffer Layout>>
-    alignment rules (internal merge request 3750).
-  * Relax non-strict line constraints in the <<primsrast-lines-basic>> and
-    <<primsrast-lines-bresenham>> sections (internal merge request 3792).
-  * Add missing `structextends` attribute to the
-    slink:VkPhysicalDevicePrivateDataFeaturesEXT definition in `vk.xml`
-    (internal merge request 3873).
-  * Move slink:VkImageFormatListCreateInfo valid usage statements to
-    flink:vkCreateImageView (internal merge request 3879).
-  * Update valid usage statements for slink:VkImageViewASTCDecodeModeEXT to
-    allow ASTC HDR formats (internal merge request 3881).
-  * Add missing extension dependency to
-    `<<VK_KHR_pipeline_executable_properties>>` definition in `vk.xml`
-    (internal merge request 3882).
-  * Require the <<features-customBorderColors>> feature be enabled when
-    using etext:VK_BORDER_COLOR_* in slink:VkSamplerCreateInfo (internal
-    merge request 3884).

------------------------------------------------------
-
-Change log for June 1, 2020 Vulkan 1.2.142 spec update:
-
-  * Update release number to 142 for this update.
-
-Github Issues:
-
-  * Add boilerplate descriptions of reserved bitmask types (public pull
-    request 1265).
-  * Move dynamic state valid usage statements from
-    slink:VkPipelineViewportExclusiveScissorStateCreateInfoNV and
-    VkPipelineViewportShadingRateImageStateCreateInfoNV to
-    slink:VkGraphicsPipelineCreateInfo, where they are testable, and make
-    corresponding tweaks in `vk.xml` (public pull request 1268).
-  * Add missing flink:vkDestroyPrivateDataSlotEXT explicit valid usage
-    statement (public pull request 1269).
-  * Cast arguments of dlink:VK_MAKE_VERSION macro to code:uint32_t to avoid
-    compiler warnings (public pull request 1279).
-
-Internal Issues:
-
-  * Update <<fundamentals-validusage-pNext, description of pname:pNext
-    chains>> to allow structures in the chain to be defined by either core
-    versions or extensions. Add the new term "`extending structure`" to the
-    glossary to describe such structures, and use it in place of "`extension
-    structure`". Update the style guide accordingly (internal issue 1083).
-  * Add a comment to the beginning of generated API includes showing which
-    combinations of API core versions and extensions provide that API, based
-    on the explicit requirements in the API XML. This does not yet document
-    enumerants introduced by extending a base enum type (internal issue
-    1431).
-  * Relax the restriction that slink:VkBufferImageCopy::pname:bufferOffset
-    must be a multiple of 4 for flink:vkCmdCopyBufferToImage and
-    flink:vkCmdCopyImageToBuffer when run on graphics or compute queues, but
-    not on transfer queues (internal issue 1701).
-  * Document the types of "`special use`" extensions in the new
-    <<extendingvulkan-compatibility-specialuse, Special Use Extensions>>
-    section, summarize special uses in the generated metadata for extension
-    appendices, and link back to the new section from each special use
-    extension (internal issue 1938).
-  * Clarify behavior of flink:vkGetDeferredOperationMaxConcurrencyKHR,
-    allowing it to return zero for competed operations (internal issue 2036).
-  * Allow flink:vkGetInstanceProcAddr to resolve itself with a `NULL`
-    pname:instance (internal issue 2057).
-  * Modify the valid usage statement ID assignment script to track a range
-    of unused IDs for each extension branch under development, instead of
-    only allowing VUID assignment in `master` and `devel` branches (internal
-    issue 2100).
-  * Add `selector` and `selection` attributes for unions in XML, to enable
-    automatic generation of validation code (internal issue 2140).
-  * Fix validity generator for stext:Vk*Flags types that are aliases,
-    correcting generation of implicit valid usage for
-    slink:VkAccelerationStructureInfoNV::pname:flags. Remove
-    `noautovalidity` attribute for this member, as well as the previously
-    written explicit valid usage (internal issue 2140).
-  * Fix description of slink:VkTextureLODGatherFormatPropertiesAMD (internal
-    issue 2189).
-  * Remove redundant text about variables being explicitly laid out in the
-    <<interfaces-resources-layout, Offset and Stride Assignment>> section
-    (internal merge request 3691).
-  * Fix conflicting slink:VkSamplerYcbcrConversionCreateInfo valid usage
-    statements (internal merge request 3716).
-  * Fix use of code:AHARDWAREBUFFER_USAGE_GPU_COLOR_OUTPUT to
-    code:AHARDWAREBUFFER_USAGE_GPU_FRAMEBUFFER in valid usage statement
-    02386 for slink:VkMemoryAllocateInfo (internal merge request 3808).
-  * Add missing `externsync` XML attributes for ftext:vkCmd* commands
-    (internal merge request 3825).
-  * Add missing `extends` attribute to
-    slink:VkDevicePrivateDataCreateInfoEXT XML (internal merge request
-    3834).
-  * Add code:RayGeometryIndexKHR to the `<<VK_KHR_ray_tracing>>` list of
-    built-in variables (internal merge request 3853).
-  * Restrict slink:VkBufferViewCreateInfo with ename:VK_WHOLE_SIZE, and
-    round down results of division in calculating the test in the
-    corresponding valid usage statements (internal merge request 3858).
-  * Miscellaneous cleanup and reorganization of synchronization language in
-    multiple places, and add the
-    <<synchronization-image-barrier-layout-transition-order>> section
-    (internal merge request 3861).
-  * Redefine ename:VK_PIPELINE_STAGE_TOP_OF_PIPE_BIT and
-    ename:VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT as pseudo-stages in multiple
-    places (internal merge request 3862).
-  * Reorganize some valid usage statements, especially but not limited to
-    stage mask parameters for slink:VkImageMemoryBarrier,
-    slink:VkPipelineStageFlags, flink:vkCmdPipelineBarrier,
-    flink:vkCmdResetEvent, flink:vkCmdSetEvent, flink:vkCmdWaitEvents,
-    flink:vkCmdWriteBufferMarkerAMD, and flink:vkCmdWriteTimestamp as common
-    valid usage statements, for future-proofing (internal merge requests
-    3864, 3865, 3866, 3867, 3868).

-
-Change log for May 15, 2020 Vulkan 1.2.141 spec update:
-
-  * Update release number to 141 for this update.
-  * *Note*: Using the default build options, specification outputs will now
-    be created in `gen/out/` instead of `out/`, and header files will be
-    created in `gen/include/vulkan` instead of `include/vulkan`. This can be
-    overridden using the `-genpath` option to the frontend scripts like
-    `makeAllExts` and `makeSpec`, or by specifying `GENERATED=*path*` on the
-    make command line when invoking it directly.
-
-Github Issues:
-
-  * Assign new elink:VkDriverId and elink:VkVendorId enums for Mesa (public
-    issue 1256).
-
-Internal Issues:

-    sentence fragment accidentally left over from an earlier merge conflict
-    resolution (internal issue 2158).
-  * Typo fixes for flink:vkGetRayTracingShaderGroupHandlesKHR and
-    flink:vkGetRayTracingCaptureReplayShaderGroupHandlesKHR valid usage
-    statements (internal merge request 3831).
-  * Add a `requiredBy` dictionary to the generated `vkapi.py` showing which
-    core versions or extensions require each API (internal merge request
-    3832).
-  * Allow specifying multiple API names for and tags in registry processing
-    scripts. Update the registry schema documentation accordingly, and
-    remove the redundant `xml_supported_name_of_api` method from the
-    VulkanConventions object (internal merge request 3836).
-  * Consolidate generated intermediate files and output documents into
-    $(GENERATED) directory, add -genpath option to scripts requiring them,
-    and modify Makefile accordingly. Add a new `makeSpec` script which
-    combines and extends the functionality of the `makeExt`, `makeKHR`, and
-    `makeAllExts` scripts (internal merge requests 3837, 3838, 3840, 3841).
-  * Add "`runtime`" to style guide and use that spelling consistently
-    (internal merge request 3843).

-Change log for May 3, 2020 Vulkan 1.2.140 spec update:
-
-  * Update release number to 140 for this update.
-
-Github Issues:
-
-  * Add `vk.xml` `noautovalidity` attribute to
-    flink:vkCmdBindTransformFeedbackBuffersEXT::pname:pSizes to cause change
-    in the generation of implicit valid usage statement for
-    pname:bindingCount (public issue 1227).
-  * Remove the special tokens (not part of the Vulkan API) suffixed with
-    etext:*_BEGIN_RANGE etext:*_END_RANGE, and etext:*_RANGE_SIZE from the
-    generated C headers, after consultation with downstream components and
-    ISVs and advanced warning to the developer community (public issue 1230,
-    internal issue 872).
-
-    *Note* if you absolutely require these tokens for some reason, you can
-    still build a version of the header which restores them. Edit
-    `scripts/genvk.py` to add the parameter `genEnumBeginEndRange = True` to
-    the `CGeneratorOptions` objects for the header file targets you want to
-    restore. See the version of `genvk.py` in the 1.2.139 spec update for an
-    example.
-  * Add valid usage statement to slink:VkApplicationInfo requiring that
-    pname:apiVersion be greater than or equal to dlink:VK_API_VERSION_1_0
-    (public pull request 1252).
-  * Add \<implicitexternsync> tags to `vk.xml` for flink:vkDestroyDevice
-    slink:VkQueue objects received from pname:device (public pull request
-    1255).
-  * Fix typo in slink:VkBufferMemoryBarrier language (public pull request
-    1257).
-
-Internal Issues:
-
-  * Automatically generate interface lists for extension appendices from
-    `vk.xml` using a new interface generator script, and update the style
-    guide's description of these appendices accordingly (internal issue
-    977, internal merge request 3819).
-  * Add transitive language to the <<formats-compatible-planes, Compatible
-    formats of planes of multi-planar formats>> section to pull in format
-    compatibility classes as well (internal issue 1615).
-  * Add valid usage statements to ftext:vkCmdBuildAccelerationStructure*KHR,
-    flink:vkCmdCopyAccelerationStructureToMemoryKHR, and
-    flink:vkCmdCopyMemoryToAccelerationStructureKHR for structure builds
-    bound to device memory (internal issue 2033).
-  * Don't generate etext:*_MAX_ENUM values in documentation generators,
-    since they're not part of the API, and only meaningful on compiled
-    headers (internal issue 2056).
-  * Remove special lifetime rules for pipelines in the
-    <<fundamentals-objectmodel-lifetime-cmdbuffers>> section (internal issue
-    2068).
-  * Improve valid usage statements for ftext:vkCmdTraceRays*, share more
-    common VUs between ftext:vkTraceRays*, and add ftext:vkCmdTracerays* VUs
-    for bound buffers. Improve documentation for the
-    pname:raygenShaderBindingOffset parameters and fork `NV` and `KHR` valid
-    usage statements, since the shader binding table is described
-    differently (internal issues 2075, 2136).
-  * Clarify lifetime of acceleration structure build inputs for
-    flink:vkCreateAccelerationStructureKHR (internal issue 2077).
-  * Add a Note to the <<framebuffer-blending, Blending>> section to stop
-    claiming that blending is ignored for all integer formats (internal
-    issue 2098).
-  * Mark handle parameters of some ftext:vkDestroy* commands as `optional`
-    and `externsync="true"` in `vk.xml` (internal issue 2129).
-  * Add missing `:refpage:` attributes for ray tracing common valid usage
-    statements (internal issue 2141).
-  * Redefine fragment to include the possibility of it covering multiple
-    pixels. This affects many parts of the specification including the
-    <<pipelines, Pipelines>>, <<primsrast, Rasterization>>, and <<fragops,
-    Fragment Operations>> chapters, the `<<VK_EXT_post_depth_coverage>>`
-    appendix, the `Coverage*` and `Sample Index` glossary entries, the
-    code:SampleId and code:SampleMask definitions in the
-    <<interfaces-builtin-variables, Built-In Variables>> section, and the
-    <<shaders-fragment-execution, Fragment Shader Execution>>,
-    <<shaders-fragment-earlytest, Early Fragment Tests>>, and
-    <<textures-texel-coordinate-systems, Texel Coordinate Systems>> sections
-    (internal merge request 3568).
-  * Refactor `scripts/genvk.py` script to specify generator and generator
-    options to the `Registry` object before loading XML. This allows
-    generator options to influence behavior such as reparenting enum
-    elements from feature/extension elmements to the enums they are being
-    added to, which is desirable for generating complete feature lists for
-    an extension or core version (internal merge request 3789).
-  * Raise a fatal error (instead of a warning) in `scripts/generator.py`
-    when two enumerants that are not aliased have the same value, so that CI
-    will fail (internal merge request 3807).
-  * Remove accidentally duplicated slink:VkSubpassDependency2 valid usage
-    statement 03093 (internal merge request 3826).
-
-New Extensions:
-
-  * `<<VK_EXT_private_data>>`
-  * `<<VK_EXT_custom_border_color>>`

-    (internal issue 1975).
-  * Add valid usage statement for flink:vkBindImageMemory2::pname:pBindInfos
-    to prevent binding disjoint memory twice (internal merge request 3696).
-  * Add valid usage statements to flink:vkGetBufferMemoryRequirements,
-    flink:vkGetImageMemoryRequirements, and
-    slink:VkBufferMemoryRequirementsInfo2 requiring that external Android
-    hardware buffers be bound to memory (internal merge request 3717).

-  * Allow slink:VkAccelerationStructureCreateInfoKHR::pname:maxGeometryCount
-    = 0, and clarify that exactly one of pname:compactedSize and
-    pname:maxGeometryCount must: be zero. (internal issue 2079).
-  * Add `allowduplicate` attribute to XML `type` tags to enable future
-    structures which can allow multiple copies of a structure in their
-    pname:pNext chain (internal issue 2090).
-  * Add the glossary term "`format features`", and make minor clarifications
-    to uses of this term in several places in the <<resources, Resource
-    Creation>> chapter and the
-    <<resources-sampler-ycbcr-conversion-format-features, Sampler Ycbcr
-    Conversion Format Features>> section (internal merge request 3727).
-  * Add a constraint to the <<memory-external-android-hardware-buffer,
-    Android Hardware Buffer>> section requiring that bound slink:VkImage or
-    slink:VkBuffer objects be created with the
-    ename:VK_EXTERNAL_MEMORY_HANDLE_TYPE_ANDROID_HARDWARE_BUFFER_BIT_ANDROID
-    flag set, and corresponding valid usage statements to

-    flink:vkBindImageMemory, and slink:VkBindImageMemoryInfo (internal merge
-    request 3732).
-  * Fix pname:memoryTypes ordering description for device coherent memory
-    (ename:VK_MEMORY_PROPERTY_DEVICE_UNCACHED_BIT_AMD) in the

-    <<memory-external-android-hardware-buffer-usage, AHardwareBuffer Usage
-    Equivalence>> table, and add
-    ename:VK_IMAGE_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT flag for this case
-    (internal merge request 3741).
-  * Add more references to `NV` and `KHR` ray tracing pipelines in
-    discussions of creating pipelines, or generalize text so they need not
-    all be mentioned by name (internal merge request 3743).
-  * Allow *ShaderCallKHR* memory scope in ray tracing shaders, in the

-Change log for April 06, 2020 Vulkan 1.2.137 spec update:
-
-  * Update release number to 137 for this update.
-
-Github Issues:
-
-  * Incorporate several changes to the specification build process and HTML
-    load-time scripts which pre-render KaTeX math, pre-fetch fonts, and
-    perform several other optimizations which can significantly improve load
-    time for the single-page HTML specification. In our internal evaluation
-    these changes appear to primarily help when using Chrome or Chromium,
-    with smaller improvements for Firefox and Safari. Speedups seem more
-    significant on Linux, Windows, and Android platforms, while MacOS
-    browsers may benefit less (public pull requests 702, 704, and 708).
-  * Clarify that code:OpVariable is decorated with code:Location, not
-    code:OpTypeStruct in the <<interfaces-iointerfaces-locations, Location
-    Assignment>> section (public issue 1203).
-  * Add a NOTE about the WSI origin location in the description of
-    flink:vkQueuePresentKHR (public pull request 1208).
-  * Add the `null-terminated` attribute to
-    slink:VkPerformanceValueDataINTEL::pname:valueString in `vk.xml` (public
-    pull request 1209).

-    slink:VkPhysicalDeviceVulkan12Properties structures as `returnedonly` in
-    `vk.xml` (public pull request 1210).
-  * Create explicit valid usage statements from text in the description of
-    slink:VkValidationFeaturesEXT (public pull request 1212).
-  * Update style guide to add "`user`" to the list of words *not* to use,
-    instead recommending "`application`" (public pull request 1213).
-  * Fix typos where `ext:` was used in the style guide instead of the new
-    `apiext:` asciidoctor macro (public pull request 1214).
-  * Miscellaneous minor markup and editing fixes (public pull request 1215).
-  * Remove etext:KHR from promoted ename:VK_MAX_DRIVER_NAME_SIZE in the
-    description of slink:VkPhysicalDeviceDriverProperties (public pull
-    request 1218).
-  * Correct use of `NULL` to dlink:VK_NULL_HANDLE in the
-    <<acceleration-structure-inactive-prims, Inactive Primitives and
-    Instances>> section (public pull request 1219).
-  * Remove trailing periods on valid usage statement text, as required by
-    the style guide, and add `scripts/deperiodize_vuids.py` to do this in
-    the future if needed (public pull request 1220).
-
-Internal Issues:
-

-  * Describe the meaning of code:Device for the `<<VK_KHR_shader_clock>>`
-    extension in the <<shaders-scope-device, Device>>,
-    <<shaders-scope-queue-family, Queue Family>>, and
-    <<shaders-scope-command, Command>> sections of the shader
-    <<shaders-scope, Scope>> section (internal issue 1955).
-  * Allow slink:VkDebugUtilsObjectNameInfoEXT::pname:pObjectName to be
-    either NULL or an empty string to remove a previously set name (internal
-    issue #2019).
-  * Add missing VK_ERROR_OUT_OF_HOST_MEMORY error code in `vk.xml` for
-    flink:vkEnumerateInstanceVersion (internal issue 2029).
-  * Require code:R32i or code:R32ui image format for
-    code:OpImageTexelPointer atomic operations in the
-    <<spirvenv-module-validation, Validation Rules within a Module>> section
-    (internal issue 2049).
-  * Remove the `<pattern>` element from images used in the specification, to
-    avoid complaints from prawn-svg during PDF spec builds (internal issue
-    2053).
-  * Clarify usable sample counts for empty subpasses in the
-    <<features-variableMultisampleRate>> section and the related
-    flink:vkCmdBindPipeline valid usage statement, as well as in the

-  * Add an alias from the old ename:VK_ANDROID_NATIVE_BUFFER_EXTENSION_NAME
-    token (internal merge request 3697).
-  * Add `scripts/compImages.sh` to compare all images in two git branches of
-    the specification (internal merge request 3699).
-  * Improve valid usage statements for `<<VK_NV_device_generated_commands>>`
-    in flink:vkCmdExecuteGeneratedCommandsNV,
-    slink:VkGeneratedCommandsInfoNV,
-    flink:vkCmdPreprocessGeneratedCommandsNV,
-    slink:VkIndirectCommandsStreamNV, slink:VkIndirectCommandsLayoutTokenNV
-    and slink:VkGraphicsPipelineCreateInfo (internal merge request 3702).
-  * Clarify differences between `<<VK_NV_ray_tracing>>` and
-    `<<VK_KHR_ray_tracing>>` for
-    slink:VkPipelineCreationFeedbackCreateInfoEXT pipeline creation,
-    pname:shaderGroupHandleSize and pname:maxRecursionDepth limit
-    requirement differences, and detangle `SPV_KHR/NV_ray_tracing` in the
-    <<spirvenv-capabilities-table, List of SPIR-V Capabilities and enabling
-    features or extensions>> (internal merge request 3710).
-  * Add flink:vkGetImageViewAddressNVX and

-    3728).
-  * Add flink:vkGetBufferMemoryRequirements2 and
-    flink:vkGetImageMemoryRequirements2 to the commands for which the
-    implementation makes guarantees about certain properties of the memory
-    requirements in the <<resources-association, Resource Memory
-    Association>> section, following the description of
-    slink:VkMemoryRequirements (internal merge request 3730).
-  * Add valid usage statements for
-    `<<VK_ANDROID_external_memory_android_hardware_buffer>>` (internal merge
-    request 3731).
-  * Add requirements on the
-    slink:VkAccelerationStructureMemoryRequirementsInfoKHR acceleration

------------------------------------------------------
-
-Change log for March 24, 2020 Vulkan 1.2.136 spec update:
-
-  * Update release number to 136 for this update.
-
-Github Issues:
-
-  * Generate per-extension refpages from the extension appendices in the
-    specification instead of the old, minimal generated refpages, and update
-    the registry index to point to these refpages instead of the
-    specification (public issue 1195, internal issue 1999).
-  * Rename ename:VK_STRUCTURE_TYPE_QUERY_POOL_CREATE_INFO_INTEL to
-    ename:VK_STRUCTURE_TYPE_QUERY_POOL_PERFORMANCE_QUERY_CREATE_INFO_INTEL
-    to match the similar renaming of sname:VkQueryPoolCreateInfoINTEL to
-    slink:VkQueryPoolPerformanceQueryCreateInfoINTEL (public issue 1207,
-    internal issue 2048).
-
-Internal Issues:
-
-  * Add a new <<resources-sampler-ycbcr-conversion-format-features, Sampler
-    Ycbcr Conversion Format Features>> section, and update
-    elink:VkFormatFeatureFlagBits and valid usage statements for
-    slink:VkSamplerCreateInfo and slink:VkSamplerYcbcrConversionCreateInfo
-    to refer to it (internal issue 1963).
-  * Comment out reserved but unused ename:VK_ACCESS_RESERVED_31_BIT_KHR to
-    avoid generator script warnings (internal issue 2016).
-  * Fix some `<<VK_KHR_ray_tracing>>` valid usage IDs that were broken in
-    the 1.2.135 update (internal issue 2044).
-  * Remove `const` qualifier from
-    sname:VkPhysicalDeviceDeviceGeneratedCommandsPropertiesNV::pname:pNext
-    in `vk.xml` (internal issue 2047).
-  * Remove `flowRoot` elements supported only by Inkscape from some of the
-    images, and update a couple to 96 DPI from 90 DPI due to current
-    Inkscape's insistence. This reduces warnings from prawn-svg during PDF
-    builds (internal issue 2053).
-  * Remove reference in the <<devsandqueues-lost-device, Lost Device>>
-    section to a non-existent list of functions returning
-    ename:VK_ERROR_DEVICE_LOST (internal merge request 3667).
-  * Add valid usage statements to slink:VkImageViewCreateInfo for cube and
-    cube array image view (internal merge request 3682).
-  * Remove redundant valid usage statement 00228 from flink:vkCmdBlitImage
-    (internal merge request 3684).
-  * Document the Khronos-provided Docker image, whose use is recommended
-    when building documents and generated files from this repository
-    (internal merge request 3686).
-  * Rename ename:VK_PIPELINE_COMPILE_REQUIRED_EXT from
-    ename:VK_ERROR_PIPELINE_COMPILE_REQUIRED_EXT and add an alias from the
-    old name, since it is not actually an error code. Add it to the
-    `successcodes` attributes of appropriate commands in `vk.xml` (internal
-    merge request 3687).

-    pname:pNext chain; slink:VkExportFenceWin32HandleInfoKHR on
-    slink:VkExportFenceCreateInfo in the slink:VkFenceCreateInfo pname:pNext
-    chain; and slink:VkExportSemaphoreWin32HandleInfoKHR on
-    slink:VkExportSemaphoreCreateInfo in the slink:VkSemaphoreCreateInfo
-    pname:pNext chain (public issue 1095).
-  * Update the <<spirvenv-module-validation, Validation Rules within a
-    Module>> section of the SPIR-V environment appendix to allow the
-    code:PhysicalStorageBuffer64 addressing model (public issue 1199).
-  * Fix markup in parameters section of
-    flink:vkGetPhysicalDeviceXcbPresentationSupportKHR (public pull request
-    1201).
-  * Amend rules in the <<extensions-vendor-id, Registering a Vendor ID with
-    Khronos>> section of the style guide to allow other Khronos APIs such as
-    OpenCL to reserve vendor IDs here so they can be shared with those APIs
-    (public KhronosGroup/OpenCL-Docs pull request 203).
-
-Internal Issues:
-
-  * Clarify layer loading order for slink:VkInstanceCreateInfo and in the
-    <<extendingvulkan-layers, Layers>> chapter following the specification
-    of slink:VkLayerProperties (internal issue 1986).
-  * Simplify markup for SPIR-V versions required by different Vulkan
-    versions in the <<spirvenv, Vulkan Environment for SPIR-V>> appendix
-    (internal issue 2011).
-  * Rename sname:VkQueryPoolCreateInfoINTEL to
-    slink:VkQueryPoolPerformanceQueryCreateInfoINTEL in the
-    `<<VK_INTEL_performance_query>>` extension (internal issue 2022).
-  * Add ename:VK_VALIDATION_FEATURE_ENABLE_DEBUG_PRINTF_EXT to
-    elink:VkValidationFeatureEnableEXT to specify that layers will process
-    code:debugPrintfEXT operations (internal issue 2023).
-  * Fix conflicting language in slink:VkSamplerYcbcrConversionCreateInfo
-    valid usage statement 01653 (internal merge request 3629).
-  * Add missing valid usage statement for slink:VkSparseImageMemoryBindInfo
-    to require slink:VkImage objects created with the
-    ename:VK_IMAGE_CREATE_SPARSE_RESIDENCY_BIT flag set (internal merge
-    request 3633).
-  * Remove redundant valid usage statement 00122 from flink:vkCmdCopyImage
-    (internal merge request 3643).
-  * Fix several places where `VULKAN_1_1` was used in asciidoctor
-    conditional markup instead of `VK_VULKAN_1_1` (internal merge request
-    3654).
-  * Fix conditional markup around slink:VkImageViewCreateInfo valid usage
-    statement 01018 to ensure it doesn't overlap a similar valid usage
-    statement written for another combination of enabled extensions and
-    versions (internal merge request 3655).
-  * Remove redundant valid usage statement from flink:vkCmdCopyImage that
-    was already covered by statements for slink:VkImageCopy. Eventually this
-    will be inverted so the statements are located with flink:vkCmdCopyImage
-    but that requires more work and is deferred (internal merge request
-    3656).
-  * Clarify wording of slink:VkImageMemoryBarrier valid usage statement
-    01671 and add a missing statement (internal merge request 3657).
-  * Minor fixes to the style guide to bring it up to date with respect to
-    the asciidoctor client, assignment of valid usage ID tags, and proper
-    placement of valid usage statements (internal merge request 3662).
-  * Add missing valid usage statements to slink:VkSubpassDescription2 based
-    on comparable statements for slink:VkSubpassDescription (internal merge
-    request 3663).
-
-New Extensions
-
-  * Ray Tracing package of extensions, including
-  ** `<<VK_KHR_deferred_host_operations>>`
-  ** `<<VK_KHR_pipeline_library>>`
-  ** `<<VK_KHR_ray_tracing>>`
-  * `<<VK_EXT_pipeline_creation_cache_control>>`

-    request 3561).
-  * Add valid usage statements to slink:VkCommandPoolCreateInfo and

-Change log for September 8, 2019 Vulkan 1.1.122 spec update:
-
-  * Update release number to 122.
-
-Internal Issues:
-
-  * Add style guide language on not using standalone `+` signs (internal
-    issue 736); not using leading whitespace for markup (internal issue
-    747); and on keeping descriptions of a single API in a contiguous block
-    of markup (internal issue 949), and apply them to the specification.
-  * Add a glossary definition of "`constant integral expression`", pointing
-    to the SPIR-V "`constant instruction`" definition (internal issue 1225).
-  * Many minor edits to improve writing style consistency and capture
-    additional style guidelines (internal issue 1553).
-  * Clarify that <<fragops-depth-write, depth writes are not performed>> if
-    there is no depth framebuffer attachment (internal issue 1771).
-  * Allow implementations to use rectangular line style of interpolation for
-    <<primsrast-lines-bresenham, wide Bresenham lines>>, though replicating
-    attributes is still preferred. Clarify that code:FragCoord is not
-    replicated (internal issue 1772).
-  * Resolve a contradiction in valid usage statements for
-    slink:VkImageCreateInfo and slink:VkImageStencilUsageCreateInfoEXT
-    (internal issue 1773).
-  * Add style guide discussion of markup for indented equations, and use
-    markup workaround for asciidoctor 2 compatibility (internal issue 1793).
-  * Deprecate the `<<VK_EXT_validation_flags>>` extension in `vk.xml` and
-    the extension appendix (internal issue 1801).
-  * Add a new checker script `scripts/xml_consistency.py`. This is not
-    currently run as part of internal CI (internal merge request 3285).
-  * Correct "`an`" -> "`a`" prepositions where needed (internal merge
-    request 3334).
-  * Clarify that the <<features-uniformBufferStandardLayout,
-    pname:uniformBufferStandardLayout>> feature is only required when the
-    extension defining it is supported (internal merge request 3341).
-  * Bring scripts into closer sync with OpenXR, mainly through conversion of

-
-Github Issues:
-
-  * Add missing `structextends` attribute in `vk.xml` for
-    slink:VkPhysicalDevicePipelineExecutablePropertiesFeaturesKHR (public
-    issue 1018).
-  * Change attributes of flink:vkCmdCopyAccelerationStructureNV,
-    flink:vkCmdWriteAccelerationStructuresPropertiesNV,
-    flink:vkCmdBuildAccelerationStructureNV, and flink:vkCmdTraceRaysNV to
-    require that these commands execute outside renderpasses (public issue
-    1021).
-  * Add an issue to the `<<VK_EXT_buffer_device_address>>` appendix
-    discussing the introduction of new names and aliasing by equivalent old
-    names (public pull request 1024).
-
-Internal Issues:
-
-  * Protect the `VK_KHR_sampler_mirror_clamp_to_edge` extension with
-    asciidoctor conditionals, and remove it from the core-only specification
-    builds, where it had previously been force-included in the Makefile. It
-    is now treated like any other extension (internal issue 1776).
-  * Edit some asciidoctor anchor names starting with `features-features-` to
-    just start with `features-`, since the old chapters was split into 3
-    pieces. There are still some mild naming inconsistencies with anchors
-    which may be addressed in the future (internal issue 1792).
-  * Add `KHR` alias for the non-suffixed extension token
-    ename:VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE, for compatibility
-    with naming rules for extensions (internal issue 1796).
-  * Clarify requirements for external memory in NOTEs for
-    sname:VkExternalMemoryBufferCreateInfo, and valid usage statements for
-    flink:vkBindBufferMemory, slink:VkBindBufferMemoryInfo,
-    flink:vkBindImageMemory, and slink:VkBindImageMemoryInfo (internal merge
-    request 3301).
-  * Make extension version numbers in `vk.xml` and extension appendices
-    consistent. In a few cases, we could not recover history at this
-    granularity, and left the summary of a version's change undefined
-    (internal merge request 3323).
-  * Fix invocation of `CodeInlineMacro` in the Ruby extension backing the
-    `code:` macro, which was delegating to the wrong base class (internal
-    merge request 3331).
-  * Modify `reg.py` to do a better job of recognizing equivalent <enum>
-    definitions.
-  * Add a `sortorder` attribute to XML feature and extension tags.

-    for flink:vkQueuePresentKHR, flink:vkQueueSubmit, and
-    flink:vkQueueBindSparse (internal issue 1774).
-  * Add `<<VK_EXT_validation_features>>` flag to enable best practices
-    checks, which will soon be available in the validation layer (internal
-    issue 1779).
-  * Specify allowed characters for VUID tag name components in the style
-    guide (internal issue 1788).
-  * Update links to SPIR-V extension specifications, and parameterize their
-    markup in case the URLs change in the future (internal issue 1797).
-  * Fix an off-by-one error in the valid usage statement for
-    slink:VkPipelineExecutableInfoKHR (internal merge request 3303).
-  * Clean up markup indentation not matching the style guide (internal merge
-    request 3314).
-  * Minor script updates to allow refpage aliases, generate a dynamic TOC
-    for refpages, generate Apache rewrite rules for aliases, open external
-    links from refpages in a new window, and synchronize with the OpenCL
-    scripts. This will shortly enable a paned navigation setup for refpages,
-    similar to the OpenCL 2.2 refpages (internal merge request 3322).
-  * Script updates to add tests to the checker, refactor and reformat code,
-    generate better text for some valid usage statements, use more Pythonic
-    idioms, and synchronize with the OpenXR scripts (internal merge request
-    3239).
-  * Script updates and minor fixes in spec language to not raise checker
-    errors for refpage markup of pages not existing in the API, such as
-    VKAPI_NO_STDINT_H. Remove corresponding suppression of some
-    check_spec_links.py tests from .gitlab-ci.yml and 'allchecks' target
-    (internal merge request 3315).

-    slink:VkRenderPassBeginInfo when the `<<VK_KHR_imageless_framebuffer>>`
-    extension is enabled (public issue 998).
-  * Clarify the subpass dependency requirement in the

-
-  * Happy 50th Lunar Landing Day!
-  * Update release number to 116.
-
-Internal Issues:
-
-  * Clarify that flink:vkCmdBeginQuery is the same as
-    flink:vkCmdBeginQueryIndexEXT with index = 0, and that
-    flink:vkCmdEndQuery is the same as flink:vkCmdEndQueryIndexEXT with
-    index = 0 (internal issue 1735).
-  * Clarify that when copying the depth aspect between buffers and images
-    via slink:VkBufferImage Copy, the depth values in buffer memory must be
-    in range if the `<<VK_EXT_depth_range_unrestricted>>` extension is not
-    enabled (internal issue 1737).
-  * Minor language tweaks in the <<spirvenv-module-validation, Validation
-    Rules within a Module>> section (internal issue 1744).
-  * Change the slink:VkPhysicalDeviceFloatControlsPropertiesKHR structure in
-    the `<<VK_KHR_shader_controls>>` extension. This is a rare case of
-    breaking the interface of an existing extension to acknowledge the
-    reality of divergent vendor implementations that could not be described
-    properly otherwise, and the breaking change is considered acceptable
-    given the expected low use of the extension (internal issue 1734).
-    Specific changes:
-  ** Added the slink:VkShaderFloatControlsIndependenceKHR enumeration to
-     describe the three possible behaviors.
-  ** Renamed pname:separateDenormSettings to
-     pname:denormBehaviorIndependence.

-  * Add valid usage statements to slink:VkWriteDescriptorSet and
-    slink:VkCopyDescriptorSet specifying that updating immutable descriptors
-    with ename:VK_DESCRIPTOR_TYPE_SAMPLER is invalid, and that updating
-    ename:VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER ignores the update's
-    samplers (public issue 985).
-  * Document that the `manhtmlpages` target requires building with all
-    extensions enabled, in `BUILD.adoc` (public issue 992).

-    usage in the <<textures-gather, Texel Gathering>> and
-    <<spirvenv-module-validation, Validation Rules within a Module>>
-    sections, and for the <<limits-minTexelGatherOffset>> and
-    <<limits-maxTexelGatherOffset>> limits (internal issue 1723).
-  * Require code:code:OpGroupNonUniformBroadcast to take a constant `Id`
-    operand in the <<spirvenv-module-validation, Validation Rules within a
-    Module>> sections (internal issue 1726).
-  * Note that the swapchain specified in slink:VkImageSwapchainCreateInfoKHR
-    when creating an image must match the one specified in
-    slink:VkBindImageMemorySwapchainInfoKHR when binding memory to the image
-    (internal issue 1729).
-  * Remove stext:KHR suffix from some structure cross-references that were
-    promoted to Vulkan 1.1 (internal issue 1730).
-  * Fix structure name in `structextends` attribute for
-    slink:VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT in `vk.xml`

-    issue 1639).
-  * Remove the "`block`" language around <<features-robustBufferAccess,
-    vectorizing and robust buffer access>> (internal issue 1642).
-  * Allow code:OpTypeImageFormat == code:Unknown for input attachments in
-    the <<interfaces-resources-descset, Descriptor Set Interface>> section
-    (internal issue 1645).
-  * Fix asciidoctor conditionals around
-    ename:VK_ERROR_FULL_SCREEN_EXCLUSIVE_MODE_LOST_EXT in the
-    <<fundamentals-errorcodes>> section (internal issue 1679).
-  * Remove error codes from `vk.xml` for
-    flink:vkUninitializePerformanceApiINTEL, which has a `void` return type
-    (internal issue 1704).
-  * Various subgroup-related fixes in the <<spirvenv-capabilities,
-    Capabilities>>, <<shaders-subgroup-arithmetic, Arithmetic Subgroup
-    Operations>>, <<shaders-subgroup-clustered, Clustered Subgroup
-    Operations>>, and <<shaders-subgroup-partitioned, Partitioned Subgroup

-Change log for May 13, 2019 Vulkan 1.1.108 spec update:
-
-  * Update release number to 108.
-
-Internal Issues:
-
-  * Clarify that only external resources can be bound to external memory in
-    valid usage statements for flink:vkBindBufferMemory,
-    flink:vkBindImageMemory, slink:VkSparseMemoryBind, and
-    slink:VkSparseImageMemoryBind (internal issue 1496).
-  * Move all `vk.xml`requirements for

-  * Fix typos in the description of slink:VkImageViewCreateInfo (internal
-    issue 1661).
-  * Modify valid usage statements for slink:VkImageViewCreateInfo to fix the
-    description about the restriction for pname:baseArrayLayer and
-    pname:layerCount from pname:extent.depth to the depth of mipmap level
-    while creating a 2D array image view on a 3D image.
-  * Forbid structures that contain opaque types (images or samplers) in the

-
-Change log for April 16, 2019 Vulkan 1.1.107 spec update:
-
-  * Update release number to 107.
-
-Public Issues:
-
-  * Fix revision date for the `<<VK_AMD_gpu_shader_half_float>>` appendix
-    (public issue 617).
-  * Make <<synchronization-pipeline-barriers-subpass-self-dependencies,
-    subpass self-dependencies>> less restrictive (public issue 777).
-  * Fix the `<<VK_EXT_full_screen_exclusive>>` dependency on
-    `<<VK_KHR_win32_surface>>` in `vk.xml` (public pull request 849).
-  * Remove single-page (`apispec.html`) refpage sub-targets from the
-    Makefile `allman` target and the build instructions. The target is still
-    present in the Makefile, but we have not been actively maintaining the
-    single-page document and do not promise it will work. The full
-    Specification and the individual API reference pages are what we support
-    and publish at present (public issue 949).
-
-Internal Issues:
-
-  * De-duplicate common valid usage statements shared by multiple commands
-    or structures by using asciidoctor includes and dynamically assigning
-    part of the valid usage ID based on which command or structure they're
-    being applied to (internal issue 779).
-  * Add reference pages for constructs not part of the formal API, such as
-    platform calling convention macros, and script changes supporting them
-    This required suppressing some check_spec_links warning classes in order
-    to pass CI, until a more sophisticated fix can be done (internal issue
-    888).
-  * Change math notation for the elink:VkPrimitiveTopology descriptions to
-    use short forms `v` and `p` instead of `vertex` and `primitive`,
-    increasing legibility (internal issue 1611).
-  * Rewrite generated file includes relative to a globally specified path,
-    fixing some issues with refpage generation (internal issue 1630).
-  * Update contributor list for `<<VK_EXT_calibrated_timestamps>>`.
-  * Fix use of pathlin in `scripts/generator.py` so the script will work on
-    Windows under Python 3.5 (internal merge request 3107).
-  * Add missing conditionals around the
-    <<descriptorsets-accelerationstructure, Acceleration Structure>>
-    section (internal merge request 3108).
-  * More script synchronization with OpenXR spec repository (internal merge
-    request 3109).
-  * Mark the `<<VK_AMD_gpu_shader_half_float>>` and
-    `<<VK_AMD_gpu_shader_int16>>` extensions as deprecated in `vk.xml` and
-    the corresponding extension appendices (internal merge request 3112).

-
-Change log for April 7, 2019 Vulkan 1.1.106 spec update:
-
-  * Update release number to 106.
-
-Public Issues:
-
-  * Add searchbox and generate search index for the chunked HTML target.
-    Note that doing this requires several new toolchain components to build
-    the `chunked` target (public issue 578 / internal issue 1352).
-  * Remove descriptions of flink:vkCreateSampler sampler constraints which
-    were repeated in the valid usage statements (public pull request 648).
-  * Fix sense of conditional around a valid usage statement in the
-    <<copies>> chapter (public issue 942).
-
-Internal Issues:
-
-  * Add missing pname:extent.width and pname:extent.height valid usage
-    statements for flink:vkCmdClearAttachments (internal issue 1583).
-  * Fix some inconsistencies in structures and corresponding pname:sType
-    enumerant names by renaming
-    sname:VkPhysicalDeviceShaderDrawParameterFeatures ->
-    slink:slink:VkPhysicalDeviceShaderDrawParametersFeatures;
-    sname:VkPhysicalDeviceVariablePointerFeatures ->
-    slink:VkPhysicalDeviceVariablePointerFeatures;
-    sname:VkPhysicalDeviceVariablePointerFeaturesKHR ->
-    slink:VkPhysicalDeviceVariablePointerFeaturesKHR;
-    sname:VkPhysicalDeviceBufferAddressFeaturesEXT ->
-    slink:VkPhysicalDeviceBufferDeviceAddressFeaturesEXT;
-    etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_DRAW_PARAMETER_FEATURES
-    ->
-    ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_DRAW_PARAMETERS_FEATURES;
-    etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTER_FEATURES ->
-    ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTERS_FEATURES;
-    etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTER_FEATURES_KHR ->
-    ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTERS_FEATURES_KHR;
-    and etext:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_ADDRESS_FEATURES_EXT
-    ->
-    ename:VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_DEVICE_ADDRESS_FEATURES_EXT.
-    The old names are still available as aliases for backwards
-    compatibility. This change required introducing valid XML markup which
-    externally written XML processing scripts may need to be modified to
-    accomodate, to support multiple aliases of a single command or token
-    name (internal issue 1592).
-  * Add slink:VkDevice as the first parameter to flink:vkSetLocalDimmingAMD
-    (internal issue 1618).
-  * Improve CI header compilation tests to test all Vulkan platform
-    includes, using fake platform headers where needed, and change the
-    `allchecks` Makefile target to use the more comprehensive
-    `check_spec_links.py` script instead of the retired `checkinc` and
-    `checklinks` targets.
-  * Move descriptions of the ASTC compressed texture decode mode from the
-    <<appendix-compressedtex-astc,appendix>> to the recently updated
-    external Khronos Data Format Specification.
-  * Fix minor markup and spelling issues in the `VK_NV_ray_tracing`
-    extension.

-
-Change log for March 18, 2019 Vulkan 1.1.104 spec update:
-
-  * Update release number to 104.
-
-Public Issues:
-
-  * Remove the incorrect line from "`Initial`" to "`Invalid`" state in the
-    <<commandbuffer-lifecycle-diagram, Lifecycle of a command buffer>>
-    diagram (public issue 881).
-  * Add Fuchsia platform to <<boilerplate-wsi-header-table, Window System
-    Extensions and Headers>> table (public pull request 933).
-  * Change the type of
-    slink:VkBufferDeviceAddressCreateInfoEXT::pname:deviceAddress from
-    basetype:VkDeviceSize to basetype:VkDeviceAddress. These are both
-    typedefs of code:uint64_t, so it is an ABI-compatible change (public
-    issue 934).
-
-Internal Issues:
-
-  * Remove generated header files and update the CI tests to build a copy of
-    the headers for use by the hpp-generate / hpp-compile CI stages. Targets
-    to generate the headers will not be removed, but keeping these generated
-    files in the repository increased the frequency of conflicts between
-    branches when merging to master (internal issue 745).
-  * Reword "`undefined: behavior if *action*" to "`must: not do *action*`"
-    in the places the old terminology was used, and add a new
-    <<writing-undefined, Describing Undefined Behavior>> section of the
-    style guide to explain how to write such language in the future
-    (internal issue 1579).
-  * Move almost all Python scripts into the toplevel `scripts/` directory.
-    Apply extensive internal edits to clean up and simplify the scripts, and
-    try to follow PEP8 guidelines. Generalize the scripts with the use of a
-    Conventions object controlling many aspects of output generation, to
-    enable their use in other Khronos projects with similar requirements.
-    Autogenerate extension interface refpages (these are experimental and
-    may be retired going forward).

-Change log for March 11, 2019 Vulkan 1.1.103 spec update:
-
-  * Update release number to 103.
-
-Public Issues:
-
-  * Remove (unnecessary) scoped modification order case from the memory
-    model <<memory-model-location-ordered, location-ordered>> definition
-    (public pull request 924).
-  * Add an <<memory-model-acyclicity, acyclicity>> axiom to the memory model
-    (public pull request 927).
-
-Internal Issues:
-
-  * Fix reversed logic of slink:VkFormatProperties discussion of multi-plane
-    formats and ename:VK_FORMAT_FEATURE_DISJOINT_BIT (internal issue 1493).
-  * Clarify how slink:VkImageStencilUsageCreateInfoEXT works, including new
-    valid usage statements for flink:vkCmdClearDepthStencilImage, and the
-    <<copies, Common Operation>> section of the Copy Commands chapter
-    (internal issue 1565).
-  * Update <<spirvenv-precision-operation, Precision and Operation of SPIR-V
-    Instructions>> section to require that denorms be preserved by several
-    instructions that don't perform any mathematical operations (internal
-    issue 1584).
-  * Remove duplicate valid usage statement from flink:vkAcquireNextImageKHR
-    (internal merge request 3062).
-
------------------------------------------------------
-
-Change log for March 3, 2019 Vulkan 1.1.102 spec update:
-
-  * Update release number to 102.
-
-Public Issues:
-
-  * Simplify flink:vkGetImageMemoryRequirements constraint for
-    ename:VK_MEMORY_PROPERTY_LAZILY_ALLOCATED_BIT (public pull request 817).
-  * Fix typo in markup of the <<textures-texel-coordinate-systems-diagrams,
-    Texel Coordinate Systems, Corner Sampling>> image that was generating
-    complaints from chunked HTML output generation (public pull request
-    928).
-
-Internal Issues:
-
-  * Split the old <<features, Features>> chapter into four chapters:
-    <<features, Features>>, <<limits, Limits>>, <<formats, Formats>>, and
-    <<capabilities, Capabilities>>, with minor edits to the introductory
-    paragraph of each chapter. Anchor names in these chapters were changed,
-    with corresponding effects to xrefs to these anchors elsewhere in spec
-    markup . The purpose is to make the chunked HTML spec output load faster
-    on what was previously a single, gigantic chapter (internal issue 1554).
-  * Add ename:VK_PIPELINE_STAGE_RAY_TRACING_SHADER_BIT_NV, to the supported
-    pipeline stages for ename:VK_ACCESS_UNIFORM_READ,
-    ename:VK_ACCESS_SHADER_READ, and ename:VK_ACCESS_SHADER_WRITE in the
-    <<synchronization-access-types-supported>> table.
-  * Correct legal name of Google, LLC in vk.xml <tags> section and a
-    copyright statement.
-  * Clarify that Vulkan treats the Android
-    code:AHARDWAREBUFFER_FORMAT_R8G8B8X8_UNORM format as RGBA, and the
-    application is responsible for forcing the X/A component to be read as
-    1.0, in the <<memory-external-android-hardware-buffer-formats>> table.
-  * Clarify the vertex order of various primitive topologies, and define the
-    order of transform feedback vertex capture based on that. This involves
-    a lot of refactoring and cleanup in the <<drawing-primitive-topologies,
-    Primitive Topologies>>, <<geometry-input, Geometry Shader Input
-    Primitives>> sections, and <<vertexpostproc-transform-feedback Transform
-    Feedback>> sections, and numerous places in the <<tessellation>>

-Change log for February 17, 2019 Vulkan 1.1.101 spec update:
-
-  * Update release number to 101.
-
-Public Issues:
-
-  * Make clear that memory types for imported host memory must be host
-    visible in slink:VkMemoryHostPointerPropertiesEXT.txt (public issue
-    897).
-  * Make <<interfaces-resources-layout, WARNING block>> into a NOTE block,
-    per the styleguide (public pull request 916).
-
-Internal Issues:
-
-  * Make <<textures-output-format-conversion, computation of derivatives in
-    non-uniform flow control>> have undefined behavior (internal issue
-    1367).
-  * Make behavior, not just values, undefined for
-    <<textures-layout-validation, reads from inconsistent YCbCr layouts>>
-    (internal issue 1366).
-  * Consolidate version and extension behavior documentation in the
-    <<extended-functionality, Extended Functionality>> appendix, While a
-    great deal of text was moved from other parts of the Specification into
-    the appendix, this just serves to simplify and make consistent
-    discussions of versions and extensions (internal issue 1473).
-  * Add limits for slink:VkPhysicalDeviceRayTracingPropertiesNV in the
-    <<features-limits-types, Required Limit Types>> and
-    <<features-limits-required, Required Limits>> tables (internal issue
-    1511).
-  * Disallow <<memory-protected-memory, indirect calls within protected
-    command buffers>> by adding valid usage statements for the related
-    indirect dispatch and draw commands (internal issue 1513).
-  * Add valid usage stataements to slink:VkGraphicsPipelineCreateInfo,
-    slink:VkSubpassDescription, slink:VkSubpassDescription2KHR,
-    slink:VkSubpassDescriptionDepthStencilResolveKHR, and
-    slink:VkImageViewCreateInfo preventing the creation of a renderpass with
-    attachments in formats that are not supported for rendering (internal
-    issue 1552).
-  * Qualify valid usage statements for
-    slink:VkAttachmentReference::pname:layout parameter so restrictions only
-    apply if an attachment is ename:VK_ATTACHMENT_UNUSED (internal issue
-    1561).
-  * Add valid usage statement for flink:vkCmdDrawIndirectByteCountEXT
-    restricting pname:vertexStride to be positive (internal issue 1566).
-  * Make the `VK_EXT_sample_locations` extension depend on
-    `VK_KHR_get_physical_device_properties2` in `vk.xml`.
-  * Rearrange and simplify the <<interfaces-resources-layout, block layout
-    rules>>.

-New Extensions:
-
-  * `VK_NV_cooperative_matrix`
-  * `VK_EXT_depth_clip_enable` (internal issue 1485).

-Change log for February 10, 2019 Vulkan 1.1.100 spec update:
-
-  * Update release number to 100.
-
-Public Issues:
-
-  * Clarify that scoped modification order only relates to
-    <<memory-model-atomic-operation, atomic writes>> (public pull request
-    906).
-  * Remove `readme.txt` reference from `xml/README.adoc` (public pull
-    request 907).
-  * Add missing slink:VkShaderResourceUsageAMD to the <<VK_AMD_shader_info>>
-    appendix (public pull request 908).
-  * Fix markup for <<VK_EXT_filter_cubic>> appendix (public pull request
-    911).
-  * Fix typo "`attachment`" (public pull request 914).
-  * Alias the enums for `VK_IMG_filter_cubic` properly to the corresponding
-    `VK_EXT_filter_cubic` enums, so they appear in the corresponding
-    enumerated types, instead of as #defines (Vulkan-Headers issue 40).
-
-Internal Issues:
-
-  * Remove nested conditionals in valid usage statements for
-    slink:VkFramebufferCreateInfo and flink:vkCmdPipelineBarrier by
-    duplicating statements along ifdef/ifndef paths for
-    VK_KHR_depth_stencil_resolve (internal issue 1527).
-  * Clarify allowed values of <<spirv-precision-operation, SPIR-V operations
-    near infinity>>. For very large results of operations the allowed range
-    of return values as defined in the spec didn't include the largest
-    finite number. In some rounding modes (eg. RTZ) the largest finite
-    number is the correctly rounded result, so it should be allowed.
-  * Require descriptor types to match in slink:VkCopyDescriptorSet.
-

-
-Change log for February 3, 2019 Vulkan 1.1.99 spec update:

-  * Minor update to `khronos.css` and markup fixes (originally proposed in
-    public pull request 901, but done via an internal MR).
-
-Internal Issues:
-
-  * Document restrictions on image queries for {YCbCr} formats in the
-    <<formats-requiring-sampler-ycbcr-conversion>> table as well as
-    for slink:sname:VkImageFormatProperties and slink:VkImageCreateInfo
-    (internal issue 1361).
-  * Correct type of the code:FragSizeEXT built-in in the
-    <<interfaces-builtin-variables, Built-In Variables>> section (internal
-    issue 1526).
-  * Clean up math in the <<textures, Image Operations>> chapter by
-    refactoring, using better naming conventions, updating diagrams to use
-    the correct orientation, etc. (internal merge request 2968).
-  * Fix minor typos for slink:VkImageCreateInfo and
-    slink:VkImageStencilUsageCreateInfoEXT.
-  * Add missing documentation for tlink:VkResolveModeFlagsKHR.
-  * Fix extension dependency of pname:scalarBlockLayout in the
-    <<features-features-requirements, Feature Requirements>> section.
-  * Fix indexing math for shader binding table calculations in the
-    <<shader-binding-table-indexing-rules, Indexing Rules>> section, and use
-    spelling "`any-hit`" consistently.
-  * Reconcile valid usage statement and text for sampled image layouts in
-    slink:VkWriteDescriptorSet
-    (https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/551).
-  * Make SPIR-V code:OpConvertUToPtr and code:OpConvertPtrToU operations
-    require a 64-bit integer for physical storage buffer pointers in the
-    <<spirvenv-module-validation, Validation Rules within a Module>>
-    section.

-Change log for January 13, 2019 Vulkan 1.1.98 spec update:
-
-  * Update release number to 98.
-
-Public Issues:
-
-  * Fix missing markup in flink:vkDestroyPipelineLayout valid usage
-    statement (pull request 882).
-  * Add missing contributors for `<<VK_EXT_buffer_device_address>>` (public
-    pull request 891).
-
-Internal Issues:
-
-  * Detect nested bullet points in valid usage blocks and warn about them
-    during VUID assignment (internal issue 1382).
-  * Update the style guide to document the process for reserving new bits in
-    bitmask types (internal issue 1411).
-  * Clarify for slink:VkApplicationInfo::pname:apiVersion and in the
-    <<fundamentals-validusage-versions, Valid Usage for Newer Core
-    Versions>> section when it is valid for an application to use a certain
-    version of Vulkan API functionality (for an instance and for a
-    device/physical device); and when the validation layers must generate an
-    error (internal issue 1412).
-  * Add optional <<memory-model-availability-visibility, transitive
-    availability/visibility operations to the memory model, including a new
-    pname:vulkanMemoryModelAvailabilityVisibilityChains feature for
-    slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR (internal issue
-    1460).
-  * Add the code:StorageBuffer storage class to those in the
-    <<interfaces-resources-descset, Descriptor Set Interface>> (internal
-    issue 1480).
-  * Add missing `returnedonly` tags for a number of returned extension
-    structures that can be passed in pname:pNext chains (internal issue
-    1515).
-  * Clean up and rearrange some spec language for
-    slink:VkRenderPassCreateInfo and slink:VkAttachmentReference.txt
-    (internal issue 1522).
-  * Correctly round the code:OpVectorTimesScalar and
-    code:OpMatrixTimesScalar SPIR-V operations in the <<Precision of core
-    SPIR-V Instructions>> table (internal merge request 2996).
-  * Work around cases in flink:vkCmdBeginTransformFeedbackEXT,
-    flink:vkCmdEndTransformFeedbackEXT, and
-    slink:VkPipelineCoverageModulationStateCreateInfoNV where an array
-    parameter is `optional` but the length is not in `vk.xml`. This is an
-    interim fix using `noautovalidity` + handcoded VU replacing those that
-    should be autogenerated (internal issue 2944 and
-    https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/480).
-  * Remove redundant capability validation of the code:float16 and code:int8
-    SPIR-V capabilities from the <<spirvenv-capabilities, Capabilities>>
-    section, since they are already covered in the preceding table.
-  * Update check_spec_links script, including validation for reference page
-    open blocks. Fix errors identified by the script.
-
------------------------------------------------------
-
-Change log for January 05, 2019 Vulkan 1.1.97 spec update:
-
-  * Update release number to 97.
-
-Public Issues:
-
-  * Add a special case to the <<renderpass-compatibility, Render Pass
-    Compatibility>> rules allowing single-subpass renderpasses to be
-    compatible even if they have different resolve attachment references
-    (public issue 835).
-  * Fix the miss shader binding table record address rule in the
-    <<shader-binding-table-indexing-rules, Miss Shaders>> section to index
-    by code:missIndex, not code:sbtOffset (public issue 875).
-
-Internal Issues:
-
-  * Add a missing anchor to the elink:VkSamplerCreateFlagBits language
-    (internal issue 1483).
-  * Add missing implicit valid usage include for slink:VkHdrMetadataEXT and
-    corresponding `noautovalidity` attributes in `vk.xml` for the
-    externally-defined metadata properties (internal issue 1514).
-  * Remove restrictions on the `mask` parameter of SPIR-V's
-    code:OpGroupNonUniformXor in the <<spirvenv-module-validation,
-    Validation Rules within a Module>> appendix (internal merge request
-    2971).
-  * Restore `noautovalidity` attribute for
-    slink:VkPipelineViewportWScalingStateCreateInfoNV::pname:pViewportWScalings
-    in `vk.xml` (internal merge request 2975).
-  * Update copyright dates on Khronos-copyrighted files to 2019 (internal
-    merge request 2980).

-Change log for December 16, 2018 Vulkan 1.1.96 spec update:
-
-  * Update release number to 96.
-
-Public Issues:
-
-  * Fix typo in `vk.xml` for `structextends` attribute of
-    slink:VkPhysicalDeviceShadingRateImagePropertiesNV (public PR 870).
-  * Fix links in optimized PDF output (public PR 879).
-
-Internal Issues:
-
-  * Add a link to GitHub contributors in the <<credits, Other Credits>>
-    section (internal issue 808).
-  * Clarify the behavior of command aliases described in the <<versions,
-    Core Revisions>> and <<initialization-functionpointers, Command Function
-    Pointers>> sections and the registry schema document with respect to
-    whether they are or are not the same entry point, and what the behaviour
-    of the ftext:vkGet*ProcAddr commands is for each alias (internal issue
-    1462).
-  * Update slink:VkPipelineShaderStageCreateInfo valid usage statements for
-    writing to code:Layer and code:viewportIndex to apply to any vertex
-    processing stage (internal issue 1475).
-  * Make sparse image creation optional for {YCbCr} formats in the
-    <<features-required-format-support, Required Format Support>> section
-    and the <<formats-requiring-sampler-ycbcr-conversion, Formats
-    requiring sampler {YCbCr} conversion for
-    ename:VK_IMAGE_ASPECT_COLOR_BIT image views>> table (internal issue
-    1476).
-  * Modify the valid usage statement for
-    flink:vkCmdDrawIndirectByteCountEXT::pname:vertexStride to use the
-    pname:maxTransformFeedbackBufferDataStride limit rather than the
-    pname:maxVertexInputBindingStride limit, which is a better match for
-    transform feedback related operations (internal issue 1487).
-  * Changed all members of slink:VkPhysicalDevicePCIBusInfoPropertiesEXT to
-    have the `uint32_t` type. This is an imcompatible change to an EXT
-    that's very recently released; although this is against usual Vulkan WG
-    policy, we discussed and consider this an acceptable risk, but have
-    polled the mesa-dev list in case there are use cases we missed (internal
-    issue 1492).
-  * Set spec vetsion to 1 for `VK_GOOGLE_hlsl_functionality1` and
-    `VK_GOOGLE_decorate_string` in `vk.xml` (internal MR 2948).
-  * Remove redundant valid usage statement `VkImageCreateInfo-pNext-02395`
-    (internal MR 2950).
-  * Add `check_spec_links.py` script, use it in Gitlab CI, and fix many
-    minor markup issues discovered by the script (internal MR 2955).
-  * Update `BUILD.md` to the current Ruby version (2.5.3), and make some
-    corresponding updates to per-platform build instructions (internal MR
-    2956).
-  * Fix binding numbers and other details in
-    flink:vkUpdateDescriptorSetWithTemplate.txt example code blocks
-    (internal MR 2960).
-  * Remove some nautovalidity="true" in `vk.xml` for NV extensions where
-    it's clearly wrong (internal MR 2970).

-    corresponding slink:slink:VkMemoryDedicatedRequirements and
-    slink:slink:VkMemoryDedicatedAllocateInfo structures in the description
-    of elink:VkExternalMemoryFeatureFlagBits (public issue 801).
-  * Fix miscellaneous minor markup and spelling issues in
-    `VK_NV_ray_tracing` extension (public pull request 860).
-  * Remove "returnedonly" from XML for
-    slink:VkPhysicalDeviceInlineUniformBlockFeaturesEXT and
-    slink:VkPhysicalDeviceVulkanMemoryModelFeaturesKHR (public issue 862).
-
-Internal Issues:
-
-  * Add to the description of the
-    <<features-limits-maxComputeSharedMemorySize,
-    pname:maxCompureSharedMemorySize>> feature to state the shared variables
-    should be packed at least as tightly as std430 (internal issue 1386).
-  * Fix and clarify various references to image and image view usage in
-    flink:vkCmdBindShadingRateImageNV, flink:vkCmdBeginRenderPass, and
-    slink:VkImageStencilUsageCreateInfoEXT (internal issue 1432).
-  * Require that the slink:VkImage mipmap chain match the Android hardware
-    buffer mipmap chain for slink:VkMemoryAllocateInfo (internal issue
-    1479).
-  * Fix the definition of slink:VkSwapchainCreateInfoKHR valid usage
-    statement 01778 (Vulkan-ValidationLayers!15)
-  * Fix descriptions of <<interfaces-builtin-variables-launchid,
-    code:LaunchIDNV>> and <<interfaces-builtin-variables-launchsize,
-    code:LaunchSizeNV>> to code:uvec3.

-
------------------------------------------------------
-
-Change log for November 25, 2018 Vulkan 1.1.94 spec update:
-
-  * Update release number to 94.
-
-Public Issues:
-
-  * Use the terms "`texel block`" and "`texel block size`" instead of "`data
-    element`" and "`element size`", and define "`element`" as an array slot.
-    In addition to the terminology changes, retitled the <<texel-block-size,
-    Representation and Texel Block Size>> section and added texel block size
-    / no. of texels/block information to the
-    <<features-formats-compatibility, Compatible Formats>> table. There is
-    some additional work underway to make sure the compatibility language
-    makes sense for all of uncompressed, compressed, and multiplanar formats
-    (public issue 763).
-  * Cleanup `VK_NV_ray_tracing` language (public issues 858, 859).
-
-Internal Issues:
-
-  * Specify in <<shaders-invocationgroups, Invocation and Derivative
-    Groups>> and <<textures-output-format-conversion, Texel Output Format
-    Conversion>> that derivative groups are quads when code:SubgroupSize >=
-    4 (internal issue 1390).
-  * Make the type of slink:VkDescriptorUpdateTemplateCreateInfo::pNext
-    `const` following pattern for the other stext:Vk*CreateInfo structures
-    (internal issue 1459).
-  * Specify that flink:vkCmdClearAttachments executes as a drawing command,
-    rather than a transfer command (internal issue 1463).
-  * Update `VK_NV_ray_tracing` to use code:InstanceId instead of
-    code:InstanceIndex.
-
-New Extensions:
-
-  * `VK_KHR_swapchain_mutable_format`
-  * `VK_EXT_fragment_density_map`

-    slink:VkAccelerationStructureTypeNV (public issue 848).
-  * Add missing suffix in description of slink:VkSubpassDescription2KHR
-    parameters (public pull request 851).
-  * Fix miscellaneous typos (public pull request 855).
-  * Add driver ID for Pastel (public pull request 856).
-  * Add missing include directive for slink:VkMemoryWin32HandlePropertiesKHR
-    implicit valid usage statements (public pull request 857).
-
-Internal Issues:
-
-  * Restrict the storage classes permitted for SPIR-V atomics to what is
-    actually supported, in the <<spirvenv-module-validation, Validation
-    Rules within a Module>> section (internal issue 1123).
-  * Add a missing Valid Usage statement to slink:VkRenderPassCreateInfo for
-    the case pname:stencilLoadOp == ename:VK_LOAD_OP_CLEAR, pname:layout ==
-    ename:VK_IMAGE_LAYOUT_DEPTH_STENCIL_READ_ONLY_OPTIMAL (internal issue
-    1408).
-  * Modify optimize-pdf script and Makefile to retain non-optimized original
-    PDF on errors (internal issue 1435).
-  * Add <<spirvenv-module-validation, SPIR-V validation rules>> stating that
-    only the listed code:BuiltIn decorations are permitted, and only when
-    relevante features and extensions are enabled (internal issue 1449).
-  * Remove some duplicated Valid Usage IDs created via cut & paste error
-    (internal issue 1455).
-  * Build HTML output for extension reference pages (internal issue 1461).
-  ** Improve genRef.py handling of aliases defined inside other refpages.
-  ** Emit aliases in pygenerator.py.
-  ** Add XML noautovalidity flag for VkRenderPassCreateFlags until there
-     are some corresponding FlagBits defined.
-  ** Corrected types= attribute on some refpage blocks to 'flags'

-    slink:VkSubpassDependency2KHR, flink:vkCmdBeginRenderPass,
-    flink:vkCmdBeginRenderPass2KHR, and slink:VkRenderPassBeginInfo
-    discovered while adding `VK_KHR_create_renderpass2` to the validation
-    layers.

-
-Change log for November 12, 2018 Vulkan 1.1.92 spec update:
-
-  * Update release number to 92.
-
-Public Issues:
-
-  * Move and modify valid usage statements dealing with pname:aspectMask in
-    flink:vkCmdClearColorImage, flink:vkCmdClearDepthStencilImage, and
-    slink:VkClearAttachment, so they are in places where all necessary
-    information is available (public issue 529).
-  * Fix math markup in <<textures-texel-anisotropic-filtering, Texel
-    Anisotropic Filtering>> (public pull request 840).
-  * Fix misspellings (public pull request 845).

-
-  * Add installation instructions and a Makefile "`chunked`" target for
-    chunked HTML generation (internal issue 1352).
-  * Fix pipeline mesh diagram style; also fix a minor bug in the classic
-    pipeline diagram where vertex/index buffers wrongly fed into the vertex
-    shader (internal issue 1436).
-  * Make asciidoctor ERROR output raise an error, and don't suppress
-    executed command output from CI make invocation (internal issue 1454).
-  * Minor typo fixes and clarifications for `VK_NV_raytracing`.
-  * Cleanup extension-specific properties
-  ** Remove duplicated documentation for pname:maxDiscardRectangles,
-     pname:pointClippingBehavior, and pname:maxVertexAttribDivisor (they
-     shouldn't be documented with the other members of
-     slink:VkPhysicalDeviceLimits at all).
-  ** Remove duplicate anchor for pname:maxVertexAttribDivisor
-  ** Consistently document stext:VkPhysicalDevice<Extension>PropertiesKHR
-  *** Always document pname:sType/pname:pNext (was inconsistent before)
-  *** Always mention chaining to slink:VkPhysicalDeviceProperties2 (and not
-      as slink:VkPhysicalDeviceProperties2KHR)
-  *** Always include Valid Usage statements last
-  * Update Makefile 'checklinks' target and associated scripts, and fix
-    markup problems identified by checkLinks.py, so that we can rely on the
-    checklinks script as part of Gitlab CI.
-
------------------------------------------------------
-
-Change log for November 4, 2018 Vulkan 1.1.91 spec update:
-
-  * Update release number to 91.
-
-Public Issues:
-
-  * Update Ubuntu subsystem build instructions in `BUILD.adoc` (public pull
-    request 624).
-  * Delete the `VK_KHR_mir_surface` extension from the Specification and
-    XML, due to EOL of the only driver known to have supported it, and
-    near-EOL of Mir itself (public issue 814).
-  * Fix options for some figures that were using old ones (public pull
-    request 841).
-  * Fix various accidentally repeated words (public pull request 843).
-  * Use `time.process_time()`, introduced in Python 3.3, in the scripts
-    instead of `time.clock()`, which will be removed in Python 3.8 (public
-    pull request 844).
-
-Internal Issues:
-
-  * Update valid usage statements for
-    `VK_ANDROID_external_memory_android_hardware_buffer` in
-    slink:VkMemoryAllocateInfo,
-    slink:VkImportAndroidHardwareBufferInfoANDROID, and
-    flink:vkGetAndroidHardwareBufferPropertiesANDROID to actually be
-    verifiable (internal issue 1419).
-  * Update valid usage statements for
-    `VK_ANDROID_external_memory_android_hardware_buffer` in
-    slink:VkMemoryAllocateInfo, slink:VkImageCreateInfo, and
-    slink:VkImageViewCreateInfo to move valid usage statements in
-    doubly-nested bullet points up one level, accomodating limitations of
-    the valid usage extraction script that creates `validusage.json`
-    (internal issue 1434).
-  * Fix typo etext:VK_ACCESS_SHADING_RATE_IMAGE_BIT_NV to the correct
-    ename:VK_ACCESS_SHADING_RATE_IMAGE_READ_BIT_NV.
-  * Add missing etext:VK_STRUCTURE_TYPE_* tokens to appendices for
-    extensions missing them.
-
-New Extensions:

-
-Change log for October 28, 2018 Vulkan 1.1.90 spec update:
-
-  * Update release number to 90.
-
-Public Issues:
-
-  * Tag flink:vkQueueWaitIdle as `externsync` in `vk.xml` (public pull
-    request 815).
-  * Update README (public pull request 834).
-  * `VK_NV_framebuffer_mixed_samples` and `VK_AMD_mixed_attachment_samples`
-    had confusing and contradictory valid usage statements when read in the
-    all-extensions spec build. Change them to explicitly mention which
-    extension each is for (public issue Vulkan-ValidationLayers/issues/353).
-
-Internal Issues:
-
-  * Update `COPYING.md` to clarify how externally generated Vulkan
-    Specifications (for translations, annotations, or other reasons) must be
-    copyrighted, and acknowledge the Exception Clause on the `vk.xml`
-    license (internal issue 1079).
-  * Specify that flink:vkGetPhysicalDeviceImageFormatProperties may: return
-    pname:maxMipLevels 1 if the format is ycbcr (internal issue 1361).
-  * Clarify previously underspecified language for
-    flink:vkCmdPushConstants::pname:pStageFlags regarding use of push
-    constants across multiple pipelines (internal issue 1403).
-  * Fix typo in XML/headers for
-    ename:VK_STRUCTURE_TYPE_IMAGE_DRM_FORMAT_MODIFIER_EXPLICIT_CREATE_INFO_EXT,
-    which was previously
-    etext:VK_STRUCTURE_TYPE_IMAGE_EXCPLICIT_DRM_FORMAT_MODIFIER_CREATE_INFO_EXT
-    (internal issue 1428).
-  * Fix markup of equations that were sporadically breaking the
-    `optimize-pdf` step of PDF generation, due (apparently) to inconsistent
-    treatment of unwrapped multicharacter terms by different LaTeX parsers
-    (internal issue 1435).
-  * For the <<memory-model-synchronizes-with synchronizes-with>> memory
-    model relation cases involving a release barrier plus relaxed atomic
-    write, treat the atomic as if it were a release atomic and allow the
-    acquire side to read from its hypothetical release sequence. This is
-    more consistent with how C++ defines synchronization for release fences
-    (internal issue cross-api/memory-model#72).
-  * Minor editorial changes to the <<memory-model, memory model>> appendix
-    based on external feedback.
-
------------------------------------------------------
-
-Change log for October 21, 2018 Vulkan 1.1.89 spec update:
-

-    Relationship>> table with missing types (public pull request 820).
-  * Miscellaneous minor markup cleanup (public pull request 822).
-  * Fix copy/paste bugs in the description of how implicit
-    availability/visibility operations for atomics/barriers are ordered in
-    the <<memory-model-availability-visibility-semantics, Availability and
-    Visibility Semantics>> section (public issue 823).
-  * Add ename:VK_PIPELINE_STAGE_SHADING_RATE_IMAGE_BIT_NV bit missing from
-    the mesh shading list of the <<synchronization-pipeline-graphics,
-    graphics pipeline>> (public issue 824).
-
-Internal Issues:
-
-  * Clarify that only statically used members of a push constant block need
-    to be in the push constant range, and stop referring to block members as
-    "`variables`" in the <<interfaces-resources-pushconst, Push Constant
-    Interface>> section. This is related to
-    https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/340
-    (internal issue 1401).
-  * Clarify interaction between flink:vkCmdSetDeviceMask and render pass
-    control commands in the slink:VkDeviceGroupRenderPassBeginInfo section
-    (internal issue 1416).
-  * Miscellaneous minor markup cleanup.
-  * Remove types defined by `"disabled"` extensions from
-    validextensionstructs in the XML processing scripts, so downstream code
-    generators don't emit them.
-

-
-  * Update release number to 88.
-
-Public Issues:
-
-  * Make clear that

-    bitmask, and correct a typo in the spelling of
-    slink:VkDebugUtilsMessengerCreateInfoEXT.txt::pname:messageType (public
-    pull request 800).
-  * Make an ABI-compatible change of the type of
-    slink:VkPhysicalDeviceDriverPropertiesKHR::pname:driverID to use the new
-    elink:VkDriverIdKHR type (public issue 811).
-
-Internal Issues:
-
-  * Clarify for the <<features-features-shaderStorageImageExtendedFormats>>
-    feature and in the <<spirvenv-capabilities-table>> that the feature
-    means that all of the formats are supported, and that otherwise the
-    features can be queried per-format (internal issue 1273).
-  * Clarified interactions of `VK_EXT_external_memory_host` with host cache
-    management commands and structures flink:vkMapMemory,
-    flink:vkFlushMappedMemoryRanges, slink:VkMappedMemoryRange, and
-    flink:vkUnmapMemory using the new glossary term "`Host Mapped Device
-    Memory`" (internal issue 1385).
-  * Update the language for flink:vkCreateViSurfaceNN.txt describing the
-    pname:currentExtent of a VI surface to more accurately reflect current
-    capabilities, replacing "`undefined`" with more explicit behavior
-    (internal issue 1410).
-
-New Extensions:
-
-  * `VK_EXT_calibrated_timestamps`
-  * `VK_EXT_image_drm_format_modifier` (this extension was previously
-    disabled in vk.xml, and has now been enabled after some changes to fix
-    performance issues).
-  * `VK_EXT_pci_bus_info`
-  * `VK_EXT_transform_feedback`
-  * `VK_GOOGLE_hlsl_functionality1`, exposing support for
-    `SPV_GOOGLE_hlsl_functionality1`.

-    to the same subpass dependency (public pull request 756).
-  * Describe default value of `"optional"` attribute in the registry schema
-    document (public issue 769)
-  * Fix links in <<VK_NVX_raytracing>> extension (public pull request 805).
-  * Mark the <<VK_KHR_mir_surface>> extension obsolete (see public issue 814
-    - does not close this, however).
-  * Fix missing endif in Image Creation block (public issue 817).
-
-Internal Issues:
-
-  * Clarify that the compressed texture formats corresponding to
-    <<features-features-textureCompressionETC2>>,
-    <<features-features-textureCompressionASTC_LDR>>, and
-    <<features-features-textureCompressionBC>> is not contingent on the
-    feature bits, and may be supported even if the features are not enabled
-    (internal issue 663).
-  * Clarify that code:FragStencilRefEXT is output only in the
-    <<interfaces-builtin-variables, Built-In Variables>> section (internal
-    issue 1173).
-  * Identify and correct many overly-aggressive uses of "`undefined`", and
-    narrow them down, where straightforward to do so. Mark such resolved
-    uses of "`undefined`" with the custom undefined: macro. Add a new
-    <<writing-undefined, Describing Undefined Behavior>> section (internal
-    issue 1267).
-  * Don't require code:inline_uniform_block descriptors to be populated
-    before use in the flink:vkAllocateDescriptorSets section (internal issue

-    conformance tests.
-  * Fix vendor tag in reserved extension 237 constants. Does not affect
-    anything since it's just a placeholder, but this should avoid further
-    comments.

-    buffer/image memory requirements (public issue 661).
-  * Correct scope (conditional constructs) in valid usage statement for
-    slink:VkBindImageMemoryInfo (public pull request 684).
-  * Clean up minor markup issues and typos in the
-    `VK_ANDROID_external_memory_android_hardware_buffer` extension appendix
-    (public pull request 698).
-  * Modify registry processing script to avoid irrelevant warnings of benign
-    enumerant redefinitions (public pull request 705).
-  * Fix some duplicate words and some misspelled "`stagess`" (public pull
-    request 712)
-
-Internal Issues:
-
-  * Enable continuous integration tests on the internal Khronos gitlab
-    server by adding a .gitlab-ci.yml file. Note: this does not implement CI
-    on the public Github repository (internal issue 408).
-  * Add link from description of depth clamping in the <<fragops-depth,
-    depth test>> section to the
-    slink:VkPipelineRasterizationStateCreateInfo::pname:depthClampEnable
-    parameter which enables it, making it easily searchable / findable
-    (internal issue 1125).
-  * Clarify that arrays of arrays of descriptors are not allowed in the
-    <<interfaces-resources-descset, Descriptor Set Interface>> and
-    <<interfaces-resources-setandbinding, DescriptorSet and Binding
-    Assignment>> sections (internal issue 1192).
-  * Comment out some redundant nested asciidoctor conditionals in the
-    slink:VkImageViewCreateInfo valid usage block, and explain in all cases
-    why the redundant conditional exist and are commented out (internal
-    issue 1231).
-  * Move a valid usage statement from slink:VkCommandPoolCreateInfo to the
-    parent flink:vkCreateCommandPool, where the device queue is known
-    (internal issue 1233).
-  * Add new slink:VkBaseInStructure and slink:VkBaseOutStructure types which
-    can be used by extensions and implementations for handling Vulkan
-    sType/pNext style structures in a more generic way (internal issue
-    1265).
-  * Clarify that
-    slink:VkAndroidHardwareBufferFormatPropertiesANDROID::pname:formatFeatures
-    only applies to external-format images. Add references to this in valid
-    usage statements that previously only referred to
-    slink:VkFormatProperties (internal issue 1244).
-  * Fix the description of elink:VkPipelineCreateFlagBits enumerant
-    ename:VK_PIPELINE_CREATE_VIEW_INDEX_FROM_DEVICE_INDEX_BIT to match the
-    name (internal issue 1279).
-  * Add a NOTE to the <<interfaces-resources-setandbinding, DescriptorSet
-    and Binding Assignment>> section making it clear that variables sharing
-    a storage class may use identical descriptor set and bindings.
-    Specifically state the sometimes misunderstood ability to have one or
-    more differently typed image descriptors sharing a descriptor set and
-    binding (internal SPIR-V issue 264).
-  * Make DynamicIndexing features and capabilities also control the
-    uniformity of the descriptor used in memory access instructions in the
-    <<interfaces-resources-descset, Descriptor Set Interface>> section. This
-    makes them also apply to variable_pointer usage, which can bypass the
-    array indexing operation (internal SPIR-V issue 289).
-
-Other Issues:
-
-  * Correct flink:vkCmdBlitImage limitations on cubic blits to be 2D only,
-    not 3D.
-  * Update valid usage statements for slink:VkRenderPassCreateInfo and
-    slink:VkInputAttachmentAspectReference.
-  * Move YCbCr-related VU statements from slink:VkDescriptorImageInfo to
-    slink:VkWriteDescriptorSet, where all needed information is known, and
-    remove redundant statements.
-  * Move SPIR-V restriction that images be of either sampled or storage
-    types from the <<interfaces-resources-descset, Descriptor Set
-    Interface>> section to the <<spirvenv-module-validation, Validation
-    Rules within a Module>> section of the SPIR-V appendix.

-  * Re-remove several valid usage statements from slink:VkImageCreateInfo
-    that had previously been removed at the time that
-    ename:VK_IMAGE_CREATE_EXTENDED_USAGE_BIT was introduced. These
-    statements had incorrectly been restored due to an glitch while merging
-    from the old `1.0` branch to the current `master` branch (public issue
-    683).
-
-Internal Issues:
-
-  * Fix reference page generation and configure build to generate reference
-    pages 1.1 with all extensions, rather than core only, as was the case
-    for the 1.0 ref pages (internal issues 484, 1056, 1205).
-  * Require that
-    slink:VkMemoryDedicatedRequirements::pname:prefersDedicateAllocation is
-    ename:VK_TRUE when
-    slink:VkMemoryDedicatedRequirements::pname:requiresDedicateAllocation is
-    ename:VK_TRUE (internal issue 1222).
-  * Fix Ruby extension code so `diff_html` Makefile target works (internal
-    issue 1230).
-  * Update `genRelease` script to generate 1.1 + all extensions reference
-    pages - but not the single-page HTML / PDF versions, which are even
-    larger than the API spec (internal issue 1245).
-
-Other Issues:
-
-  * Add missing attributes to `vk.xml` for `VK_ANDROID_native_buffer`.
-  * Specify that the slink:VkAttachmentDescription::pname:format member is
-    the format of the image *view* that will be used for the attachment.
-  * Use core sname:VkPhysicalDeviceFeatures2 in the `structextends` `vk.xml`
-    attribute for sname:VkPhysicalDeviceDescriptorIndexingFeaturesEXT and
-    sname:VkPhysicalDeviceDescriptorIndexingPropertiesEXT, rather than the
-    KHR equivalent it was promoted from.
-  * Fix the "`Fragment Input Attachment Interface`" glossary entry to match
-    the specification body.
-  * Clarify the interaction of sRGB images used as storage or texel buffers
-    with <<textures-output-format-conversion, Texel Output Format
-    Conversion>>.
-  * Moved three valid usage statements from
-    slink:VkRenderPassMultiviewCreateInfo up to
-    slink:VkRenderPassCreateInfo, and added a new valid usage statement for
-    slink:VkRenderPassInputAttachmentAspectCreateInfo.
-  * Added valid usage statements for slink:VkBufferMemoryBarrier and
-    slink:VkImageMemoryBarrier reflecting the global requirement that
-    "`non-sparse resources must be bound to memory before being recorded to
-    command`".
-

-
-Change log for April 5, 2018 Vulkan 1.1.72 spec update:
-
-  * Update release number to 72.
-
-Github Issues:
-
-  * Restructure the repository to put the specification `Makefile` and
-    associated spec source material at the top level, `vk.xml` and
-    associated scripts material in `xml/`, and generated include and source
-    files in `include/vulkan/` and `src/ext_loader/`, respectively (public
-    issue 436).
-  * Add missing bullet point markup to flink:vkCmdCopyImage valid usage
-    statement, so it gets a VUID assigned (public issue 627).
-  * Fix broken links in a couple of extension appendices (public pull
-    request 665).
-  * Add the <platform> tag to the index in section 4.1 of the registry
-    schema documentation, and add the protect= attribute of <extension>
-    tags to the comments in `registry.rnc` (public issues 673, 678).
-  * Add missing valid usage statements for sparse image interactions to
-    flink:VkImageCreateInfo (public pull request 675).
-  * Fix improper usage and grammar of "`can: not`" (public pull request
-    681).
-  * Remove duplicate spec language and NOTE on present layout between the
-    flink:vkAcquireNextImageKHR and flink:vkAcquireNextImage2KHR commands
-    (public pull request 685).
-  * Fix some typos and markup issues (public pull request 689; public issues
-    642, 667, 687).
-  * Fix typo etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT ->
-    ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT in the
-    <<external-semaphore-handle-types-compatibility, External semaphore
-    handle types compatibility>> table (public pull request 691).
-
-Internal Issues:
-
-  * Remove the need for the "`noautovalidity`" attribute on extension
-    structures in `vk.xml`. It is now implied by the "`structextends`"
-    attribute instead (internal issue 942).
-  * Replace uses of "`currently bound`" with "`bound`", since "`currently`"
-    is redundant and distracting, and add a corresponding rule to the style
-    guide (internal issue 993).
-  * Fixed subtle issues with the last updates to flink:vkAcquireNextImageKHR
-    language that had resulted in ambiguities (internal issue 1178).
-  * Make it clear that only one query of a given type is allowed at a time
-    by reordering valid usage statements for flink:vkCmdBeginQuery and
-    flink:vkCmdEndQuery, and removing redundant ones (internal issue 1213).
-  * Swapped OL1 and OL3 in `tessparamUL.svg` to match previous version, and
-    fixed where "`(no edge)`" appears (internal issue 1215).
-
-Other Issues:
-
-  * Fixed a minor problem with the valid usage statement extraction script,
-    and corresponding markup in the spec source.
-
-New Extensions:
-
-  * `VK_AMD_shader_core_properties`
-  * `VK_EXT_descriptor_indexing`
-  * `VK_NV_shader_subgroup_partitioned`
-
------------------------------------------------------
-
-Change log for March 16, 2018 Vulkan 1.1.71 spec update:
-
-  * First public update for Vulkan 1.1.
-
-Github Issues:
-
-  * Refer to standard sparse image block shape format tables explicitly in
-    the <<sparsememory-standard-shapes, Standard Sparse Image Block Shapes>>
-    section (public issue 93).
-  * Add the missing definition of the code:LocalInvocationIndex decoration
-    in the <<interfaces-builtin-variables, Built-In Variables>> section
-    (public issue 532).
-  * Clarify dynamic state definition in the introduction to the <<pipelines,
-    Pipelines>> section and the new <<pipelines-dynamic-state, Dynamic
-    State>> subsection (public issue 620).
-  * Clarified deprecation statement in the `VK_AMD_negative_viewport_height`
-    appendix (public issue 674).
-  * Fix parameter descriptions for flink:vkCreateIndirectCommandsLayoutNVX
-    (public issue 677).
-
-Internal Issues:
-
-  * Remove description of <<primsrast-points, rasterization point size>>
-    being taken from the tessellation control shader, since there are no
-    circumstances under which you can have TCS without TES (internal issue
-    522).
-  * Define <<copies-images-format-size-compatibility, _size-compatible_
-    image formats>> for flink:vkCmdCopyImage, add it to the glossary, and
-    use that definition for slink:VkImageViewCreateInfo (internal issue
-    771).
-  * Change brief descriptions of enumerant names, and of parameters which
-    are enumerants, from "`enum *indicates*`" to "`enum *specifies*`" for
-    consistency, and add a markup style guide rule (internal issue 862).
-  * Clarify how execution dependencies interact with
-    <<synchronization-submission-order, submission order>> at numerous
-    places in the <<renderpass, Render Pass>> and <<synchronization,
-    Synchronization>> chapters (internal issue 1062).
-  * Clarify statement in the <<interfaces-resources-setandbinding,
-    DescriptorSet and Binding Assignment>> section that only interface
-    variables statically used by the entry point used in a pipeline must be
-    present in the descriptor set layout (internal issue 1172).
-  * Flip sparse image diagrams with partially full mip levels vertically, to
-    match graph origins of other image diagrams (internal issue 1176).
-  * Update new SVG diagrams to have consistent style and base font size,
-    increase consistency of primitive topology diagrams, and add a section
-    to the style guide on creating and editing images in a consistent style
-    (internal issue 1177).
-  * Resolve problems with valid usage statement extraction by fixing
-    existing VUID tags for interfaces promoted to version 1.1 and fixing
-    conditional directives around
-    VUID-VkMemoryDedicatedAllocateInfo-image-01797 (internal issue 1184).
-  * Strip `KHR` suffixes from a few interfaces promoted to Vulkan 1.1 that
-    were missed previously (internal issue 1185).
-  * Restrict code:OpImageQuerySizeLod and code:OpImageQueryLevels to only
-    work on code:Image operands with their code:Sampled operand set to 1. In
-    other words, these operations are not defined to work with storage
-    images (internal issue 1193).
-  * Recycle extension slot for extension #82 in `vk.xml`. This extension was
-    never published (internal issue 1195).
-  * Add an issue to the `VK_KHR_maintenance1` appendix noting that zero
-    height viewports are allowed when this extension is enabled (internal
-    issue 1202).
-  * Fix slink:VkDescriptorSetLayoutBinding description so that shader stages
-    always use descriptor bindings, not the other way around (internal issue
-    1206).
-  * Fix field name for
-    slink:VkInputAttachmentAspectReference::pname:inputAttachmentIndex
-    (internal issue 1210).
-
-Other Issues:
-
-  * Fix a few broken links in the <<versions-1.1, Version 1.1>> appendix.
-  * Replace a few old refBegin/refEnd tags with open block markup around
-    interfaces, and remove old KHX VUID tags that were breaking the valid
-    usage statement extraction.
-  * Fix error codes accidentally tagged as success codes in `vk.xml` for
-    flink:vkGetSwapchainCounterEXT.
-  * Added valid usage statements for ftext:vkBind*Memory2 input structures
-    stext:VkBind*MemoryInfo, and fix a pname:image -> pname:buffer typo in a
-    couple of places.
-  * Fix swapped descriptions of elink:VkDescriptorType enums
-    ename:VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE and
-    ename:VK_DESCRIPTOR_TYPE_STORAGE_IMAGE (reported via tweet).
-
-New Extensions:
-
-  * `VK_ANDROID_external_memory_android_hardware_buffer`
-
------------------------------------------------------
-
-Change log for March 7, 2018 Vulkan 1.1.70 spec update:
-
-  * Vulkan 1.1 initial release. Bump API patch number and header version
-    number to 70 for this update. The patch number will be used for both
-    Vulkan 1.1 and Vulkan 1.0 updates, and continues to increment
-    continuously from the previous Vulkan 1.0.69 update.
-
-    NOTE: We are not publishing an updated 1.0.70 specification, or 1.1
-    reference pages, along with 1.1.70. There are still minor issues to work
-    out with those build targets. However, we will soon generate all three
-    types of documents as part of the regular spec update cycle.
-
-    NOTE: The GitHub KhronosGroup/Vulkan-Docs repository now maintains the
-    current specification in the `master` branch. The `1.0` branch is out of
-    date and will not be maintained, since we will be generating both 1.1
-    and 1.0 specifications from the `master` branch in the future.
-
-Github Issues:
-
-  * Clarify how mapped memory ranges are flushed in
-    flink:vkFlushMappedMemoryRanges (public issue 127).
-  * Specify that <<synchronization-pipeline-stages, Pipeline Stages>> are a
-    list of tasks that each command performs, rather than necessarily being
-    discrete pieces of hardware that one task flows through. Add a
-    "`synchronization command`" pipeline type which all synchronization
-    command execute (it's just TOP + BOTTOM), with an explanatory note
-    (public issue 554).
-
-Internal Issues:
-
-  * Regenerate all images used in the spec in Inkscape with a consistent
-    look-and-feel, and adjust image size attributes so they're all legible,
-    and not too large with respect to the spec body text (internal issue
-    701).
-  * Document in the <<extensions,extensions>> appendix and in the style
-    guide that `KHX` extensions are no longer supported or used in the
-    Vulkan 1.1 timeframe (internal issue 714).
-  * Remove the leftover equations_temp directory after PDF build completes
-    (internal issue 925).
-  * Update the <<credits, Credits (Informative)>> appendix to include
-    contributors to Vulkan 1.1, and to list them according to the API
-    version(s) they contributed to (internal issue 987).
-  * Add a NOTE to the introduction explaining that interfaces defined by
-    extensions which were promoted to Vulkan 1.1 are now expressed as
-    aliases of the Vulkan 1.1 type (internal issue 991).
-  * Instrument spec source conditionals so spec can be built with 1.1
-    features, extensions promoted to 1.1, or both (internal issues 992,
-    998).
-  * Modify the XML schema and tools to support explicit aliasing of types,
-    structures, and commands, and use this to express the promotion of 1.0
-    extensions to 1.1 core features, by making the extension interfaces
-    aliases of the core features they were promoted to. Mark up promoted
-    interfaces to allow still generating 1.0 + extension specifications
-    (internal issue 991).
-  * Platform names, along with corresponding preprocessor symbols to enable
-    extensions specific to those platforms, are now reserved in vk.xml using
-    the <platform> tag. Update the registry schema and schema specification
-    to match (internal issue 1011).
-  * Updated the <<textures-texel-replacement, Texel Replacement>> section to
-    clarify that reads from invalid texels for image resources result in
-    undefined values (internal issue 1014).
-  * Modify description of patch version so it continues to increment across
-    minor version changes (internal issue 1033).
-  * Clarify and unify language describing physical device-level core and
-    extension functionality in the <<fundamentals-validusage-extensions,
-    Valid Usage for Extensions>>, <<fundamentals-validusage-versions, Valid
-    Usage for Newer Core Versions>>, <<initialization-functionpointers
-    Command Function Pointers>>, <<initialization-phys-dev-extensions,
-    Extending Physical Device From Device Extensions>>
-    <<extended-functionality-instance-extensions-and-devices, Instance
-    Extensions and Device Extensions>> sections and for
-    flink:vkGetPhysicalDeviceImageFormatProperties2. This documents that
-    instance-level functionality is tied to the loader, and independent of
-    the ICD; physical device-level functionality is tied to the ICD, and
-    associated with device extensions; physical devices are treated more
-    uniformly between core and extensions; and instance and physical
-    versions can be different (internal issue 1048).
-  * Updated the <<commandbuffers-lifecycle, Command Buffer Lifecycle>>
-    section to clarify the ability for pending command buffers to transition
-    to the invalid state after submission, and add a command buffer
-    lifecycle diagram (internal issue 1050).
-  * Clarify that some flink:VkDescriptorUpdateTemplateCreateInfo parameters
-    are ignored when push descriptors are not supported (internal issue
-    1054).
-  * Specify that flink:vkCreateImage will return an error if the image is
-    too large, in a NOTE in the slink:VkImageFormatProperties description
-    (internal issue 1078).
-  * Remove near-duplicate NOTEs about when to query function pointers
-    dynamically in the <<initialization, Initialization>> chapter and
-    replace by extending the NOTE in the <<fundamentals-abi, Application
-    Binary Interface>> section (internal issue 1085).
-  * Restore missing references to "`Sparse Resource Features`" in the
-    flink:VkBufferCreateFlagBits description (internal issue 1086).
-  * Tidy up definitions of descriptor types in the `GL_KHR_vulkan_glsl`
-    specification, the <<descriptorsets, Resource Descriptors>> section and
-    its subsections, and the <<interfaces-resources-descset, Descriptor Set
-    Interface>> for consistency, reduction of duplicate information, and
-    removal of GLSL correspondance/examples (internal issue 1090).
-  * Correctly describe code:PrimitiveId as an Input for tessellation control
-    and evaluation shaders, not an Output (internal issue 1109).
-  * Relax the requirements on chroma offsets for nearest filtering in
-    <<textures-implict-reconstruction, Implicit Reconstruction>> (internal
-    issue 1116).
-
-Other Issues:
-
-  * Clarify the intended relationship between specification language and
-    certain terms defined in the Khronos Intellectual Property Rights
-    policy. Specific changes include:
-  ** Rewrote IP/Copyright preamble and introduction to better agree with
-     normative language both as laid out in the introduction, and the
-     Khronos IPR policy.
-  ** Added notion of fully informative sections, which are now tagged with
-     "`(Informative)`" in their titles.
-  ** Removed non-normative uses of the phrase "`not required`"
-  ** Clarified the distinction between terms "`optional`" and "`not
-     required:`" as they relate to the IPR Policy, and updated specification
-     text to use terms consistent with the intent.
-  ** Reduced additions to RFC 2119, and ensured the specification agreed
-     with the leaner language.
-  ** Removed the terms "`hardware`", "`software`", "`CPU`", and "`GPU`" from
-     normative text.
-  ** Moved several paragraphs that should not have been normative to
-     informative notes.
-  ** Clarified a number of definitions in the Glossary.
-  ** Updated the document writing guide to match new terminology changes.
-  * Explicitly state in the <<fundamentals-objectmodel-lifetime-acquire,
-    application memory lifetime>> language that for objects other than
-    descriptor sets, a slink:VkDescriptorSetLayout object used in the
-    creation of another object (such as slink:VkPipelineLayout or
-    slink:VkDescriptorUpdateTemplateKHR) is only in use during the creation
-    of that object and can be safely destroyed afterwards.
-  * Updated the <<textures-scale-factor, Scale Factor Operation>> section to
-    use the ratio of anisotropy, rather than the integer sample rate, to
-    perform the LOD calculation. The spec still allows use of the sample
-    rate as the value used to calculate the LOD, but no longer requires it.
-  * Update `vulkan_ext.c` to include all platform-related definitions from
-    the Vulkan platform headers, following the split of the headers into
-    platform-specific and non-platform-specific files.
-  * Fix bogus anchor name in the <<commandbuffers, Command Buffers>> chapter
-    which accidentally duplicated an anchor in the pipelines chapter. There
-    were no reference to this anchor, fortunately.
-  * Add valid usage statement for slink:VkWriteDescriptorSet and
-    slink:VkCopyDescriptorSet requiring that the slink:VkDescriptorSetLayout
-    used to allocate the source and destination sets must not have been
-    destroyed at the time flink:vkUpdateDescriptorSets is called.
-  * Document mapping of subgroup barrier functions to SPIR-V, and clarify a
-    place where subgroupBarrier sounds like it's execution-only in the
-    standalone `GL_KHR_shader_subgroup` specification.
-  * Use an HTML stylesheet derived from the Asciidoctor `colony` theme, with
-    the default Arial font family replaced by the sans-serif Noto font
-    family.
-  * Numerous minor updates to README.adoc, build scripts, Makefiles, and
-    registry and style guide specifications to support Vulkan 1.1 outputs,
-    use them as defaults, and remove mention of `KHX` extensions, which are
-    no longer supported.
-
-
-New Extensions:
-
-  * `VK_EXT_vertex_attrib_divisor`

------------------------------------------------------
-
-Change log for February 19, 2018 Vulkan 1.0.69 spec update:
-
-  * Bump API patch number and header version number to 69 for this update.
-
-Github Issues:
-
-  * Clean up description of synchronization for flink:vkAcquireNextImageKHR
-    (public issue 626).
-  * Move valid usage statements requiring offset and extent to respect image
-    transfer granularity requirements of the queue family they are submitted
-    against from slink:VkImageCopy and slink:VkBufferImageCopy to the
-    corresponding flink:vkCmdCopyImage, flink:vkCmdCopyBufferToImage, and
-    flink:vkCmdCopyImageToBuffer commands, where are relevant information is
-    known (public issue 654).
-  * Clarify that flink:vkGetDeviceProcAddr only supports device-level
-    commands (public issue 655).
-
-Internal Issues:
-
-  * Associate each elink:VkDescriptorType with a type of descriptor, and
-    link to descriptions of those types (internal issue 860).
-  * Rework valid usage extraction script to better utilize and respond to
-    spec markup, and fix some spec markup accordingly (internal issues 846,
-    909, 945).
-  * Rephrase flink:vkCmdPushConstants valid usage to allow overlapping push
-    constant ranges in different shader stages (internal issue 1103).
-  * Fix problem with diff_html target in extension.rb (internal issue 1104).
-  * Modify valid usage statements for slink:VkClearDepthStencilValue,
-    slink:VkGraphicsPipelineCreateInfo, slink:VkViewport, and
-    flink:vkCmdSetDepthBounds, and the description of vkCmdSetDepthBias, to
-    clarify that clamping is applied if and only if the
-    `VK_EXT_depth_range_unrestricted` is not enabled (internal issue 1124),
-    in versions of the specification built with that extension included.
-  * Resolve contradictions and use of undefined "`per-sample shading`" term
-    in the <<primsrast-sampleshading, Sample Shading>> and
-    <<shaders-fragment-execution, Fragment Shader Execution>> sections; for
-    the <<features-features-sampleRateShading, sampleRateShading feature>>;
-    for code:FragCoord, code:SampleId, and code:SamplePosition; and for
-    slink:sname:VkPipelineMultisampleStateCreateInfo (internal issue 1134).
-  * Clarify the meaning of the ptext:maxDescriptorSet* limits in footnote 8
-    of the <<features-limits-required,Required Limits>> table (internal
-    issue 1139).
-  * Fix broken NOTE markup in slink:VkSamplerCreateInfo.txt (internal issue
-    1140).
-  * Remove extend comparison language from valid usage statement for
-    slink:VkImageCreateInfo, turning it into a simple validation of
-    pname:mipLevels against pname:maxMipLevels (internal issue 1151).
-  * Update valid usage statements for slink:VkImageCopy when the
-    `VK_KHR_maintenance1` extension is enabled to allow multi-slice 2D <->
-    3D copies when the pnaem:extent.depth parameter specifies the number of
-    layers being copied, and matches the
-    slink:VkImageSubresourceLayers.layerCount of the 2D image (internal
-    issue 1152).
-  * Rephrase memory / control barrier rules in the
-    <<spirvenv-module-validation, Validation Rules within a Module>> section
-    to avoid "`not use none`", which could be misconstrued to allow no
-    synchronization semantics, and only storage class semantics (internal
-    issue 1154).
-
-Other Issues:
-
-  * Move GLSL extension specifications to the KhronosGroup/GLSL repository
-    on Github.
-  * Add missing description of ename:VK_FILTER_CUBIC_IMG enum to
-    slink:VkFilter.
-  * Update description of code:PrimitiveId in the
-    <<interfaces-builtin-variables,Built-In Variables>> section to clarify
-    its behavior.
-  * Disallow disjoint images from being used with dedicated-memory images in
-    slink:VkMemoryDedicatedAllocateInfoKHR.
-  * Update README to suggest older versions of "mathematical" and
-    "ruby-gems" packages for use on Cygwin.
-  * Fix typos
-
-New Extensions:
-
-  * `VK_AMD_buffer_marker`
-
------------------------------------------------------
-
-Change log for January 15, 2018 Vulkan 1.0.68 spec update:
-
-  * Bump API patch number and header version number to 68 for this update.
-
-Github Issues:
-
-  * Added more details in the
-    <<extended-functionality-extensions-compatibility, Extension
-    Compatibility>> section, allowing explicit incompatibilities, and
-    simplify corresponding language in the style guide, which now defers to
-    the API Specification on this point (public issue 638).
-  * Fix typo in description of slink:VkCommandBufferLevel::pname:level
-    (public issue 651).
-  * Only include extension-dependent valid usage statement for
-    slink:VkImageSubresourceRange, and note that the extension names for
-    header files described in the <<boilerplate-wsi-header, Window
-    System-Specific Header Control>> section are only valid links, when the
-    specification being viewed is built with the corresponding extensions
-    enabled (public issue 652).
-
-Internal Issues:
-
-  * Add language to elink:VkResult specifying that when commands return an
-    error, output parameter contents are undefined instead of unmodified
-    (except for pname:sType and pname:pNext). Note that this is a behavior
-    change. Add notes calling out slink:VkImageFormatProperties as an
-    exception (internal issue 1118).
-  * Add "`general-purpose`" to the style guide, and correct existing uses of
-    "`general purpose`" as an adjective (internal issue 1121).
-  * Add the ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT_EXT token
-    for the `VK_EXT_validation_cache` extension, following the same naming
-    pattern as other tokens in the extension, but keep the old
-    ename:VK_DEBUG_REPORT_OBJECT_TYPE_VALIDATION_CACHE_EXT token around for
-    backwards compatibility (internal issue 1126).
-
-Other Issues:
-
-  * Specify that flink:vkCmdSetDiscardRectangleEXT does not affect copies or
-    clears, matching existing language for the scissor rectangle test.
-  * Move the <<boilerplate-sType, pname:sType>> definition from the
-    boilerplate appendix to the Fundamentals chapter, putting it together
-    with the valid usage of pname:sType rather than having the definition
-    split across two places.
-  * Inline all of the etext:Vk*Flags definitions, moving each one from the
-    boilerplate appendix to appear either after the corresponding
-    etext:Vk*FlagBits value if one is defined, or after the first structure
-    that includes them if not.
-
------------------------------------------------------
-
-Change log for January 5, 2018 Vulkan 1.0.67 spec update:
-
-  * Bump API patch number and header version number to 67 for this update.
-  * Update copyright dates to 2018
-
-Github Issues:
-
-  * Fix texture lookup functions in `GL_KHR_vulkan_glsl` specification
-    (public pull request 363).
-  * Clarify the state waited semaphores are left in when a call to
-    flink:vkQueuePresentKHR fails (public issue 572).
-  * Cleanup descriptions of slink:VkObjectTablePushConstantEntryNVX and
-    slink:VkObjectTableDescriptorSetEntryNVX (public issue 583)
-  * Remove redundant flink:vkCmdSetDiscardRectangleEXT valid usage
-    statements (public pull 586).
-  * Make dynamic state array length valid usage statements implicit for
-    flink:vkCmdSetViewportWScalingNV, flink:vkCmdSetDiscardRectangleEXT, and
-    flink:vkCmdSetViewport (public pull 589).
-  * Clarify meaning of window extent (0,0) in slink:VkSwapchainKHR for the
-    Windows and X11 platforms, in their respective extensions (public issue
-    590).
-  * Allow flink:vkGetPastPresentationTimingGOOGLE to return
-    ename:VK_INCOMPLETE (public issue 604).
-  * Add synchronization valid usage statements to flink:vkAcquireNextImage
-    (public pull 611).
-  * Fix some broken external links and internal xrefs (public pull 613).
-  * Clean up slink:VkViewport valid usage statements in the presence or
-    absence of relevant extensions (public pull 623).
-  * Remove
-    ename:VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL_KHR
-    token from VK_KHR_maintenance2 from the non-extension VU path for
-    slink:VkGraphicsPipelineCreateInfo (public issue 628).
-  * Miscellaneous minor markup fixes - extension name strings (public pull
-    631), Notes (pull 633), queue names emitted by generator scripts (pull
-    634), block formatting in slink:VkDescriptorUpdateTemplateEntryKHR (pull
-    635), ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_IMG (pull
-    641), quotes and apostrophes (pull 643),
-  * Miscellaneous minor grammar fixes (public pull 644).
-  * Fix markup macros so usage like ptext:*Src* works (public pull 647).
-
-Internal Issues:
-
-  * Clarify in the `VK_KHR_surface` and `VK_KHR_swapchain` extensions that
-    parameter combinations which aren't supported for normal images are also
-    unsupported for presentable images, even if the parameter values are
-    individually supported as reported by the surface capability queries
-    (internal issue 1029).
-  * Fixed XML typo in the valid value field of the pname:sType member of
-    slink:VkPhysicalDeviceExternalMemoryHostPropertiesEXT (internal issue
-    1100).
-
-Other Issues:
-
-  * Add memory semantics validity rules to the <<spirvenv-module-validation,
-    Validation Rules within a Module>> section of the SPIR-V environment
-    appendix, and specify that sequentiality consistency is not supported.
-    This forbids certain cases like "`Load+Release`" that we don't expect to
-    ever be meaningful.
-  * Document mapping of OpenGL Shading Language barriers to SPIR-V scope and
-    semantics in the `GL_KHR_vulkan_glsl` specification.
-
-New Extensions:
-
-  * `VK_EXT_conservative_rasterization`

-Change log for November 27, 2017 Vulkan 1.0.66 spec update:
-
-  * Bump API patch number and header version number to 66 for this update.
-
-Github Issues:
-
-  * Clarified how and when ename:VK_ERROR_TOO_MANY_OBJECTS is generated in
-    flink:vkAllocate Memory, and remove incorrect valid usage statement
-    about exceeding the API limit (public issue 356).
-  * Minor clarification of the description of
-    flink:vkUpdateDescriptorSetWithTemplateKHR::pname:descriptorUpdateTemplate
-    (public issue 564).
-  * Minor fixes for flink:vkCmdSetViewportWScalingNV (public pull request
-    588).
-  * Fix random name markup issues (public pull request 603).
-  * Fix code:BuiltIn decoration typo in the <<fxvertex-attrib, Vertex
-    Attributes>> section (public pull request 606).
-  * Fix synchronization language following the definition of
-    flink:vkAcquireNextImageKHR (public issue 607).
-  * Restore descriptions of several commands and structures missing from the
-    generated spec due to a mistyped asciidoctor conditional (public issue
-    612).
-  * Fix 1.0.41 changelog to refer to public issues 403/404 (public issue
-    618).
-
-Internal Issues:
-
-  * Refactor valid usage statements with internal conditionals in
-    `copies.txt`, `pipelines.txt`, `renderpass.txt`, and `resources.txt` so
-    each branch of the conditional appears as a standalone statement which
-    can contain a separate VUID. This should have no impact on the generated
-    specs, but is necessary given the present state of the VU extractor and
-    the validation layer code that consumes them (internal issue 1043).
-  * Fix VkQueueGlobalPriorityEXT enum values missing _EXT suffix (internal
-    issue 1045).
-  * Clarified initial ownership of resources bound to shared memory objects,
-    (internal issue 1068).
-  * Fix duplicated valid usage ID tag for flink:vkCmdCopyImage, and make the
-    required layouts include ename:VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL in
-    both cases (internal issue 1084).
-
-Other Issues:
-
-  * Remove the noise functions from GLSL for SPIR-V for Vulkan in the
-    `GL_KHR_vulkan_glsl.txt` extension.
-
-New Extensions:
-
-  * `VK_EXT_external_memory_host`
-  * `VK_EXT_external_memory_dma_buf`
-  * `VK_EXT_queue_family_foreign`

-Change log for October 27, 2017 Vulkan 1.0.65 spec update:
-
-  * Bump API patch number and header version number to 65 for this update.
-
-Github Issues:
-
-  * Replaced inaccurate "`pixel`" with "`texel`" or "`compressed texel
-    block`" as appropriate in the <<sparsememory, Sparse Resources>> chapter
-    (public issue 86).
-  * Attempt to clarify security/integrity guarantees in the
-    <<fundamentals-errors, Errors>> section (public issue 147).
-  * Update the <<memory-device,Device Memory>> section with clarifications
-    and markup fixes (public pull request 194).
-  * Fix typo VkDeviceCreateInfo -> slink:VkDebugMarkerObjectNameInfoEXT in
-    sample code for `VK_EXT_debug_marker` extension (public pull request
-    227).
-  * Clarified slink:VkFramebufferCreateInfo language regarding concurrent
-    use of attachment resources during a render pass instance (public issue
-    299).
-  * Added overlap rules for destination regions in <<copies,copy commands>>.
-    Also unified the sparse and non-sparse source-destination overlap rules,
-    since the non-sparse rules were technically inaccurate in the face of
-    aliasing in flink:vkBindMemory2 - the new rules are true regardless
-    (public issue 317).
-  * Clarified the <<features-features-samplerAnisotropy,
-    pname:samplerAnisotropy feature>> to only affect the
-    slink:VkSamplerCreateInfo::pname:anisotropyEnable value, and that
-    pname:maxAnisotropy is ignored when pname:anisotropyEnable is VK_FALSE
-    (public issue 503).
-  * Clarify pointer valid usage statements to use "`valid pointer to valid
-    _object_`" terminology and update the
-    <<fundamentals-validusage-pointers,Valid Usage for Pointers>> section
-    accordingly (public pull request 547).
-  * Some operations that use integer coordinates can also accept a LOD to
-    sample from. Add a description of that selection and the validity
-    conditions in the new <<textures-integer-coordinate-operations, Integer
-    Texel Coordinate Operations>> section (public issue 548).
-  * Update stext:VkImageSubresource* valid usage statements (public pull
-    request 550).
-  * Added text tying ename:VK_OUT_OF_POOL_MEMORY error for
-    flink:vkAllocateDescriptorSets to the number of descriptor types in the
-    allocating pool. Removed redundant "`length`" text about number of
-    descriptors returned (public issue 582).
-  * Update slink:VkSwapchainCreateInfoKHR descriptions (public pull request
-    585).
-  * Update slink:VkPipelineViewportWScalingStateCreateInfoNV and related
-    structures' valid usage statements (public pull request 587).
-  * Change some dates to conform to ISO 8601 as specified in the style guide
-    (public pull request 601).
-  * Fix some math markup problems and be more consistent in use of asciidoc
-    math markup (public pull request 602).
-
-Internal Issues:
-
-  * Clarified that attribute reads from incomplete vertex buffer elements
-    are considered out of bounds accesses, in the
-    slink:VkPhysicalDeviceFeatures and flink:vkCmdBindVertexBuffers.txt
-    sections (internal issue 842).
-
------------------------------------------------------
-
-Change log for October 20, 2017 Vulkan 1.0.64 spec update:
-
-  * Bump API patch number and header version number to 64 for this update.

-    status to etext:VK_ERROR_DEVICE_LOST (public pull request 502).
-  * Fix description of the tlink:PFN_vkDebugReportCallbackEXT debug report
-    callback function pointer to match the validation layer behavior (public
-    issue 534).
-  * Document experimental KHX extensions and alternate vendor author IDs
-    also ending in X in more detail in the <<extensions, Layers &
-    Extensions>> appendix, the extensions section of the style guide, and
-    the registry schema description document (public issues 536, 580).
-  * Fix references to ptext:pDepthStencil to properly refer to
-    pname:pDepthStencilState or pname:pRasterizationState as appropriate in
-    the slink:VkGraphicsPipelineCreateInfo description (public issue 542).
-  * Fix wrong parameter name in slink:VkPipelineMultisampleStateCreateInfo
-    valid usage (public pull request 571).
-
-Internal Issues:
-
-  * Update the style guide to describe how to write LaTeX math expressions
-    in table cells (internal issue 908).
-  * Define how framebuffer-local dependencies work between subpasses with
-    the same or different numbers of samples, in the
-    slink:VkSubpassDescription and <<synchronization-framebuffer-regions,
-    Framebuffer Region Dependencies>> sections. This clarifies which samples
-    in an input attachment you are allowed to access after a
-    framebuffer-local dependency (internal issue 915).
-  * Specify which storage classes can have an initializer in the
-    <<spirvenv-module-validation, Validation Rules within a Module>> section
-    (internal issue 1023).
-  * Use "LOD" consistently for "level-of-detail", to eliminate spelling
-    inconsistencies. The term is already standardized in the Glossary
-    (internal issue 1027).
-
-Other Issues:
-
-  * Fix false positives in Makefile dependencies when rules fail, by
-    deleting partially-made targets.
-
-New Extensions:
-
-  * `VK_AMD_shader_info`
-
------------------------------------------------------
-
-Change log for October 13, 2017 Vulkan 1.0.63 spec update:
-
-  * Bump API patch number and header version number to 63 for this update.
-
-Github Issues:
-
-  * Add missing valid usage statements for ptext:maxDescriptorSets*,
-    ptext:maxPerStageDescriptorInputAttachments, and
-    ptext:maxPerStageResources to slink:VkPipelineLayoutCreateInfo.txt,
-    flink:VkComputePipelineCreateInfo, and
-    flink:VkGraphicsPipelineCreateInfo (public issue 546).
-  * Fix typos in ftext:vkCmdDraw*AMD descriptions (public pull request 549).
-  * Fixed flink:vkCmdWriteTimestamp so it is not unnecessarily restricted to
-    queues supporting graphics or compute operations (public issue 558).
-  * Improvements to valid usage generator for output `*Flags` pointer
-    parameters and for some `void *` parameters (public pull requests 560,
-    562).
-  * Document `altlen` attribute in XML schema as valid C99 syntax and tweak
-    `vk.xml` to match (public pull request 566).
-  * Clarify when pname:fence is signaled by flink:vkQueueSubmit in a more
-    obvious place (public issue 577).
-
-Internal Issues:
-
-  * Specify a list of supported SPIR-V Storage Classes in the
-    <<spirvenv-module-validation, Validation Rules within a Module>>
-    appendix (internal SPIR-V issue 166).
-  * Relax the shared semaphore wait timeout requirement in the
-    <<synchronization-semaphores-importing, Importing Semaphore Payloads>>
-    section (internal issue 820).
-  * Update the <<textures-image-level-selection, Image Level(s) Selection>>
-    equations so that the parameters returned by the level-of-detail query
-    appear explicitly, also fixing the issue that linear filtering would
-    select a level below the base level for magnification (internal issue
-    926).
-  * Disallow creation of a swapchain with zero pname:imageExtent in
-    slink:VkSurfaceCapabilitiesKHR and slink:VkSwapchainCreateInfoKHR
-    (internal issue 1020).
-
-Other Issues:
-
-  * Clarify in <<textures-operation-validation,Image View Validation>> that
-    the layout of subresources in an image view must have a layout that
-    matches that written into the descriptor, and that this section is about
-    validating image views, not images.
-
-New Extensions:
-
-  * `VK_EXT_global_priority`
-
------------------------------------------------------
-
-Change log for October 6, 2017 Vulkan 1.0.62 spec update:
-
-  * Bump API patch number and header version number to 62 for this update.
-
-Github Issues:
-
-  * Move asciidoc conditionals for `VK_KHR_maintenance1` in
-    slink:VkDescriptorSetAllocateInfo so valid usage statements for
-    `VK_KHR_push_descriptor` aren't accidentally removed when the first
-    extension isn't enabled (public issue 573).
-
-Internal Issues:
-
-  * Specify constraints on concurrent access to fences that share payload in
-    the <<synchronization-fences-importing, Importing Fence Payloads>> and
-    <<synchronization-semaphores-waiting-state, Semaphore State Requirements
-    For Wait Operations>> sections (internal issue 820).
-  * Define the term "`retired swapchain`", reorganize some swapchain
-    language, and improve language for pname:oldSwapchain in
-    flink:VkSwapchainCreateInfoKHR, the <<swapchain-wsi-image-create-info>>
-    table, flink:vkDestroySwapchainKHR, and flink:vkAcquireNextImage2KHX
-    (internal issue 869).
-  * Describe in the <<writing-arrays, Describing Properties of Array
-    Elements>> section of the style guide how and when to use "`each`" and
-    "`any`" to refer to properties of array elements, and make those uses in
-    the specification consistent (internal issue 884).
-  * Clarified that events cannot be used for cross-queue synchronization in
-    the <<synchronization-events, Events>> section and for
-    flink:vkCmdWaitEvents (internal issue 970).
-  * Add success and error codes to +vk.xml+ for
-    flink:vkCreateValidationCacheEXT (internal issue 995).
-  * Clarify aspect mask usage for image memory barriers of multi-plane
-    images in slink:VkImageSubresourceRange, slink:VkImageMemoryBarrier, and
-    the <<textures-layout-validation, Layout Validation>> section (internal
-    issue 996).
-
-Other Issues:

-    pname:pPostSubpassSampleLocations).
-  * Add missing buffer usage requirements for indirect draws in
-    flink:vkCmdDrawIndirect, flink:vkCmdDrawIndirectCountAMD,
-    flink:vkCmdDrawIndexedIndirect, and
-    flink:vkCmdDrawIndexedIndirectCountAMD.
-  * Modify Makefile to allow specification to build in git "`detached HEAD`"
-    state.
-  * Update valid usage ID generation script to allow recursively operating
-    on all `.txt` files in a specified directory, and move the `startVUID`
-    tracking information into a separate python file that is automatically
-    updated by the script.
-  * Fixed errors in API example code for
-    flink:vkUpdateDescriptorSetWithTemplateKHR and
-    flink:vkCmdPushDescriptorSetWithTemplateKHR.
-
-New Extensions:

-Change log for September 15, 2017 Vulkan 1.0.61 spec update:
-
-  * Bump API patch number and header version number to 61 for this update.
-
-Github Issues:
-
-  * Provide alternate length attributes (altlen=) in the XML schema, for
-    those using length attributes to generate code instead of documentation
-    (public issue 555).
-  * Fix erroneous references to `latex:` being used for asciidoc math
-    markup, rather than `latexmath:` (public pull request 556).
-  * Add author ID to XML for Kazan software renderer (public pull request
-    557).
-
-Internal Issues:
-
-  * Add the <<fundamentals-abi,Application Binary Interface>> section
-    describing platform ABI requirements and recommendations, add examples
-    of function and function pointer declarations to the
-    <<boilerplate-platform-specific-calling-conventions, Platform-Specific
-    Calling Conventions>> section, and remove related language that existed
-    elsewhere in the specification (internal issue 64).
-  * Describe where to document valid usage interactions of chained
-    structures in the style guide, and fix one case now appearing in
-    slink:VkBufferCreateInfo instead of the child
-    slink:VkDedicatedAllocationBufferCreateInfoNV structure (internal issue
-    715).
-  * Add example to the style guide of describing enumerated types which are
-    empty when the spec is built without relevant extensions enabled, and
-    apply it to existing examples for
-    elink:VkDescriptorSetLayoutCreateFlagBits and
-    elink:VkSubpassDescriptionFlagBits (internal issue 864).
-  * Add a note to the <<fundamentals-validusage-enums, Valid Usage for
-    Enumerated Types>> section that the special values suffixed with
-    etext:_BEGIN_RANGE, etext:_END_RANGE, etext:_RANGE_SIZE and
-    etext:_MAX_ENUM are not part of the API and should: not be used by
-    applications (internal issue 872).
-  * Added note to flink:vkCmdUpdateBuffers explaining the performance
-    penalty for copies done in this way, and why the upper copy limit is
-    what it is (internal issue 952).
-  * Update `VK_KHX_device_group` to split some functionality into the new
-    `VK_KHR_bind_memory2` extension, and rename that functionality (internal
-    issue 969).
-  * Remove *Status* fields from extension appendices, since they are by
-    definition published and complete by the time they reach the public
-    github repository (internal issue 973).
-
-Other Issues:
-
-  * Update Data Format specification dependency to version 1.2 and change
-    references to DF sections accordingly.
-  * Update XML to make the pname:pAllocator parameter of
-    flink:vkRegisterDeviceEventEXT and flink:vkRegisterDisplayEventEXT in

-
-Github Issues:
-
-  * Document that <<queries-timestamps, Timestamp Queries>> can only be
-    meaningfully compared when they are written from the same queue (public
-    issue 216).
-  * Document that the `<extension>` tag `type` attribute is required for
-    non-disabled extensions (derived from, but does not close public issue
-    354).
-  * Clean up registry schema length attribute descriptions to be consistent
-    and correct (public issue 555).
-
-Internal Issues:
-
-  * Replace as much of the hand-written extension appendix metadata as
-    possible with asciidoc includes generated from corresponding attributes
-    of +vk.xml+, and enhance the style guide to match. This avoids
-    inconsistencies between +vk.xml+ and the appendices, and produces a more
-    uniform style (internal issue 137).
-  * Remove the generated extDependency.{py,sh} files from the tree and
-    create them dynamically on demand instead, reducing merge conflicts
-    (internal issue 713).
-  * Add a prototype tool for generating in-place difference markup for
-    sections guarded by asciidoc conditionals, and new syntax for open
-    blocks to support it (internal issue 833).
-  * Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle
-    types to the same physical device in the
-    slink:VkPhysicalDeviceIDPropertiesKHR,
-    flink:VkImportMemoryWin32HandleInfoKHR,

-    <<external-fence-handle-types-compatibility, External fence handle types
-    compatibility>> sections (internal issue 956).
-
-Other Issues:
-
-  * Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there
-    is an interaction, but not a strict dependency), and add a new
-    `extension` attribute to the `<require` XML tag to allow classifying a
-    subset of interfaces of an extension as requiring another extension.
-    Update the registry schema and documentation accordingly.
-
-New Extensions:
-
-  * `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask`

-
-Github Issues:
-
-  * Fix a few missing Implicit Valid Usage statements to indicate that a
-    common parent of two objects is required (public issue 497).
-  * Clarify render pass synchronization language for
-    slink:VkSubpassDependency and <<renderpass,render passes>> (public
-    issue 531).
-  * Rename ename:VK_STRUCTURE_TYPE_SURFACE_CAPABILITIES2_EXT to
-    ename:VK_STRUCTURE_TYPE_SURFACE_CAPABILITIES_2_EXT for consistency, and
-    add an alias for backwards compatibility (public issue 539).
-
-Internal Issues:
-
-  * Add an explanation to the <<interfaces-builtin-variables-layer,
-    code:Layer>> description explaining that writing to invalid layers
-    results may or may not result in primitives being processed and fragment
-    shaders being run, and gives undefined results in the framebuffer
-    (internal issue 614)
-  * Add valid usage statement for slink:VkDescriptorSetLayoutBinding
-    requiring that input attachment descriptor bindings must not use
-    non-fragment stages (internal issue 933).
-
-Other Issues:
-
-  * Makes description of pname:loadOp and pname:storeOp easier to read in
-    the <<renderpass-load-store-ops>> section.

-
-Change log for August 14, 2017 Vulkan 1.0.58 spec update:
-
-  * Bump API patch number and header version number to 58 for this update.
-
-Github Issues:
-
-  * Update the <<interfaces-resources-descset,Descriptor Set Interface>>
-    section to allow multiple variables with the same descriptor set/binding
-    decorations, and require that all variables that are statically used
-    must be consistent with the pipeline layout. Allow
-    ename:VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER to be used with texture
-    and sampler variables (public issues 522, 524).
-
-Internal Issues:
-
-  * Replace networkx package used for extension dependency generation with a
-    homegrown network dependency traverser (internal issue 713).
-  * Specify in the <<interfaces-fragmentoutput, Fragment Output Interface>>
-    section that if a fragment shader writes integers that cannot be
-    represented in the format of the colour attachment, then the result is
-    undefined (internal issue 893).
-  * Separate malformed valid usage statement for
-    slink:VkPipelineRasterizationStateCreateInfo into two (internal issue
-    918).
-  * Fix cases where the term 'pNext chain' is incorrectly used in reference
-    to functions, rather than their parameters. Replace 'pNext list' with
-    'pNext chain'. Fixed typo in the example code of
-    +VK_KHR_dedicated_allocation+ (internal issue 944).
-  * Fix typo in elink:VkExternalSemaphoreHandleTypeFlagBitsKHR enum
-    descriptions, replacing
-    etext:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_FENCE_FD_BIT_KHR with
-    ename:VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT_KHR, and make the
-    description more consistent with
-    VK_EXTERNAL_FENCE_HANDLE_TYPE_SYNC_FD_BIT_KHR (internal issue 950).
-
-Other Issues:
-
-  * Clarify how pipeline stage masks affect
-    <<synchronization-pipeline-stages-masks, access and synchronization
-    scopes>>.
-  * Clarify that dedicated allocations do not allow aliasing in the
-    flink:vkBindBufferMemory and flink:vkBindImageMemory valid usage
-    statements.
-  * Correct specification of pname:dynamicCount for push_constant token in
-    slink:VkIndirectCommandsLayoutNVX.

-  * Update documentation of ename:VK_PIPELINE_CREATE_ALLOW_DERIVATIVES_BIT
-    to explicitly mention both graphics and compute pipelines (public issue

-
-Internal Issues:
-
-  * Document that
-    slink:VkPhysicalDeviceLimits::pname:framebufferColorSampleCounts does
-    not cover integer formats (internal issue 550).
-  * Add a note under slink:VkImageViewCreateInfo describing how values meant
-    for one format can be sanitized when used via another format (internal
-    issue 927).
-  * Add valid usage statements to ftext:vkCmd* documenting that image
-    subresources used as attachments must not be accessed as non-attachments

-
-  * Bump API patch number and header version number to 56 for this update.
-
-Github Issues:
-
-  * Add valid usage statements for commands introduced by
-    `VK_EXT_debug_report` and `VK_EXT_debug_marker` extensions, regarding
-    the valid pname:object and pname:objectType values (public issue 495).
-  * Modify `GL_KHR_vulkan_glsl` specification to document that uniform and
-    buffer block arrays each take only a single binding (public issue 514).
-  * Add `KHX` author tag to +vk.xml+ (public issue 526).
-
-Internal Issues:
-
-  * Document use of code: macro for non-Vulkan APIs in the style guide
-    (internal issue 863).
-  * Document that reference page open block delimiters must not contain
-    asciidoc section markup in the style guide (internal issue 898).
-  * Fix <<spirvenv,SPIR-V appendix>> to say
-    code:VariablePointersStorageBuffer instead of
-    code:VariablePointersUniformBufferBlock (internal issue 928).
-
-Other Commits:
-

-Change log for July 15, 2017 Vulkan 1.0.55 spec update:
-
-  * Bump API patch number and header version number to 55 for this update.
-
-Github Issues:
-
-  * Removed unintended optional parameter in +vk.xml+ from the
-    pname:pWaitSemaphores member of slink:VkPresentInfoKHR, which resulted
-    in the generation of an incorrect implicit valid usage clause allowing
-    pname:pWaitSemaphores to be NULL even when pname:waitSemaphoreCount is
-    non-zero (public issue 491).
-  * Add missing attribute to +vk.xml+ documenting that
-    slink:VkSwapchainCounterCreateInfoEXT extends
-    slink:VkSwapchainCreateInfo (public issue 510).
-  * Add const qualifier for some `VK_EXT_debug_market` extension command
-    parameters that were missing it (public issue 513).
-  * Fix definition of q and level~base~ in
-    <<textures-image-level-selection,Image Level(s) Selection>> (public
-    issue 515).
-  * Clarify lifetime requirement for slink:VkRenderPass objects used in
-    object creation (public issue 516).
-  * Fix link to floating/normalized fixed-point conversion from
-    <<interfaces-fragmentoutput,Fragment Output Interface>> (public issue
-    521).
-
-Internal Issues:
-
-  * Update the style guide to include the general structure of a Vulkan
-    command name, the specific rule for using "`Get`" vs. "`Enumerate`" in
-    names, and a table of verbs commonly used in command names (spinoff of
-    internal issue 753).
-  * Clarified the behavior of automatic layout transitions in case of
-    attachment views that are 2D or 2D array views of 3D images. In
-    addition, restructured the valid usage clauses corresponding to the
-    members of the slink:VkImageSubresourceRange structure and added missing
-    valid usage clauses for its pname:baseMipLevel and pname:baseArrayLayer
-    members (internal issues 803, 849).
-  * Modify `GL_KHR_vulkan_glsl` specification to allow explicit std430 on a
-    push_constant declaration (internal issue 919).
-
-Other Commits:
-
-  * Modify <<synchronization-framebuffer-regions, Framebuffer Region
-    Dependencies>> to use synchronization scope terminology.
-  * Add ename:VK_COLOR_SPACE_EXTENDED_SRGB_NONLINEAR_EXT to the
-    `VK_EXT_swapchain_colorspace` extension.
-  * Replace XML comments with `comment` attributes and/or tags, to enable
-    tools which transform the XML without loss of information.
-  * Replace `validextensionstructs` with `structextends`, which is tagged in
-    the child structure instead of the parent. This makes it slightly
-    simpler to add new structs to the XML, causes fewer merge conflicts, and
-    the information is kept localized to the extension structures where it
-    belongs. The old `validextensionstructs` attributes will be retained
-    until we're certain this doesn't cause problems with known consumers of
-    +vk.xml+.

-    language. CTS and all implementations were already doing this, it was
-    just a documentation bug that it was flipped to lower-left (internal
-    issue 603).
-  * Add a section to the style guide describing how VUID tags are changed
-    and removed when the corresponding Valid Usage statements are modified
-    (internal issue 829).

-
-Github Issues:
-
-Internal Issues:
-
-  * Clarify mappings of coordinates for mutable, compatible image views in
-    slink:VkImageViewCreateInfo (internal issue 815).
-  * Make ename:VK_BIND_SFR_BIT require a logical device with multiple
-    physical devices, so that standard sparse image block dimensions are
-    only required on systems that support multi-GPU (internal issue 835).
-  * Convert all files from use of // refBegin .. // refEnd comments to
-    delimit ref pages, to use of open blocks, and update style guide
-    accordingly (internal issue 839).
-  * Add valid usage for slink:VkWriteDescriptorSet when performing updates
-    to a ename:VK_STORAGE_IMAGE descriptor with layout
-    ename:VK_IMAGE_LAYOUT_GENERAL.
-  * Add a hack to the validity generator script to support an odd
-    interaction between flink:vkCmdFillBuffer and an extension (internal
-    issue 853).
-  * Remove redundant text describing slink:VkBufferCreateInfo::pname:usage,
-    which was already covered by implicit valid usage (internal issue 854).
-  * Update implicit validity generator script to properly handle the
-    pname:sType and pname:pNext members of "returnedonly" structures
-    (internal issue 874).
-  * Note that slink:VkApplicationInfo::pname:pApplicationName &
-    slink:VkApplicationInfo::pname:pEngineName are optional, and add missing
-    implicit valid usage statements for flink:vkDestroyInstance.
-  * Added missing valid usage for flink:vkCmdWriteTimestamp to require a

-Internal Issues:
-
-  * Clarify behavior when non-coherent memory has
-    <<memory-device-unmap-does-not-flush, not been flushed before being
-    unmapped>> (internal issue 819).
-  * Fix description of code:WorkgroupSize builtin to note it decorates an
-    object, not a variable (internal issue 836).
-  * Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style
-    equations are rendered properly (internal issue 845).
-  * Add language to the "`Extension Handles, Objects, Enums, and Typedefs`"
-    section of the Procedures and Conventions document stating that any new
-    handle type requires a corresponding entry in the elink:VkObjectType
-    enumerated type (internal issue 856).
-  * Update style guide to use slink macro for Vulkan handle type names, and
-    define narrow conditions under which to use the *name and *text macros
-    instead of *link (internal issue 886).
-  * Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>>
-    extension on VK_KHX_device_group_creation to +vk.xml+ and the extension
-    appendix.
-  * Change the copyright on Vulkan specification asciidoc *source* files to
-    CC-BY 4.0, and update the proprietary Khronos copyright applied to the
-    generated *output* formats (internal issue 327). This enables broader
-    re-use and modification of the Vulkan specification sources, while not

-Change log for June 4, 2017 Vulkan 1.0.51 spec update:
-
-  * Bump API patch number and header version number to 51 for this update.
-
-Github Issues:
-
-  * Add Valid Usage statement to flink:vkCmdResolveImage to require that
-    source and destination image formats match (public issue 492).
-  * Specify that a code:char* parameter must: be a valid null-terminated
-    string in the <<fundamentals-implicit-validity, implicit valid usage>>
-    section (public issue 494).
-  * Removed unnecessary VU for slink:VkPhysicalDeviceFeatures which is
-    covered by ename:VK_ERROR_FEATURE_NOT_PRESENT already (public issue
-    496).
-  * Clarify valid usage of pname:pQueueFamilyIndices in
-    slink:VkBufferCreateInfo, slink:VkImageCreateInfo, and
-    slink:VkSwapchainCreateInfoKHR (public issue 501).
-  * Document that dependencies of enabled extensions must also be enabled in
-    the <<extended-functionality-extensions-dependencies, Extension
-    Dependencies>> section (public issue 507).
-
-Internal Issues:
-
-  * Change slink:VkMappedMemoryRange valid usage to allow pname:offset +
-    pname:size == size of the allocation. Also, if ename:VK_WHOLE_SIZE is
-    used, require the end of the mapping to be aligned to a multiple of
-    pname:nonCoherentAtomSize (internal issue 611).
-  * Add issue to `VK_KHR_win32_surface` about reusing window objects from a
-    different graphics API or Vulkan ICD (internal issue 639).
-  * Require locations on user in/out in `GL_KHR_vulkan_glsl` (internal issue
-    783).
-  * Added version info to the json validation output, and updated the schema
-    to match (internal issue 838).
-  * Restructure enumerated type descriptions separately from the command or
-    structure they are used in, allowing better reference page generation
-    (internal issue 841).
-  * Re-sort extension appendices to be in alphabetical order within each
-    author ID section.
-  * Fix enum naming and clarify behavior for
-    `VK_NVX_device_generated_commands` extension.

-Change log for May 20, 2017 Vulkan 1.0.50 spec update:
-
-  * Bump API patch number and header version number to 50 for this update.
-
-Github Issues:
-
-  * Fix numerous minor issues with the VK_EXT_debug_report extension (public
-    issues 478, 483, 486, 489, 490).
-
-Internal Issues:
-
-  * Update flink:vkAllocateDescriptorSets to specify conditions under which
-    to return ename:VK_ERROR_FRAGMENTED_POOL or
-    ename:VK_ERROR_OUT_OF_POOL_MEMORY instead of
-    out-of-host/out-of-device-memory, and improve the
-    <<fundamentals-errorcodes, description of those errors (internal issue
-    654).
-  * Add a NOTE documenting that flink:vkAcquireNextImageKHR can only signal
-    a single semaphore, and how to deal with that when multiple physical
-    devices in a logical device need to wait on it (internal issue 730).
-  * Improve description of pname:pNext chains of
-    slink:VkPhysicalDeviceImageFormatInfo2KHR and
-    slink:VkImageFormatProperties2KHR (internal issue 814).
-  * Clean up math markup issues in the <<textures, Image Operations>>
-    chapter (internal issue 818).
-  * Update validusage target to use more robust code for preprocessing, by
-    making direct use of Asciidoctor's preprocessor. Added uniqueItems check
-    to JSON vu schema and add clean_validusage target (internal issue 826).
-  * Update style guide to prohibit writing non-self-contained (on a single
-    bullet point) Valid Usage statements, and modify offending Valid Usage
-    statements in the Specification to match, to assist with automatic
-    extraction for the validation layers (internal issue 828).
-  * Add ename:VK_VALIDATION_CHECK_SHADERS_EXT to elink:VkValidationCheckEXT
-    of the `VK_EXT_validation_flags` extension, to selectively disable
-    shader validation.
-  * Remove duplicate valid usage statement for slink:VkImageMemoryBarrier.
-  * Modify reflow.py script to place VUID tag anchors standalone on a line
-    following their corresponding bullet point, and reflow the spec text
-    accordingly (this had been pending since the initial tag deployment).

-
-Change log for May 12, 2017 Vulkan 1.0.49 spec update:
-
-  * Bump API patch number and header version number to 49 for this update.
-
-Github Issues:
-
-  * Modify reference page extraction script to make internal links to spec
-    anchors refer to the core specification instead of being dangling links
-    (public issue 455).
-  * Fix GL_KHR_vulkan_glsl typo and add a nor-normative mapping to the newly
-    published StorageBuffer class (public issue 466).
-  * Both flink:vkEnumerateInstanceExtensionProperties and
-    flink:vkEnumerateDeviceExtensionProperties return
-    ename:VK_ERROR_LAYER_NOT_PRESENT, which covers the error case of an
-    application providing a layer name that wasn't returned by
-    ftext:vkEnumerate{Instance|Device}LayerProperties (public issue 487).
-  * The specification for flink:VkApplicationInfo::apiVersion says that the
-    driver must return ename:VK_ERROR_INCOMPATIBLE_DRIVER in the case that
-    pname:apiVersion specifies a non-supported version. That means that the
-    valid usage should not also state that, and so the VU statement is
-    removed. The VU had language about "`an effective substitute`" that
-    would have been lost, and so it was moved to the pname:apiVersion
-    description (public issue 488).
-
-Internal Issues:
-
-  * Modify implicit validity generator script to assign asciidoc anchors to
-    all valid usage statements it generates, and reflow.py script to insert
-    Valid Usage ID (VUID) tags into the specification source files for
-    explicit valid usage statements. This has no semantic effects on the
-    specification, but will support the validation layer's detection of
-    valid usage violations and allow it to link into the corresponding part
-    of the specification (internal issue 583).
-  * Assign VUID tags to all explicit VU statements and document
-    the process and tag format in the style guide (internal issue 583).
-  * Clarify the rules of whether to structure new functionality as instance
-    extensions, device extensions, or both in the
-    <<extended-functionality-instance-extensions-and-devices, Instance
-    Extensions and Device Extensions>> section (internal issue 749).
-  * Require that SPIR-V run-time arrays are only used with the
-    code:BufferBlock decoration (internal issue 750).
-  * Fix implicit and explicit valid usage statements for
-    slink:VkWriteDescriptorSet::pname:dstSet (internal issue 767)
-  * Fix SPIR-V code sample for ename:VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER
-    in the <<descriptorsets-uniformtexelbuffer, Uniform Texel Buffer>>
-    section (internal issue 770).
-  * Clarify that disabling depth testing also disables depth writes in the
-    <<fragops-ds-state, Depth and Stencil Operations>> section (internal
-    issue 775).
-  * flink:VkDescriptorImageInfo::pname:imageLayout must match the actual
-    imageLayout at the time the image is accessed. This was in the spec
-    text, but needed an associated valid usage statement.
-  * Note that only 32-bit atomic operations are supported in the
-    <<spirvenv-module-validation, Validation Rules within a Module>>
-    section.
-  * Note that code:UniformConstant variables must not have initializers in
-    the <<spirvenv-module-validation, Validation Rules within a Module>>
-    section.
-  * Add a new elink:VkObjectType enumeration to the core API, promoted from
-    elink:VkDebugObjectTypeEXT, since it is used for much more than just the
-    debug_report extension.

-
-Change log for April 8, 2017 Vulkan 1.0.47 spec update:
-
-  * Bump API patch number and header version number to 47 for this update.
-
-Github Issues:
-
-  * Allow <<synchronization-pipeline-barriers-subpass-self-dependencies,
-    self-dependencies>> (also described for slink:VkSubpassDependency) to
-    have earlier stages depend on later stages if all stages are
-    framebuffer-space (public issue 125).
-  * Clarify when pipeline state structures are ignored in the
-    slink:VkGraphicsPipelineCreateInfo strucure, when the tessellation
-    structure must be valid, and remove 'if `NULL`' descriptions from the
-    valid usage statements (public issue 445).
-  * Remove the obsolete "validextensionstructs" attribute for
-    flink:VkPresentRegionsKHR. This caused a pname:pNext valid usage
-    statement to be generated which wasn't consistent with what is stated in
-    the spec (public issue 481).
-
-Internal Issues:
-
-  * Clarify facingness of non-polygon fragments for slink:VkStencilOpState
-    and in the code:FrontFacing <<interfaces-builtin-variables,built-in
-    variable description>>. Define 'facingness' of a fragment as a distinct
-    term from facingness of a polygon (internal issue 662).
-  * Clarify that the texture compression features (e.g.
-    pname:textureCompressionBC) means that all formats of that type
-    (<<features-features-textureCompressionASTC_LDR,ASTC>>,
-    <<features-features-textureCompressionETC2,ETC2>>,
-    <<features-features-textureCompressionBC,BC>>) are supported, and that
-    support for individual formats may: queried separately (internal issue
-    663).
-  * Clarify in the valid usage for slink:VkBindImageMemoryInfoKHX that each
-    SFR rectangle must be a multiple of the sparse block size for each
-    aspect, e.g. in a depth/stencil image using separate depth/stencil
-    planes (internal issue 721).
-  * Re-remove KHX variants of KHR structure types after promotion (internal
-    issue 762).

-Change log for March 31, 2017 Vulkan 1.0.46 spec update:
-
-  * Bump API patch number and header version number to 46 for this update.
-
-Github Issues:
-
-  * Add language to the <<fundamentals-validusage-enums, Valid Usage for
-    Enumerated Types>> section allowing values to be returned from Vulkan
-    that are not present in extensions explicitly enabled by the
-    application, similar to existing language for bit flags in the
-    <<fundamentals-validusage-flags, Valid Usage for Flags>> section (public
-    issue 442).
-  * *Important*: run `gem update --pre asciidoctor-pdf` before trying to
-    build this version of the spec - 1.5.0.alpha15 is required for this
-    change. Removes the monkey patch currently used to draw valid usage
-    blocks across multiple pages which had numerous issues. A fixed version
-    was incorporated into Asciidoctor-PDF for the latest release, so the
-    monkey patch or any variant thereof is no longer required (public issue
-    465).
-
-Internal Issues:
-
-  * Add ename:VK_DEBUG_REPORT_OBJECT_TYPE_DESCRIPTOR_UPDATE_TEMPLATE_KHR_EXT
-    to `VK_EXT_debug_report` extension
-  * Fix ptext:pNext member of
-    slink:VkPhysicalDeviceDiscardRectanglePropertiesEXT to be a non-const
-    pointer. Properties structures return values, so the chain should be
-    non-const.
-  * Explicitly remove gl_NumSamples from the `GL_KHR_vulkan_glsl` extension,
-    against 1.0 (internal issue 612).
-  * Add Valid Usage statements requiring that each structure type valid in a
-    ptext:pNext chain must: not appear more than once in a chain (internal
-    issue 752).
-  * Use ename:VK_USE_PLATFORM_WIN32_KHX in the
-    `VK_KHX_external_memory_win32` extension, rather than etext:_KHR
-    (internal issue 754).

-    its associated display handle (public issue 460).
-  * Correct several cases where the sparse memory feature name
-    pname:residencyNonResidentStrict was written as
-    pname:sparseResidencyNonResidentStrict (public issue 475).
-
-Internal Issues:
-
-  * Fix ptext:pNext member of slink:VkPhysicalDeviceGroupPropertiesKHX to be
-    a non-const pointer. Properties structures return values, so the chain
-    should be non-const.
-  * Clarify definition of memory aliasing to consistently use the terms
-    "linear" and "non-linear" when referring to resources, and define what
-    those terms mean.
-  * Modified XML schema and implicit validity scripts to generate language
-    for all ptext:pNext values in a ptext:pNext chain instead of just the
-    top level struct, and made `noautovalidity` functional for ptext:sType
-    and ptext:pNext (internal issue 535).
-  * Add more detail for BT2020 and scRGB color spaces in
-    `VK_EXT_swapchain_colorspace` extension (internal issue 632).
-  * Add naming rules for Extension Structure Names (structures added to the
-    ptext:pNext chain of a base structure) to the style guide (internal
-    issue 706).
-  * Define the glossary term "ptext:pNext chain", and use it consistently in
-    the spec (internal issue 744).

-  * Better specify VK_DEVICE_LOST behavior around flink:vkQueueSubmit,
-    flink:vkWaitForFences, and flink:vkGetFenceStatus (public issue 423).
-  * Clarify definition of flink:vkGetQueryPoolResults::pname:queryCount
-    (public issue 441).
-  * Simplify and clean up normative language. Remove shall and replace
-    recommend and variants with should wherever possible (public issue 448).
-  * Fix all dangling internal cross-references in the 1.0-extensions
-    specification, and add scripts/checkXrefs to find these in the future
-    (public issue 456).
-  * Reverse order of ChangeLog.txt entries so the most recent version is
-    documented first (public issue 463)
-  * Removes "become invalid" which clashes with invalid state for command
-    buffers. (public issue 467)
-  * Disallowed pending state in spec text for vkResetCommandBuffer, matching
-    valid usage (public issue 468)
-  * Removes sentence describing invalid state "like initial state". (public
-    issue 469)
-  * Disallows begin command buffer from resetting command buffers in the

-  * Removed extra valid usage statement in VkSubmitInfo (public issue 472)
-
-Internal Issues:

-  * Removed the <<VK_KHR_display>> and <<VK_KHR_display_swapchain>> example
-    code from the specification and noted it has been moved to the Vulkan
-    SDK cube demo (internal issue 179).
-  * Reorder VkExternalMemoryHandleTypeFlagBitsNV description (internal issue
-    480).
-  * Clarify than an implementation is

-  * Break Valid Usage statements describing unrelated parameters into
-    separate statements, and add a style guide entry to follow this approach
-    (internal issue 685).
-  * Move valid usage statement for slink:VkImageCreateInfo from spec body to
-    the explicit valid usage block (internal issue 693).
-  * Fix typos in the descriptions of slink:VkDisplaySurfaceCreateInfoKHR,
-    flink:vkCreateDisplayModeKHR, and
-    flink:vkGetDisplayPlaneSupportedDisplaysKHR in the <<display,Presenting
-    Directly to Display Devices>> section (internal issue 698, 704, 716).
-  * Clarified that mandatory depth/stencil formats are only a requirement
-    for 2D images (internal issue 719).
-  * Clarify that variables decorated with DeviceIndex/ViewIndex must be in
-    the Input storage class (internal issue 733).
-  * Work around generator script problem with removal of Unicode literals
-    from Python 3.0-3.2 using `future` package (internal issue 737).
-  * Remove nonexistent structure type enums from vk.xml (internal issue
-    738).
-  * Fix validextensionstructs attributes for structures in the pname:pNext
-    chain for VkPresentInfoKHR, fixing implicit valid usage statements for
-    those structures (internal issue 740).

-Change log for March 10, 2017 Vulkan 1.0.43 spec update:
-
-  * Bump API patch number and header version number to 43 for this update.
-
-Github Issues:
-
-  * Make clearer that color write mask is applied regardless of whether

-    <<framebuffer-color-write-mask,Color Write Mask>> section (public issue
-    241).
-  * Fix public issue 414:
-  ** Added two new command buffer states (invalid, pending), and an explicit
-     "command buffer lifecycle" section to explain them.
-  ** Replaced "pending execution" with "in the pending state".
-  ** Replaced a bunch of "this will invalidate the command buffer" language
-     with "this will move the command buffer to the invalid state", and added
-     validation language for what state those command buffers should be in.
-  ** Added additional validation language about what state a command buffer
-     should be in for various commands that affect it.
-  ** Added invalidation language to destroy commands in the lifetimes section

-Change log for February 27, 2017 Vulkan 1.0.42 spec update:
-
-  * Bump API patch number and header version number to 42 for this update
-    (the first anniversary edition).
-
-Github Issues:
-
-  * Changed asciidoctor macros so cross-page links in the standalone
-    reference pages function properly (public issue 462).
-
-Internal Issues:
-
-  * Clarified host visibility discussion for slink:VkMemoryType,
-    flink:vkInvalidateMappedMemoryRanges, elink:VkAccessFlagBits, and the
-    <<synchronization-framebuffer-regions,Framebuffer Region Dependencies>>
-    section, removing duplicated information and adding a central definition
-    in the access types section (internal issue 552).
-  * Change description of
-    slink:vkGetPhysicalDeviceSurfacePresentModesKHR::pname:pPresentModes to
-    return an array of values, not structures (internal issue 699).
-
-New Extensions:
-
-  * Add a NOTE to the <<extensions,Layers & Extensions>> chapter describing
-    the experimental status of `KHX` extensions.
-  * Add new Khronos, Khronos Experimental, and vendor Vulkan extensions for
-    release at GDC:

-
-Change log for February 17, 2017 Vulkan 1.0.41 spec update:
-
-  * Bump API patch number and header version number to 41 for this update.
-
-Github Issues:
-
-  * Made all uses of `NULL` vs. code:VK_NULL_HANDLE consistent (public issue
-    276).
-  * Clarify render pass compatibility in different usage scenarios (public
-    issues 403 and 404).
-  * Add valid usage statements to slink:VkFramebufferCreateInfo requiring
-    that the width, height, and number of layers of the framebuffer all be
-    nonzero (public issue 432).
-  * Allow `offset` and `align` in any GLSL version for the
-    `GL_KHR_vulkan_glsl` extension (public issue 435).
-  * Specify lifetime of string objects passed to the
-    tlink:PFN_vkDebugReportCallbackEXT user callback in the
-    +VK_EXT_debug_report+ extension (public issue 446).
-  * Fix inter-page links in multi-file reference pages (public issue 454).
-
-Internal Issues:
-
-  * Update valid usage language for slink:VkImageCreateInfo to disallow
-    creating images that have ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT
-    set without other attachment usage bits
-    (ename:VK_IMAGE_USAGE_INPUT_ATTACHMENT_BIT,
-    ename:VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT, or
-    ename:VK_IMAGE_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT) (internal issue 540).
-  * Disable `VK_EXT_swapchain_colorspace` extension until internal issues
-    640 and 661 are mutually resolved.
-  * Allow alternative mipmap level selection when [eq]#lambda == 0.5# during
-    texture <<textures-image-level-selection,Image Level(s) Selection>>
-    (internal issue 680).
-
-Other Issues:
-
-  * Add a clarification to the style guide that the extension revision
-    number is treated as a patch number, so that changes to published
-    extensions should only include bug fixes and spec clarifications.
-
------------------------------------------------------
-
-Change log for February 10, 2017 Vulkan 1.0.40 spec update:
-
-  * Bump API patch number and header version number to 40 for this update.
-  * There is a major build change in this release. We are now using the
-    Ruby-based ``asciidoctor'' implementation, rather than the Python-based
-    ``asciidoc'' implementation, to process the specification. While the
-    actual specification markup changes were minimal, this requires a new
-    set of build tools and a very different installation process, especially
-    because we now use an experimental direct-to-PDF backend for Asciidoctor
-    instead of Docbook->dblatex->PDF. It is no longer possible to build the
-    Specification using asciidoc. See doc/specs/vulkan/README.adoc
-    for some guidance on installing the new toolchain components.
-  * There are some minor rendering issues in the PDF output due to teething
-    problems with the asciidoctor toolchain, especially with mathematical
-    equations. We are aware of these and working on them.
-
-Github Issues:
-
-  * Updated sample code for the <<sparsememory-examples-basic,sparse
-    resource binding example>> (public issue 97).
-  * Modify line and point clipping behavior in the
-    <<vertexpostproc-clipping, Primitive Clipping>> section to allow for
-    pop-free behavior. The ability to check for which behavior is
-    implemented may be added a future feature or extension (public issue
-    113).
-  * Unify the discussions of implicit ordering throughout the spec, in
-    particular in the new sections <<drawing-primitive-order, Primitive
-    Order>>, <<primsrast-order, Rasterization Order>>, and
-    <<synchronization-implicit, Implicit Synchronization Guarantees>>; the
-    discussion of <<synchronization-submission-order, submission order>>;
-    and references elsewhere to these sections (public issue 133).
-  * Clarify <<descriptorsets-compatibility,Pipeline Layout Compatibility>>
-    language and introduce the term ``identically defined'' (public issue
-    164).
-  * Add a dependency to the +VK_EXT_debug_marker+ extension that's needed to
-    reuse the object type enum from +VK_EXT_debug_report+, and moves the
-    definition of that enum into +VK_EXT_debug_report+ where it should be
-    (public issue 409).
-  * Remove redundant valid usage statement from slink:VkImageBlit (public
-    issue 421).
-  * Update GL_KHR_vulkan_glsl to allow the ternary operator to result in a
-    specialization constant (public issue 424).
-  * Fix valid usage for flink:VkPipelineShaderStageCreateInfo (public issue
-    426).
-  * Correct typo in New Objects list for <<VK_EXT_debug_report>> (public
-    issue 447).
-
-Internal Issues:
-
-  * Moved to asciidoctor for spec builds (internal issue 121).
-  * Update style guide to describe where to put new extensions-specific
-    asciidoc files, and what to name them (internal issue 626).
-  * Add src/spec/indexExt.py to autogenerate registry index entries linking
-    into the 1.0-extensions specification, instead of maintaining the index
-    manually. (internal issue 642).
-  * Autogenerate extension dependencies and lists of all extensions and all
-    KHR extensions from the "supported" attributes in +vk.xml+. Execute
-    +make config/extDependency.sh+ from +doc/specs/vulkan+ when a supported
-    extension is added to vk.xml, to regenerate the dependency script. The
-    consequence is that specifying a single extension to the +makeExt+
-    script will automatically enable all extensions it depends on as well,
-    and that the +makeAllExts+ and +makeKHR+ scripts do not need to be
-    updated when a new extension is supported (internal issue 648).
-  * Put extension appendices all at the same asciidoc section level, so KHR
-    WSI extensions show up in the HTML index (internal issue 648).
-
-Other Issues:
-
-  * Imbed images in the generated HTML specs instead of loading them from
-    the images/ directory.
-  * Fix missing EXT in extension name
-    (ename:VK_EXT_SWAPCHAIN_COLOR_SPACE_EXTENSION_NAME).
-  * Add new +VK_EXT_SMPTE_2086_metadata+ extension.
-  * In the <<platformCreateSurface_xlib,Xlib Surface>> section of the
-    `VK_KHR_xlib_surface` specification, add language warning users that
-    they always need to call code:XinitThreads.
-  * Use the term "presentable image" (rather than "swapchain image")
-    consistently in `VK_KHR_swapchain` and related extensions, and add a
-    glossary term defining it.
-  * Relocate the valid usage for samples of
-    flink:vkGetPhysicalDeviceSparseImageFormatProperties2KHR::pname:pFormatInfo
-    to be below the flink:VkPhysicalDeviceSparseImageFormatInfo2KHR
-    structure.
-
------------------------------------------------------
-
-Change log for January 23, 2017 Vulkan 1.0.39 spec update:
-
-  * Bump API patch number and header version number to 39 for this update.
-
-Github Issues:
-
-  * Clarified that only accesses via the specified buffer/image subresource
-    ranges are included in the access scopes (public issue 306).
-  * Add missing valid usage statements for flink:vkCreateComputePipelines
-    and flink:vkCreateGraphicsPipelines (public issue 427).
-
-Internal Issues:
-
-  * Add a Note to the <<invariance,Invariance>> appendix about a difference
-    between OpenGL and Vulkan with regards to how primitives derived from
-    offsets are handled (internal issue 355).
-  * Add the +<<VK_KHR_get_physical_device_properties2>>+,
-    +<<VK_KHR_maintenance1>>+, and +<<VK_KHR_shader_draw_parameters>>+
-    extensions (internal issue 448).
-  * Add the +<<VK_EXT_shader_subgroup_vote>>+ and
-    +<<VK_EXT_shader_subgroup_ballot>>+ extensions (internal issue 449).
-  * Update the texture level-of-detail equation in the
-    <<textures-scale-factor,Scale Factor Operation>> section to better
-    approximate the ellipse major and minor axes (internal issue 547).
-  * Forbid non-explicitly allowed uses of interface decorations in the
-    introduction to the <<interfaces,Shader Interfaces>> chapter (internal
-    issue 607).
-  * Replace use of MathJax with KaTeX, for improved load-time performance as
-    well as avoiding the scrolling-and-scrolling behavior due to MathJax
-    asynchronous rendering when loading at an anchor inside the spec. This
-    change also requires moving to HTML5 output for the spec instead of
-    XHTML, and there is a visible difference in that the chapter navigation
-    index is now in a scrollable sidebar instead of at the top of the
-    document. We may or may not retain the nav sidebar based on feedback
-    (internal issue 613).
-  * Improve consistency of markup and formatting in extension appendices
-    (internal issue 631).
-
-Other Issues:
-
-  * Add explicit valid usage statements to slink:VkImageCopy requiring that
-    the source and destination layer ranges be contained in their respective
-    source and destination images.
-  * Add valid usage language for swapchain of flink:vkAcquireNextImage. If
-    the swapchain has been replaced, then it should not be passed to
-    flink:vkAcquireNextImage.
-  * Add a valid usage statement to flink:vkCreateImageView, that the image
-    must have been created with an appropriate usage bit set.
-  * Noted that slink:VkDisplayPresentInfoKHR is a valid extension of
-    slink:VkPresentInfoKHR in the <<wsi_swapchain,WSI Swapchain>> section.
-  * Update valid usage for flink:vkCmdSetViewport and flink:vkCmdSetScissor
-    to account for the multiple viewport feature. If the feature is not
-    enabled, the parameters for these functions have required values that
-    are defined in the <<features-features-multiViewport,multiple
-    viewports>> section of the spec but were not reflected in the valid
-    usage text for these functions.
-  * Add the +<<VK_EXT_swapchain_colorspace>>+ extension defining common
-    color spaces.
-
------------------------------------------------------
-
-Change log for December 16, 2016 Vulkan 1.0.38 spec update:
-
-  * Bump API patch number and header version number to 38 for this update.
-
-Github Issues:
-
-  * Make ename:VK_PIPELINE_STAGE_HOST_BIT invalid for all stage masks,
-    except for flink:vkCmdWaitEvents (public issue 261).
-
-Internal Issues:
-
-  * Added validation language for flink:vkQueueBindSparse,
-    slink:VkPresentInfoKHR, and slink:VkSubmitInfo, and a note to the
-    <<synchronization-semaphores-waiting,Semaphore Waiting and Unsignaling>>
-    section to clarify that semaphores must be signaled and waited on in a
-    1:1 fashion (internal issue 546).
-  * Modify valid usage for slink:VkBufferImageCopy to only require
-    pname:bufferOffset to be a multiple of the image format's element size
-    when the format is not depth/stencil (internal issue 594).
-
-Other Issues:
-
-  * Vulkan is now a registered trademark symbol, and this is reflected in
-    documents and copyright statements.
-
------------------------------------------------------
-
-Change log for December 10, 2016 Vulkan 1.0.37 spec update:
-
-  * Bump API patch number and header version number to 37 for this update.
-
-Github Issues:
-
-  * Add usability guarantees on the values returned by
-    flink:vkGetPhysicalDeviceSurfaceCapabilitiesKHR in the
-    slink:VkSurfaceCapabilitiesKHR structure and by
-    flink:vkGetPhysicalDeviceSurfaceFormatsKHR in the
-    pname:pSurfaceFormatCount parameter (public issue 385).
-  * Add elink:VkDebugReportObjectTypeEXT enumerants for new object types
-    introduced by new extensions (public issue 408).
-  * Add +VK_NVX_device_generated_commands+ etext:ACCESS bits and define how
-    they are used (public issue 415).
-  * Fix indentation for slink:VkDebugReportCallbackCreateInfoEXT member
-    descriptions (public issue 419).
-
-Internal Issues:
-
-  * Expand requirements memory binding of non-sparse images and buffers from
-    the <<resources-association,Resource Memory Association>> section into
-    valid usage statements for all of the applicable API calls (internal
-    issue 508).
-  * Explicitly state that valid usage of flink:vkCreateImage requires that
-    flink:vkGetPhysicalDeviceImageFormatProperties would return
-    ename:VK_SUCCESS for the requested image configuration (internal issue
-    598).
-
------------------------------------------------------
-
-Change log for December 1, 2016 Vulkan 1.0.36 spec update:
-
-  * Bump API patch number and header version number to 36 for this update.
-
-Github Issues:
-
-  * Fix "recorded with" terminology in the valid usage language for the
-    flink:vkCmdExecuteCommands::pname:pCommandBuffers parameter (public
-    issue 390).
-  * Modify +genvk.py+ to support specifying extensions to remove from output
-    generators, allowing the extension loader +vulkan_ext.c+ to be created
-    without WSI extensions which are statically exported by the Vulkan
-    loader (public issue 412).
-  * Added validation language for slink:VkSubpassDependency and in the
-    <<synchronization-access-types-supported,supported access types>>
-    section to catch access masks that include bits which are not supported
-    by pipeline stages in the stage masks (partially addresses
-    github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers/issues/1006 ).
-
-Internal Issues:
-
-  * Added validation language for flink:vkCmdWaitEvents,
-    flink:vkQueueSubmit, flink:VkRenderPassCreateInfo, and in the
-    <<synchronization-pipeline-stages-supported>> section to prevent
-    recording stage dependencies that aren't supported on the queue
-    (internal issue 516).
-  * Make a few changes that generalize spec language for use with possible
-    future extensions by adding glossary terms and generalizing ``feature''
-    to ``feature or extension'' where relevant (internal issues 448, 590).
-  * Added "pipeline type" attribute to +vk.xml+ for relevant commands and
-    utilize it in automatic generation of the Command Properties table
-    (internal issue 517).
-  * Specify that WSI implementations must provide both UNORM and sRGB
-    formats in the description of slink:VkColorSpaceKHR (internal issue
-    529).
-  * Remove nesting of explicit valid usage statements where it is not
-    meaningful (internal issue 583).
-
-Other Issues:
-
-  * Add validity language requiring that
-    slink:VkPushConstantRange::pname:offset be a multiple of 4, as stated in
-    the spec language.
-
------------------------------------------------------
-
-Change log for November 25, 2016 Vulkan 1.0.35 spec update:
-
-  * Bump API patch number and header version number to 35 for this update.
-
-Github Issues:
-
-  * Document in the <<memory-device-hostaccess,Host Access>> section that
-    mapping and unmapping does not invalidate or flush the mapped memory
-    (public issues 27, 126).
-  * Redefine the entire <<synchronization>> chapter in terms of consistent
-    and well defined terminology, that's called out at the start of the
-    chapter. This terminology is applied equally to all synchronization
-    types, including subpass dependencies, submissions, and much of the
-    implicit ordering stuff dotted around the spec. Key terms are laid out
-    in the <<synchronization-dependencies,Execution and Memory
-    Dependencies>> section at the top of the rewritten chapter (public
-    issues 128, 131, 132, 217, 299, 300, 302, 306, 322, 346, 347, 371, 407).
-  * Specify order of submission for batches in the
-    <<vkQueueSubmit,vkQueueSubmit>> and
-    <<vkQueueBindSparse,vkQueueBindSparse>> commands (public issue 371).
-  * Add valid usage statements to each of the WSI extension sections
-    indicating that the WSI-specific structure parameters must be valid, and
-    remove automatically generated valid usage statements now covered by the
-    manual sections (public issue 383).
-  * Clarify render pass compatibility for flink:vkCmdExecuteCommands (public
-    issue 390).
-
-Internal Issues:
-
-  * Update +vk.xml+ to make previously explicit valid usage statements for
-    <<vkDebugReportMessageEXT,vkDebugReportMessageEXT>> implicit instead
-    (internal issue 553).
-  * Add valid usage statement for slink:VkCreateImageInfo preventing
-    creation of 1D sparse images (internal issue 573).
-  * Fix Python scripts to always read/write files in utf-8 encoding, and a
-    logic error in reflib.py which could cause a fatal error for
-    malstructured asciidoc (internal issues 578, 586).
-

-
-Change log for November 18, 2016 Vulkan 1.0.34 spec update:
-
-  * Bump API patch number and header version number to 34 for this update.
-
-Github Issues:
-
-  * Allow vkUpdateDescriptorSets overflow to skip empty bindings. Clarify
-    that unused bindings have a descriptorCount of zero. Improve some valid
-    usage for vkUpdateDescriptorSets (public issue 256).
-  * Require that slink:VkImageSubresourceRange always define a non-empty
-    range of the resource (public issue 303).
-  * Added valid usage for slink:VkPresentInfoKHR on the layout of presented
-    images (public issue 397).
-
-Internal Issues:
-
-  * Add dependency in src/spec/Makefile so specversion.txt is regenerated
-    when needed (internal issue 462).
-  * Shorten the table of contents in the single-page ref page HTML output.
-    Still working on the PDF (internal issue 536).
-
------------------------------------------------------
-
-Change log for November 11, 2016 Vulkan 1.0.33 spec update:
-
-  * Bump API patch number and header version number to 33 for this update.
-
-Github Issues:
-
-  * Added implicit external synchronization parameters to
-    vkBegin/EndCommandBuffer, and fixed missing command pool host
-    synchronization from per-command lists (public issue 398).
-  * Started using git tags including the spec release number, such as
-    'v1.0.32-core', instead of tags including the date of release, such as
-    'v1.0-core-20161025' (public issue 405).
-
-Internal Issues:
-
-  * Add validity constraint for
-    slink:VkImportMemoryWin32HandleInfoNV::pname:handle (internal issue
-    #480).
-  * Add scripts to compare two Vulkan HTML specifications, derived from W3
-    htmldiff service (internal issue 525).
-  * Relax requirement that memoryTypeBits can't depend on format, to allow
-    it to differ only for depth/stencil formats (internal issue 544).
-  * Add a new generator script to create a simple extension loader for
-    Vulkan based on +vk.xml+ (internal issue 558).
-  * Add the overlooked requirement that buffer and image memory
-    alignment requirements must be a power of two in the
-    <<resources-association,Resource Memory Association>> section
-    (internal issue 569).
-
-Other Issues:
-
-  * Add a naming rule to the style guide for members of extension structures
-    defining array lengths which are the same as array lengths of the core
-    structure they are chained from.
-  * Add a new generator to create a simple extension loader in
-    +src/ext_loader/vulkan_ext.[ch]+ from +vk.xml+. This code can be
-    included in your project, and is expected to be packaged in the Vulkan
-    SDK provided by LunarG in the future.

-
-Change log for October 25, 2016 Vulkan 1.0.32 spec update:
-
-  * Bump API patch number and header version number to 32 for this update.
-
-Github Issues:
-
-  * Add automatic visibility operations to the presentation engineE when
-    doing a queue present in flink:vkAcquireNextImageKHR. Removed all
-    references to MEMORY_READ that referenced WSI - they no longer make
-    sense (some aspects of public issues 128, 131, 132, 261, and 298).
-  * Document valid non-boolean +externsync+ attribute values for <param>
-    tags in +vk.xml+ (public issue 265).
-  * Add valid usage to slink:VkImageCreateInfo requiring that
-    pname:arrayLayers be 1 for images of type ename:VK_IMAGE_TYPE_3D
-    (public issue 319).
-  * Add missing captions to figures in the <<textures,Image Operations>>
-    chapter (public issue 334).
-  * Clarify WSI interaction with exclusive sharing mode (public issue
-    344).
-  * Added explicit language clarifying the allowed queue usage of
-    resources created with ename:VK_SHARING_MODE_CONCURRENT (public
-    issue 386).
-  * Require that the
-    slink:VkDescriptorSetLayoutCreateInfo::pname:binding members of the
-    pname:pBindings array passed to
-    flink:vkDescriptorSetLayoutCreateInfo all be distinct (public issue
-    391).
-
-Internal Issues:
-
-  * Remove empty validity blocks from +vk.xml+ and suppressed broken
-    validity statements and added missing statements to explicit
-    validity. Doesn't affect output, other than some statements
-    appearing in another block now (internal issue 513).

-Change log for October 14, 2016 Vulkan 1.0.31 spec update:
-
-  * Bump API patch number and header version number to 31 for this update.
-
-Github Issues:
-
-  * Clarifying wording of slink:VkGraphicsPipelineCreateInfo parameters and
-    adding Valid Usage statements on render pass compatibility to the
-    <<drawing,drawing commands>> (public issue 375).
-  * Replace 'texel size' with 'element size', and add a definition to the
-    glossary (public issue 382).
-  * Clarify the description of ename:VK_ERROR_NATIVE_WINDOW_IN_USE_KHR to
-    make it accurate, but still generic (non-exhaustive). Remove two Valid
-    Usage statements describing error situations that will return
-    ename:VK_ERROR_NATIVE_WINDOW_IN_USE_KHR (public issue 387).
-  * Fix refBegin tag for elink:VkDebugReportFlagBitsEXT (public issue 392).
-  * The <<interfaces-builtin-variables,built-in variable>> code:PrimitiveId
-    in a fragment shader needs the code:Input storage class (public issue
-    393).
-
-Internal Issues:
-
-  * Unused ({y,z} and {height,depth} for 1D, z and depth for 2D) offsets
-    must be 0 and unused extents must be 1. Added basic offset and extent
-    valid usage for slink:VkImageResolve to match that of slink:VkImageCopy
-    (internal issue 413).
-  * Describe what flink:vkGetPhysicalDeviceImageFormatProperties returns for
-    pname:sampleCounts when for pname:usage only includes transfer-related
-    flags (internal issue 478).
-  * Remove mention of
-    slink:VkPhysicalDeviceLimits::pname:maxImageArrayLayers from the valid
-    usage for slink:VkImageCreateInfo::pname:arrayLayers (internal issue
-    520).
-  * Tag usages of ``dynamically uniform'' as glossary terms and add a
-    glossary entry pointing to the SPIR-V Specification's definition of the
-    term (internal issue 531).
-

-
-Change log for October 7, 2016 Vulkan 1.0.30 spec update:
-
-  * Bump API patch number and header version number to 30 for this update.
-
-Github Issues:
-
-  * Document missing pname:sType and pname:pNext parameters for
-    slink:VkCommandBufferInheritanceInfo (public issue 224).
-  * As promised, we are removing the example code, from the appendix, for
-    the VK_KHR_surface and VK_KHR_swapchain extensions. The cube demo
-    (shipped in the official Khronos SDK) has been updated, and is the
-    example code that we want people to look at for how to use these two
-    extensions (public issues 279, 308, and 311).
-  * Clarify the formats for which the slink:VkClearColorValue pname:float32
-    member is used. Also clean up related language for flink:vkCmdBlitImage
-    (public issue 369).
-  * Reword the <<invariance, Invariance>> appendix chapter to better match
-    Vulkan terminology (public issue 372).
-
-Internal Issues:
-
-  * Update slink:VkMemoryRequirements to not require a host_visible memory
-    type exists that can be bound to sparse buffers (internal issue 494).
-  * Modify the <<features-supported-sample-counts,Supported Sample Counts>>
-    language to allow multisampled depth-stencil images (internal issue
-    521).
-
------------------------------------------------------
-
-Change log for September 30, 2016 Vulkan 1.0.29 spec update:
-
-  * Bump API patch number and header version number to 29 for this update.
-
-Github Issues:
-
-  * Remove redundant constraint on
-    slink:VkCommandBufferInheritanceInfo::pname:queryFlags (public issue
-    224).
-  * Fix typo and remove link in Note in the
-    <<extended-functionality-instance-extensions-and-devices, Instance
-    Extensions and Device Extensions>> section (public issue 359).
-  * Fix erroneous validation statement for the pname:layout member of
-    slink:VkComputePipelineCreateInfo (public issue 362).
-
-Internal Issues:
-
-  * Restore long figure captions using asciidoc sidebar blocks, due to
-    restrictions of asciidoc syntax (internal issue 101).
-  * Replace most latexmath equations with comparable markup in straight
-    asciidoc, which significantly improves time required to fully load and
-    process the HTML forms of the Specification. There are known minor font
-    and alignment inconsistencies with MathJax and PDF rendering of
-    latexmath equations. Please do not file github issues about these. We
-    are aware of the inconsistencies and will make refinements over time,
-    while the performance improvements are compelling in at least some major
-    browsers (internal issue 313).
-  * Move handcoded validity statements from +vk.xml+ into the Specification
-    body, easing work in the single-branch model. Specify the distinction
-    between these explicit statements, and the implicit validity statements
-    inferred from vk.xml. Validity statements now appear in two blocks for
-    each command and structure - handcoded "Valid Usage" and the implicit
-    "Valid Usage (Implicit)" (internal issue 392).
-  * Add the +returnedonly="false"+ attribute to WSI output structures,
-    removing incorrectly generated implicit validity statements for
-    slink:VkDisplayPropertiesKHR, slink:VkDisplayPlanePropertiesKHR,
-    slink:VkDisplayModePropertiesKHR, slink:VkDisplayPlaneCapabilitiesKHR,
-    slink:VkSurfaceCapabilitiesKHR, and slink:VkSurfaceFormatKHR structures
-    (internal issue 486).
-  * Update slink:VkImageLayout to require the
-    ename:VK_IMAGE_USAGE_SAMPLED_BIT be set for sampled depth/stencil images
-    (internal issue 487).
-  * Use an explicit format specifier string for the date command invocation
-    in the +Makefile+ instead of the shorthand -R option, which doesn't work
-    on BSD and MaxOS X date commands (internal issue 500).
-
-Other Issues:
-
-  * Use the terms ``allocation scope'' and ``extension scope'' instead of
-    just ``scope'', and add them to the glossary.
-
------------------------------------------------------
-
-Change log for September 23, 2016 Vulkan 1.0.28 spec update:
-
-  * Bump API patch number and header version number to 28 for this update.
-
-Github Issues:
-
-  * Minor spelling and typography cleanup, add definitions of
-    ename:VK_FALSE and ename:VK_TRUE as just what their names say
-    (public issues 220, 318, 325, 365; internal issues 451, 496)
-  * Clarify that the pname:maxDescriptorSet limits in the
-    <<features-limits-required,Required Limits>> table are n *
-    maxPerStage limit (where n=number of supported stages) (public issue
-    254).
-  * Minor cleanup to <<boilerplate-platform-macros,Platform-Specific
-    Macro Definitions>> appendix (public issue 314).
-  * Add valid usage statement to slink:VkPipelineLayoutCreateInfo
-    disallowing multiple push constant ranges for the same shader stage
-    (public issue 340).
-  * Clarify the elink:VkSharingMode description of what executing the
-    "same" barriers means in case of ownership transfer (public issue
-    347).
-  * Rename copyright.txt and add COPYING.md to try and reduce confusion
-    about applicable copyrights (public issue 350).
-  * Extend the table in the <<boilerplate-wsi-header, Window System-Specific
-    Header Control>> section to describe the external headers included when
-    each etext:VK_USE_PLATFORM_* macro is defined (public issue 376).
-
-Internal Issues:
-
-  * Add "Revision History" to the PDF outputs following the table of
-    contents, to match HTML outputs (internal issue 43).
-  * Clarified that flink:vkMapMemory may fail due to virtual address
-    space limitations (internal issue 346).
-  * Add +refBody+ comment markup for ref page autoextraction when required
-    (internal issue 400).
-  * Document proper use of "mipmap" and "mip" in the style guide API
-    naming rules, matching the spelling rules (internal issue 471).
-  * Tweak the <<extensions,Layers and Extensions>> appendix to note that
-    the Specification may be built with arbitrary combinations of
-    extensions (internal issue 483).
-  * Remove incorrect statement allowing
-    slink:VkClearAttachment::pname:colorAttachment to be >=
-    slink:VkSubpassDescription::pname:colorAttachmentCount (internal
-    issue 488).
-  * The <<features-limits-viewportboundsrange,viewportBoundsRange>> is
-    expressed in terms of the pname:maxViewportDimensions but this is
-    actually two values. Clarify that it's based on the larger of the two
-    (if they differ) (internal issue 499).
-
-Other Issues:
-
-  * Reflowed text of the entire spec using the 'reflow' Makefile target, to
-    (hopefully) reduce future internal git churn as edits are made and
-    extensions added in return for one-time pain. This has no perceptible
-    effect on the spec outputs, but considerable changes on the asciidoc
-    source (internal issue 367).
-
------------------------------------------------------
-
-Change log for September 16, 2016 Vulkan 1.0.27 spec update:
-
-  * Bump API patch number and header version number to 27 for this update.
-
-Github Issues:
-
-  * Weaken flink:vkGetPipelineCacheData invariance conditions; previous
-    conditions were stronger than agreed and can't be guaranteed (public
-    issue 280).
-  * Add link to "Vulkan Loader Specification and Architecture Overview"
-    document to Normative References section (public issue 359).
-
-Internal Issues:
-
-  * Be more clear in the <<interfaces-resources-layout-std140, uniform
-    buffer layout>> section that block offsets can be out of order
-    (internal issue 396).
-  * Document that extension authors should add support for their extensions
-    to the validation layers (internal issue 398).
-  * Clarify that the valid range of depth clear values should be limited
-    to the 0..1 range and that copies to depth aspect must also be in this
-    range (internal issue 412).
-  * Specify ``a'' vs. ``an'' use in the style guide (internal issue 432).
-  * Increase the maximum pname:nonCoherentAtomSize value in the
-    <<features-limits-required,Required Limits>> section from 128 to 256
-    (internal issue 435).
-  * Fix vk_platform.h for compiler errors on some Android platforms
-    (internal issue 441).
-  * Clarify that slink:VkPhysicalDeviceFeatures::pname:pEnabledFeatures ==
-    `NULL` disables all features, including the "required" feature
-    pname:robustBufferAccess (internal issue 479).
-
-Other Issues:
-
-  * Expand style guide and make it more self-consistent.
-  * Use ISO 8601 date format everywhere.
-  * Emphasise the correct way of using
-    slink:VkSurfaceCapabilitiesKHR::pname:maxImageCount.
-  * Added +VK_EXT_validation_flags+ extension for validation flag mechanism.
-  * Fix an <<credits,author credit>> to include their current employer.
-
------------------------------------------------------
-
-Change log for September 6, 2016 Vulkan 1.0.26 spec update:
-
-  * Bump API patch number and header version number to 26 for this update.
-
-Github Issues:
-
-  * Bring sample code in the `VK_KHR_surface` and `VK_KHR_swapchain`
-    extension summary appendices up to date, and note they will be replaced
-    with pointers to the LunarG SDK examples in the future (public issue
-    279).
-  * Add a new <<fundamentals-commandsyntax-results-lifetime,Lifetime of
-    Retrieved Results>> section specifying that ftext:vkGet* and
-    ftext:VkEnumerate* results are invariant unless otherwise specified, and
-    specify behavior for individual commands which are not invariant (public
-    issue 280).
-  * Remove conflicting definition of
-    slink:VkDisplayPlaneCapabilitiesKHR::pname:maxSrcPosition and clean up
-    language of the remaining definition (public issue 351).
-  * Fix many minor spelling errors and add rules to the style guide to
-    prevent recurrences (public issue 352).
-
-Internal Issues:
-
-  * Remove redundant descriptions of the etext:VK_USE_PLATFORM_* macros from
-    the <<wsi,Window System Integration>> chapter in favor of the
-    description in the <<boilerplate-wsi-header,Window System-Specific
-    Header Control>> appendix (internal issue 6).
-  * Replace misleading 'can: be destroyed when not X' with more correct
-    'must: not be destroyed while X' in the
-    <<fundamentals-objectmodel-lifetime,Object Lifetime>> section. Disallow
-    destroying a pipeline layout while a command buffer using it is
-    recording (internal issue 241).
-  * Clarify that ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT is valid for
-    all images used as attachments in elink:VkImageUsageFlagBits and the
-    slink:VkImageLayout validity language (internal issue 320).
-  * Note that <<extended-functionality-layers,Layers>> may wrap object
-    handles, but that this is a generally discouraged. A link to additional
-    information in the documentation for layer authors is provided (issue
-    398)
-  * Replace the mustnot: and shouldnot: macros with equivalent must: not and
-    should: not to get rid of non-English words while still highlighting
-    normative language (internal issue 407).
-  * Disallow creating multisampled images with
-    ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT in the slink:VkImageLayout
-    validity language and the <<features-supported-sample-counts,Supported
-    Sample Counts>> section (internal issue 445).
-  * Fix typo so that flink:vkCmdDrawIndexedIndirect is defined in terms of
-    flink:vkCmdDrawIndexed rather than flink:vkCmdDrawIndirect (internal
-    issue 446).
-  * Reorganize the per-extension information sections to all be in the
-    <<extensions,Layers & Extensions>> appendix. Also fix a typo in
-    +VK_IMG_filter_cubic+ which incorrectly identified it as a +KHR+
-    extension (internal issue 461).
-
-Other Issues:
-
-  * Use asciidoc markup instead of latexmath to simplify diagrams in the
-    <<features-formats-non-packed,byte mapping tables>> for color formats.
-  * Fix a markup problem with the wildcarded enumerant names in a NOTE in
-    the <<textures-texel-replacement,Texel Replacement>> section.
-  * Fix missing attributes in the XML interface for
-    elink:VkExternalMemoryHandleTypeFlagBitsNV and
-    elink:VkExternalMemoryFeatureFlagBitsNV (KhronosGroup/Vulkan-Hpp issue
-    25)
-  * Cleanup reference page builds so only core pages are built for releases.
-
------------------------------------------------------
-
-Change log for August 26, 2016 Vulkan 1.0.25 spec update:
-
-  * Bump API patch number and header version number to 25 for this update.
-  * Structurally change the specification so that multiple extensions are
-    included in the +1.0+ git branch, and specifications will include or not
-    include those extensions at build time based on options passed to the
-    Makefile. See +doc/specs/vulkan/README.html+ and the ``Layers and
-    Extensions'' section of the ``Vulkan Documentation and Extensions''
-    document for more information on this change.
-  * Register and publish new extensions in the single-branch form:
-  ** +VK_NV_external_memory_capabilities+
-  ** +VK_NV_external_memory+
-  ** +VK_NV_external_memory_win32+
-  ** +VK_NV_win32_keyed_mutex+
-
-Github Issues:
-
-  * Clarify description of GetInstanceProcAddr and GetDeviceProcAddr (public
-    issue 212).
-  * Add SPIR-V <<textures-operation-validation, instruction validation>> for
-    single-sampled images (public issue 316).
-  * Fix spelling of ``tesselation'' in a few places and note it as an
-    exception to the American spelling rules convention (public issue
-    327).
-  * Fix Makefile to create output directory for ``styleguide''
-    target (public issue 329).
-  * Fix numerous minor issues with incorrectly tags on enumerant names and
-    table titles (public issue 330).
-  * Generate specversion.txt date in UTC time and RFC 2822 format
-    (public issue 335).
-  * Convert link to the SPIR-V Specification for
-    flink:VkShaderModuleCreateInfo into an internal link to the normative
-    reference (public issue 336).
-  * Add ename:VK_ERROR_OUT_OF_MEMORY error code to
-    flink:vkCreateDebugReportCallbackEXT (public issue 337).
-
-Internal Issues:
-
-  * Update style guide regarding use of code:NULL and dname:VK_NULL_HANDLE
-    (internal issue 393).
-  * Change the definition of latexmath:[$q$] in the
-    <<textures-image-level-selection,texture image level selection>> section
-    to be the index of the maximum defined level for the view, not the
-    number of levels in the view (internal issue 406).
-  * Allow developers to override dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE
-    with their own binary-compatible definition (internal issue 439).
-  * Fix +vk_platform.h+ conditional logic causing compile failure with some
-    Android compilers (internal issue 441).
-  * Implement the single-branch model as described above (internal issue

-
-Change log for August 12, 2016 Vulkan 1.0.24 spec update:
-
-  * Bump API patch number and header version number to 24 for this update.
-
-Github Issues:
-
-  * Fix type mismatch in swapchain image equivalency table (public issue
-    289).
-  * Fix a copy-and-paste error in the description of
-    flink:vkGetSwapchainImagesKHR::pname:pSwapchainImages, that said it
-    was an array of ``sname:VkSwapchainImageKHR structures'' instead of
-    an array of ``sname:VkImage handles'' (public issue 292).
-  * Specify that ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT is only valid
-    for ename:VK_IMAGE_TYPE_2D images (public issue 293).
-  * Add a valid usage statement to flink:vkCmdExecuteCommands saying
-    that when called outside a render pass instance, the secondary
-    command buffers must not have been created with the
-    ename:VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT (public issue
-    297).
-  * Fix description of +VK_NO_STDINT_H+ in the
-    <<boilerplate-platform-macros,platform macros>> section (public
-    issue 314).
-
-Internal Issues:
-
-  * Normalize the language for the remaining built-in variables in the
-    <<interfaces-builtin-variables,Built-In Variables>> section. Fix
-    code:FrontFacing and code:HelperInvocation, as they should be of
-    code:boolean type rather than code:integer (internal issue 323).
-  * Clarify that when ename:VK_WHOLE_SIZE is used for a buffer
-    descriptor range, the effective range must still be within the max
-    buffer range (internal issue 426).
-  * Clarify that command buffers and descriptor sets are allocated
-    rather than created. Also clarify when the recording state of a
-    command buffer is relevant (internal issue 434).
-
------------------------------------------------------
-
-Change log for August 5, 2016 Vulkan 1.0.23 spec update:
-
-  * Bump API patch number and header version number to 23 for this update.
-
-Github Issues:
-
-  * Add explicit valid value attributes to pname:sType members in vk.xml
-    (public issue 34).
-  * Clarify usage of flink:vkGetInstanceProcAddr and
-    flink:vkGetDeviceProcAddr (public issue 225).
-  * Fix a copy-and-paste error in the description of
-    pname:pSwapchainImageCount saying that it was the count of ``format
-    pairs'' instead of ``swapchain images'' (public issue 292).
-  * flink:vkCmdExecuteCommandBuffers requires all command buffers to be
-    allocated from command pools created for the same queue family (public
-    issue 296).
-  * Remove bogus +optional+ attribute for
-    flink:vkEnumerateDeviceLayerProperties::pname:physicalDevice from vk.xml
-    (public issue 301).
-  * Clean up the <<resources-image-views-compatibility,image and image view
-    compatibility table>> reference and contents. Use full enumerant names.
-    Refer to pname:layerCount in the ``view parameters'' column instead of
-    pname:arrayLayers. Require N >= 1 for the cube array subview row, not
-    just arrayLayers >= 6 N (public issue 304).
-  * Modify description of <<resources-memory-aliasing,memory aliasing>> to
-    be consistent with the description of
-    <<resources-bufferimagegranularity,buffer image granularity>> (public
-    issue 307).
-
-Internal Issues:
-
-  * Describe remaining +vk_platform.h+ macros in the <<boilerplate,API
-    Boilerplate>> appendix (internal issue 6).
-  * Clarify
-    <<features-features-robustBufferAccess,pname:robustBufferAccess>>
-    feature behavior; what memory can be accessed, how bounds checking is
-    performed, and allowing for vectorization (internal issue 332).
-  * Document markup for automatic extraction of reference pages from the
-    spec sources in the style guide (internal issue 395).
-  * Allow flink:vkCreateDisplayModeKHR to return
-    ename:VK_ERROR_INITIALIZAION_FAILED_KHR if the user requests mode
-    parameters that the specified display does not support (internal issue
-    411).
-  * Remove atomic counters (atomic_uint style) from KHR_vulkan_glsl, and
-    more clearly remove the subroutine keyword alongside it (internal issue
-    421).
-  * Clarify behavior of flink:vkCmdBindDescriptorSets for descriptor sets
-    not contained in the layout (internal issue 427).
-
-Other Commits:
-
-  * Change the order in which members of sname:VkAttachmentDescription and

------------------------------------------------------
-
-Change log for July 22, 2016 Vulkan 1.0.22 spec update:
-
-  * Bump API patch number and header version number to 22 for this update.
-
-Github Issues:
-
-  * Translate the subpass self-dependency language into concrete
-    validity statements, and added a validity statement about the
-    restrictions on layout parameters (public issue 267).
-  * Add validity requirement that
-    slink:VkAttachmentDescription::pname:finalLayout and
-    slink:VkAttachmentReference::pname:layout must not be
-    ename:VK_IMAGE_LAYOUT_UNDEFINED or
-    ename:VK_IMAGE_LAYOUT_PREINITIALIZED (public issue 268).
-  * Clarify that slink:VkSubpassDescription::pname:pResolveAttachments
-    layouts are used. Make language consistent with other attachment
-    arrays (public issue 270).
-  * Changed 64-bit definition for
-    dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE to work for x32 platform in
-    +vk.xml+ and the resulting +vulkan.h+ (public issue 282).
-  * Add missing error return code for
-    flink:vkEnumerateInstanceExtensionProperties and
-    flink:vkEnumerateDeviceExtensionProperties (public issue 285)
-  * Fix several cases of stext::VkStructName.memberName markup to
-    stext::VkStructName::pname:memberName, to match other usage in the
-    spec, and describe this markup in the style guide (public issue
-    286).
-  * Modified validity language generation script to avoid redundant
-    common ancestor language if covered by generic parent language, and
-    used `Both' instead of `Each' when appropriate (public issue 288).
-
-Internal Issues:
-
-  * Add language about behavior of flink:vkAllocateDescriptorSets when
-    allocation fails due to fragmentation, a new error
-    ename:VK_ERROR_FRAGMENTED_POOL, and a Note explaining the situation
-    (internal issue 309).
-  * For the features of code:PointSize, code:ClipDistance, and
-    code:CullDistance, the SPIR-V capability is required to be declared
-    on use (read or write) rather than on decoration (internal issue
-    359).
-  * Have desktop versions of GLSL respect precision qualification
-    (code:mediump and code:lowp) when compiling for Vulkan. These will
-    get translated to SPIR-V's code:RelaxedPrecision decoration as they
-    do with OpenGL ES versions of GLSL (ESSL). The default precision of
-    all types is code:highp when using a desktop version (internal issue
-    360).
-  * Add validity statement for slink:VkImageCreateInfo specifying that
-    multisampled images must be two-dimensional, optimally tiled, and
-    with a single mipmap level (internal issue 369).
-  * Add validity statements to slink:VkImageViewCreateInfo disallowing
-    creation of images or image views with no supported features. Made
-    some slink:VkImageViewCreateInfo validity statements more precise
-    and consistent. Added a Note to the <<features,features>> chapter
-    about formats with no features (internal issue 371).
-  * Remove +manpages+ from default build targets. Nroff outputs
-    containing imbedded latexmath will not render properly. Fixing this
-    is a lot of work for limited use cases (internal issue 401).
-
-Other Commits:
-
-  * Fix flink:vkRenderPassBeginInfo::pname:clearValueCount validity
-    statement to be based on attachment indices rather than the number
-    of cleared attachments
-    (Vulkan-LoaderAndValidationLayers/issues/601).
-  * Convert registry documentation from LaTeX to asciidoc source and
-    rename from +src/spec/readme.tex+ to +src/spec/registry.txt+.
-  * Fix lack of Oxford commas in validity language.
-  * Lots of cleanup of generator scripts and Makefiles to move extension
-    list for generator into the script arguments instead of the body of
-    genvk.py, and express better dependencies between XML, scripts, and
-    generated files.

-Change log for July 15, 2016 Vulkan 1.0.21 spec update:
-
-  * Bump API patch number and header version number to 21 for this update.
-
-Github Issues:
-
-  * Clarify how <<features-supported-sample-counts,sample count queries>>
-    relate to the limits in slink:VkPhysicalDeviceLimits. (public issue
-    185).
-  * Clarify in the <<interfaces-iointerfaces,Shader Input and Output
-    Interfaces>> section that shader output variables have undefined values
-    until the shader writes to them (public issue 240).
-  * Specify the implicit value of image parameters that cannot be set in
-    slink:VkSwapchainCreateInfo::pname:flags, pname:imageType,
-    pname:mipLevels, pname:samples, pname:tiling, and pname:initialLayout
-    (public issue 243).
-  * Make use of code:NULL and code:VK_NULL_HANDLE consistent in the
-    VK_KHR_swapchain extension (public issue 276).
-
-Internal Issues:
-
-  * Clarify that presenting an image to a display surface swapchain applies
-    the display surface's mode, and that destroying a display surface
-    swapchain may reset the display's mode, in the VK_KHR_display_swapchain
-    extension (internal issue 247).
-  * Better describe what a slink:VkSurfaceKHR is, and that creating one does
-    not set a mode, in the VK_KHR_display extension. This is a round-about
-    way of pointing out that mode setting is not covered by the extension,
-    but rather is performed as a side effect of presentation (internal issue
-    247).
-  * Add more valid usage statements to flink:vkQueuePresentKHR command when
-    the VK_KHR_display_swapchain extension is present (internal issue
-    247).
-  * Add more includes to the VK_KHR_swapchain extension to better document
-    interactions with VK_KHR_display_swapchain (internal issue 247).
-  * Clarify restrictions on location aliasing in the
-    <<fxvertex,Fixed-Function Vertex Processing>> section (internal issue
-    370).
-  * Add mathematical description of blitting to flink:vkCmdBlitImage, and
-    link it to the <<textures,Image Operations>> chapter. Use mathematical
-    notation for ranges of texel coordinates in the <<textures,Image
-    Operations>> chapter. Fixed miscellaneous validity statements for
-    flink:vkCmdBlit and slink:VkImageBlit (internal issue 382).
-
-Other Commits:
-
-  * Added a valid usage rule to flink:VkGraphicsPipelineCreateInfo that the
-    ename:VK_PRIMITIVE_TOPOLOGY_PATCH_LIST topology must only be used when
-    tessellation shaders are used.
-  * Expand the style guide into a formal "Procedures and Conventions"
-    document. Add a API Naming Conventions section, move most of the API
-    Specification Appendix C (Layers and Extensions) content into the new
-    document, and define the resulting procedures as mandatory (where
-    relevant). This more clearly separates use vs. specification of Vulkan
-    APIs.
-  * Update vk_platform.h to handle 32-bit ARMv8 binaries.
-  * Various minor cleanups to the Makefile and build process.
-
------------------------------------------------------
-
-Change log for July 8, 2016 Vulkan 1.0.20 spec update:
-
-  * Bump API patch number and header version number to 20 for this
-    update.
-
-Github Issues:
-
-  * Replaced existing reference pages by text automatically extracted from
-    the specification source, or generated from vk.xml in some cases. This
-    is not a complete solution for the reference pages, but puts them in a
-    much better state. The ref pages (only) are now placed under a CC BY
-    open source license, which is more current than the obsolete license
-    previously used. Various minor tweaks to the Specification sources were
-    made to enable this, and a new ``API Boilerplate'' chapter added to
-    include definitions of all the entities in the API and +vulkan.h+ which
-    were not already described in some form in the document.
-
-    Further improvements to the pages should not edit them directly, but
-    instead concentrate on the specification source from which the ref pages
-    are being extracted (public issues 44, 55, 160; internal issue 389).
-
------------------------------------------------------
-
-Change log for July 1, 2016 Vulkan 1.0.19 spec update:
-
-  * Bump API patch number and header version number to 19 for this
-    update.
-
-Github Issues:
-
-  * Clarified how flink:vkGetImageSubresourceLayout interacts with image
-    layouts (public issue 247).
-  * Remove ename:VK_IMAGE_LAYOUT_PREINITIALIZED from valid usage rule for
-    slink:VkImageMemoryBarrier::pname:oldLayout. It is only valid if it is
-    the current layout (public issue 248).
-  * Modify valid usage for flink:vkBindBufferMemory so implementations are
-    free to require a different backing memory size than the buffer size
-    (public issue 251).
-  * Clarify that filtering rules for flink:vkCmdBlitImage always apply, and
-    are usually no-ops if the formats are the same (public issue 253).
-  * Remove 'non-sparse' from description of
-    flink:vkGetBufferMemoryRequirements and
-    flink:vkGetImageMemoryRequirements (public issue 257).
-  * Remove ename:VK_ERROR_LAYER_NOT_PRESENT error code from
-    flink:vkCreateDevice (public issue 259).
-  * Change "must: not" to "should: not" in constraint on when
-    flink:vkAcquireNextImageKHR is called in the VK_KHR_swapchain branch
-    (public issue 262).
-  * Change type of flink:vkCmdUpdateBuffer::pname:pData from
-    basetype:uint32_t* to basetype:void* (public issue 263).
-  * Change should: to must: in description of where additional segments are
-    placed in the <<[tessellation-tessellator-spacing,Tessellator Spacing>>
-    section (public issue 264).
-
-Internal Issues:
-
-  * Normalize the language of all the compute shader built-ins in the
-    <<interfaces-builtin-variables,Built-in Variables>> section (internal
-    issue 323).
-  * Remove definition of presentation engine internal queue lengths
-    associated with ename:VK_PRESENT_MODE_FIFO_KHR and
-    ename:VK_PRESENT_MODE_FIFO_RELAXED_KHR in the <<Window System
-    Integration,wsi>> chapter (internal issue 374).
-  * The language of a Note was too broad, and implied that loaders for a
-    given OS would statically export functions for WSI extensions that
-    were not relevant to (or supported on) the OS. Also, removed
-    "Khronos-provided" since the Android loader is not (internal issue 380)
-
-Other Commits:
-
-  * Add ename:VK_INCOMPLETE to list of return values for
-    flink:vkGetPipelineCacheData. Spec says this value is returnable, but it
-    was not listed in the error codes.
-  * Fix "correponds" typo in member definitions for
-    slink:VkSubpassDescription.
-
------------------------------------------------------
-
-Change log for June 24, 2016 Vulkan 1.0.18 spec update:
-
-  * Bump API patch number and header version number to 18 for this
-    update.
-
-Github Issues:
-
-  * Added "queue operation" terminology, and modified spec to actually
-    use this terminology (public issue 155). The act of submitting a
-    piece of work to a queue now generates "operations" for the queue to
-    execute, including operations to wait on/signal semaphores and
-    fences. Synchronization waits on these operations, making execution
-    dependency chains more obvious for semaphores and fences (though
-    additional work is still needed here). These changes include:
-  ** Overview of "queue submission" commands in chapter
-     <<devsandqueues-submission>>.
-  ** Updated descriptions for fence and semaphore waits and signals in
-     the synchronization chapter <<synchronization-semaphores-waiting>>,
-     <<synchronization-semaphores-signaling>> and
-     <<synchronization-fences-waiting>>.
-  ** Clarifications to semaphore and fence operation within queue
-     submission functions.
-  ** New glossary terms.
-  ** Moved device idle and queue wait idle to synchronization chapter in
-     order to describe them in terms of other synchronization
-     primitives.
-  ** Clarifications to semaphore and fence operation allowed removal of
-     the "implicit ordering guarantees" section, as this information is
-     now wholly covered where these primitives are described.
-  *** The "host writes" section of this is still there for now - in its
-      own section. This could probably be merged into other sections
-      later.
-  *** Modified fundamentals chapter on queue ordering to make sense in
-      context of the new changes, and avoid duplication.
-      <<fundamentals-queueoperation>>
-  * Added "aspect" and "component" definitions to the glossary, and made
-    sure these terms are referenced correctly (public issue 163).
-  * Update valid usage for ftext:vkGet*ProcAddr to only include
-    conditions that must be met to get a valid result. In particular,
-    it is okay to call flink:vkGetDeviceProcAddr with any string and will
-    get a code:NULL if that string is not a core Vulkan function or an
-    enabled extension function (addresses but does not fully close
-    public issue 214).
-  * Change the WSI extension dependencies to refer to version 1.0 of the
-    Vulkan API, instead of the pre-1.0-release internal revisions
-    numbers (public issue 238).
-  * Specified that <<interfaces-fragmentoutput,undeclared fragment
-    shader outputs>> result in undefined values input to the blending
-    unit or color attachment (public issue 240).
-  * Fix latexmath:[$\leq$] operators turning into Unicode left arrow symbols
-    (public issue 245).
-
-Internal Issues:
-
-  * Better documented that the registry XML "optional" tag for values
-    only applies when that value is the size of an array (internal issue
-    335).
-  * Add a stronger definition for the valid usages of
-    VkSpecializationMapEntry.size in the
-    <<pipelines-specialization-constants,Specialization Constants>>
-    section (internal issue 345).
-  * Change code:OpName to code:OpDecorate (along with appropriate
-    syntax) for vertex shader built-ins (internal issue 368).
-  * Add missing ref pages (those which are not currently stubs) to
-    apispec.txt for the single-page version of the ref pages (internal
-    issue 378).
-
-Other Commits:
-
-  * Fix example in the <<descriptorsets,Descriptor Sets>> section to use
-    M, N, and I, describing set, binding, and index, consistently
-    throughout the example code.
-
------------------------------------------------------
-
-Change log for June 17, 2016 Vulkan 1.0.17 spec update:
-
-  * Bump API patch number and header version number to 17 for this
-    update.
-
-Github Issues:
-
-  * Update description of vertex shader reuse in
-    <<shaders-vertex-execution>> (public issue 106).
-  * Simplify validity language around pname:ppEnabledExtensionNames and
-    pname:ppEnabledLayerNames (in the <<initialization-instances>> and
-    <<devsandqueues-device-creation>> sections) (public issue 214).
-  * Add missing validity rule to flink:vkCmdBeginRenderPass requiring
-    compatibility between slink:VkAttachmentDescription pname:initalLayout
-    members and the corresponding attached framebuffer images (public issue
-    233).
-  * Fix Unicode arrows appearing in output instead of relational operators
-    (public issue 239).
-  * Correctly describe the required number of elements for
-    code:TessLevelInner and code:TessLevelOuter arrays in the
-    <<interfaces-builtin-variables,Built-In Variables>> section as two and
-    four, respectively, instead of the other way around, and refer to this
-    section from the <<tessellation,Tessellation>> chapter (public issue
-    246).
-
-Internal Issues:
-
-  * Document deprecation of ename:VK_COLORSPACE_SRGB_NONLINEAR_KHR in the
-    VK_KHR_surface extension, and of
-    ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CREATE_INFO_EXT in the
-    VK_EXT_debug_report extension (internal issue 328).
-  * Added language to define what a valid usage statement is and should be,
-    with a note about some apparent weirdnesses this might entail (internal
-    issue 357).
-
-Other Commits:
-
-  * Added missing ename:VK_ERROR_DEVICE_LOST error to
-    flink:vkQueueBindSparse.
-
------------------------------------------------------
-
-Change log for June 10, 2016 Vulkan 1.0.16 spec update:
-
-  * Bump API patch number and header version number to 16 for this
-    update.
-
-Github Issues:
-
-  * Clarify that integer border values are meant to be 0/1, and that
-    integer texture lookups are sign-extended in the
-    <<textures-format-conversion,Format Conversion>> and
-    <<textures-texel-replacement,Texel Replacement>> sections (public
-    issue 52).
-  * Add logic to generate spec boilerplate without using the 'git'
-    command-line client, needed when building from a tarball or another
-    source of the Vulkan tree rather than a cloned git repo. Remove
-    boilerplate as part of 'clean' target (public issue 195).
-  * Document that color writes and clears to unused attachments have no
-    effect for slink:VkClearAttachment and
-    elink:VkColorComponentFlagBits (public issue 198).
-  * Fixed flink:vkCmdExecuteCommands validity statement for
-    sname:VkCommandBufferInheritanceInfo::pname:framebuffer. If used, it
-    must match the framebuffer in the current renderpass instance
-    (public issue 226).
-  * Added valid usage language to require for all functions that set
-    dynamic state that the currently bound graphics pipeline has the
-    corresponding dynamic state enabled (public issue 235).
-
-Internal Issues:
-
-  * Clarify for flink:vkEnumerateInstanceExtensionProperties, in the
-    <<extended-functionality-instance-extensions-and-devices, Instance
-    Extensions and Device Extensions>> section, and in the
-    <<glossary,Glossary>> section when functionality should be exposed
-    as an instance extension, as a device extension, or as both
-    (internal issue 109).
-  * Place WorkgroupSize in alphabetical order in the
-    <<interfaces-builtin-variables,Built-in Variables>> section
-    (internal issue 323).
-  * Corrects valid usage in vkEndRenderPass to only affect primary
-    render passes, as secondaries may be entirely within a render pass,
-    and should be able to be ended (previous language disallowed that)
-    (internal issue 338).
-  * Fix relational operator from <= to >= in the
-    <<features-extentperimagetype,Allowed Extent Values>> section
-    (internal issue 343).
-  * Disallow recursion under SPIR-V entry points in the
-    <<spirvenv-module-validation,Validation Rules within a Module>>
-    section (internal SPIR-V issue 37).
-
-Other Commits:
-
-  * Use standard Python ElementTree package instead of lxml.etree in
-    header / validation layer / include autogeneration from XML,
-    reducing platform dependencies.
-
------------------------------------------------------

-
-  * Fixed the <<glossary,Glossary>> entry for Fragment Input Attachment
-    Interface to specify code:UniformConstant storage class (public issue
-    156).
-  * Disallow lazily allocated memory for buffers in the description of
-    slink:VkMemoryRequirements::pname:memoryTypeBits (public issue 196).
-  * Add numbered figure captions (public issue 219).
-  * Fix output variable names in the <<fundamentals-fpfixedconv,Conversion
-    from Floating-Point to Normalized Fixed-Point>> section and related
-    minor normative language and markup cleanup (public issue 220).
-
-Internal Issues:
-
-  * Fix reference to nonexistent etext:VK_IMAGE_LAYOUT_TRANSFER_{SRC,DST}BIT
-    to the actual etext:VK_IMAGE_LAYOUT{SRC,DST}_OPTIMAL (internal issue
-    296).
-  * Update the <<sparsememory-sparse-memory-aliasing,Sparse Resource
-    Implementation Guidelines>> to refer to the correct feature names
-    (internal issue 305).
-

-
-Github Issues:
-
-  * Fix validity language for sname:VkCommandBufferAllocateInfo to
-    impose range limits on pname:commandBufferCount (public issue 178).
-  * Fix validity language for flink:vkCmdExecuteCommands to refer to the
-    correct structure names (public issue 179).
-  * Fix two copy-and-paste errors in the WSI queries, where the wrong
-    term was used for what was being returned (public issue 206).
-  * Add a note in the documentation of
-    flink:vkGetPhysicalDeviceSurfaceFormatsKHR, about what it means if
-    ename:VK_FORMAT_UNDEFINED is returned (public issue 207).
-
-Internal Issues:
-
-  * Clarify the usage and correct the name for the bitmask referenced in
-    <<queries-pipestats,Pipeline Statistics Queries>> (internal issue
-    334).
-
-Other Commits:
-
-  * Fix the names of decorations listed in the
-    <<interfaces-builtin-variables,Built-in Variables>> section such
-    that they match the SPIR-V specification.

-  * Replaced {apiname} with ``Vulkan'' in XML validity statements (public
-    issue 199).
-  * Fix dead links for WSI handle types (public issue 200).
-  * Use "signaled" instead of "signalled" spelling everywhere (public issue
-    201).
-  * Move readme.pdf target directory for XML schema documentation into the
-    target generation directory, instead of leaving it checked into the spec
-    source tree (public issue 203).
-  * Fix duplicate 'which which' typo in description of
-    elink:VkCommandPoolResetFlagBits (public issue 204).
-  * Move the <<Programmable Primitive Shading>> section up one level, out of
-    the <<drawing-primitive-topologies,Primitive Topologies>> section
-    (public issue 209).
-
-Internal Issues:
-
-  * Clarify in the <<pipelines-cache,Pipeline Cache>> section that
-    implementations should not manage the size of pipeline cache (internal
-    issue 192).
-  * Deprecate the concept of device layers and associated commands (internal
-    issue 255).
-  * Remove ename:VK_INCOMPLETE from the list of possible result codes of
-    flink:vkGetPhysicalDeviceSurfaceCapabilitiesKHR (internal issue 314).
-  * Add missing std140/std430 rule: the base alignment of a member following
-    a structure is a multiple of the structure's base alignment (internal
-    issue 321).
-  * Fixes naming of the single elink:VkColorSpaceKHR enum from
-    ename:VK_COLORSPACE_SRGB_NONLINEAR_KHR to
-    ename:VK_COLOR_SPACE_SRGB_NONLINEAR_KHR in XML/header and the
-    VK_KHR_swapchain and VK_KHR_surface extensions to match the style of the
-    typename (space and color are two words, not one) (internal issue 322).
-  * Make it clear that code:LocalInvocationID should only be applied to an
-    input variable and normalize the language describing
-    code:LocalInvocationID to the language for other compute shader
-    variables in the <<interfaces-builtin-variables,Built-in Variables>>
-    section, and add normative language (internal issue 323).
-  * Clarify in the <<fundamentals-returncodes,Return Codes>> section that
-    the result pointer may be modified for specific commands, even if a
-    runtime error is returned (internal issue 324).

-  * Change valid usage statements intended to be "sub-points" to
-    be actual sub-points (public issue 66).
-  * Replace double negation in description of
-    slink:VkRenderPassBeginInfo::pname:pClearValues (based on public
-    merge 142).
-  * Cleanup minor typos in spec, ref pages and XML, including those
-    proposed in public pull requests 144, 150, 151, 167, 168, 181, and
-    186.
-  * Use *strict subset* in describing the partial order of memory
-    property types for slink:VkMemoryType, and update the style guide
-    accordingly (public issue 190).
-  * Fix various "a image" -> "an image" typos (public issue 191).
-  * Note in the <<fundamentals-validusage,Valid Usage>> and
-    <<extensions-interactions,Extension Interactions>> sections that
-    structures defined by extensions which may be passed in structure
-    chains using the ptext:pNext member must include initial
-    ptext:sType and ptext:pNext members (public issue 192).
-
-Internal Issues:
-
-  * Remove duplicate language from the description of the pname:fence
-    parameter to flink:vkQueueSubmit and improve validity language
-    (internal issue 91).

-    (internal issue 149).
-  * Clarify the host-side data validity rules and behavior of
-    flink:vkFlushMappedMemoryRanges and
-    flink:vkInvalidateMappedMemoryRanges (internal issue 266).
-
-Other Commits:
-
-  * Added clarification to flink:vkCmdFillBuffer regarding the use of

-    ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT flag.
-    Correct all the draw/dispatch commands to mention optimally tiled
-    images as well as linear tiled images, and say image VIEWS instead
-    of images. Add validity statement to flink:vkCmdBlitImage
-  * Replace the {apiname} macro with hardcoded "Vulkan", now that we have
-    committed to that name.
-  * Add the VK_AMD_rasterization_order extension to vk.xml.

-
-Change log for April 22, 2016 Vulkan 1.0.11 spec update:
-
-  * Bump API patch number and header version number to 11 for this
-    update.
-
-Github Issues:
-
-  * Clarify the WSI extension language by switching from the fuzzier
-    "ownership" language to more-consistent "acquire" language (public
-    issue 117).
-  * Clarify that memory barriers apply to all commands in the dependency
-    chains in the flink:vkGetRenderAreaGranularity command and the
-    <<synchronization-execution-and-memory-dependencies,Execution And
-    Memory Dependencies>> section (public issue 132).
-  * Clarify that a queue family is a set of queues in the
-    <<fundamentals-execmodel,Execution Model>> section (public issue
-    166).
-  * Removed requirement from valid usage language that
-    VkPresentInfoKHR::waitSemaphoreCount must be greater than 0 (public
-    issue 171).
-  * Fix broken internal links, describe structures consistently, use
-    consistent style for SPIR-V codewords, and tag normative terms that
-    were missing asciidoc tags (public issue 183 and ancillary
-    markup/normative language fixes).
-  * Fix typos for slink:VkPhysicalDeviceLimits member names in
-    slink:VkImageCreateInfo validity language (public issue 184).
-
-Internal Issues:
-
-  * Document that the requested patch version number specified as part
-    of slink:VkApplicationInfo::pname:apiVersion is ignored when
-    creating an instance (internal issue 176).
-  * Clarify handling of extension structs in the
-    <<fundamentals-validusageValid Usage>> section (internal issue 254).
-  * Update required slink:VkImageFormatProperties::pname:maxMipLevels to
-    be limited to the maximum allowed mipmap pyramid size corresponding
-    to the actual maximum supported size for the format (internal issue
-    256).
-  * Modify the <<features-extentperimagetype,Allowed Extent Values Based
-    On Image Type>> section so the allowed maximum extent is the maximum
-    image dimension supported for each dimension of the type of texture
-    being queried (internal issue 257).
-  * Clarify in the <<spirvenv-module-validation,Validation Rules within
-    a Module>> section that at least one of the code:LocalSize execution
-    mode or code:WorkgroupSize decoration is required for each compute
-    shader entry point in a shader module (internal issue 279).

-    anywhere near that size (internal issue 284).
-
-Other Commits:
-
-  * Fix various minor markup errors reported by validation scripts.
-  * Change copyright from Khronos Free Use License to Apache 2.0 license
-    on relevant script/XML/header files. This does not affect the
-    specification source copyright.

-Change log for April 15, 2016 Vulkan 1.0.10 spec update:
-
-  * Bump API patch number and header version number to 10 for this
-    update.
-
-Github Issues:
-
-  * Slightly tweak the <<memory-allocation,Host Memory>> allocator language
-    so that an application wrapping the standard C alloc/free/realloc
-    functions is still correct - the previous language was too strong with
-    regards to freeing memory. Also made certain scenarios clearer - an
-    implementation may now continue without error if an allocation failed
-    and it is able to continue correctly (public issue 21).
-  * Require that etext:VK_*_CREATE_SPARSE_BINDING_BIT is set when the
-    corresponding etext:VK_*_CREATE_SPARSE_RESIDENCY_BIT is used, in the
-    <<sparsememory-miptail,Mip Tail Regions>> section and related commands
-    flink:vkCreateBuffer and flink:vkCreateImage (public issue 84).
-  * Update the <<features,Features, Limits, and Formats>> chapter to clarify
-    interactions between optional features and dynamic state for the
-    pname:depthBiasClamp and pname:wideLines features (public issue 89).
-  * Describe the code:WorkgroupSize builtin in the
-    <<interfaces-builtin-variables,Built-In Variables>> section, and update
-    the <<compute-shaders,Compute Shaders>> section to further clarify how
-    to set the number of workgroups to execute in a compute shader (public
-    issue 145).
-  * Use the term *image subresource* everywhere instead of *subresource*,
-    except for the special case of *host-accessible subresource*, which may
-    be either an image subresource or buffer range (public issue 120)
-  * Add a note to the <<features,Features, Limits, and Formats>> section
-    about extensibility of structures (Public issue 165).
-  * Fix return code flink:vkAcquireNextImageKHR when the timeout parameter
-    is 0 to ename:VK_NOT_READY instead of ename:VK_TIMEOUT (public issue
-    170).
-  * Fix typo in slink:VkLayerProperties::pname:apiVersion field (public
-    issue 172).
-
-Internal Issues:
-
-  * Fix a few minor internally-detected typos.
-  * Minor formatting tweaks to pseudocode in the <<resources,Resource
-    Creation>> chapter (internal issue 179).
-  * Fix typo in the definition of point sampling for
-    elink:VkCullModeFlagBits (internal issue 268).
-
------------------------------------------------------
-
-Change log for April 8, 2016 Vulkan 1.0.9 spec update:
-
-  * Bump API patch number and header version number to 9 for this
-    update.
-
-Github Issues:
-
-  * Fix memory type preorder definition and clarify example list and source
-    code for slink:VkMemoryRequirements and slink:VkMemoryHeap (public issue
-    26).
-  * Ensure slink:VkAllocationCallbacks are properly defined (public issue
-    73).
-  * Clarify the WSI extension language by switching from the fuzzier
-    "ownership" language to more-consistent "acquire" language (public issue
-    117).
-  * Add language allowing allocation and freeing of memory scoped to the
-    duration of any API command in the <<memory-allocation,Memory
-    Allocation>> section (public issue 136).
-  * Clarify the explicit location assignment always overrides the inherited
-    location in the <<interfaces-iointerfaces-locations,Location
-    Assignment>> section, even for the first member of a block (public issue
-    141).
-  * Fixed references to
-    slink:VkCommandBufferInheritanceInfo::pname:pipelineStatistics (public
-    issue 158).
-  * Fix name of slink:VkBufferCopy::pname:size field in validity language
-    for flink:vkCmdCopyBuffer (public issue 162).
-
-Internal Issues:
-
-  * Update GL_KHR_vulkan_glsl specification to clarify disallowance of
-    spec-const arrays in initializers (internal issue 248).
-  * Clarify <<interfaces-iointerfaces-matching,Interface Matching>> section
-    to state that user-defined variable interface must match too (internal
-    issue 250).
-
------------------------------------------------------
-
-Change log for April 1, 2016 Vulkan 1.0.8 spec update:
-
-  * Bump API patch number and header version number to 8 for this
-    update.
-
-Github Issues:
-
-  * Specify in the validity language for flink:vkBeginCommandBuffer that
-    pname:commandBuffer must not currently be pending execution (public
-    issue 96).
-  * Describe depth comparison using the correct temporary variable names
-    in the <<textures-depth-compare-operation,Depth Compare Operation>>
-    section (public issue 100).
-  * Clarify the order of descriptor update operations in the
-    flink:vkUpdateDescriptorSets command (public issue 115).
-  * Specify in the VK_KHR_swapchain extension that
-    flink:vkAcquireNextImageKHR's pname:semaphore and pname:fence
-    parameters cannot both be sname:VK_NULL_HANDLE (partly addresses,
-    but does not fully close, public issue 117 / internal issue 246).
-  * Change reference to the "lifetime" of a Vulkan command to
-    "duration", and define the "duration" term (public issue 135).
-  * Added valid usage language for slink:VkImageLayout to require both
-    pname:height and pname:depth to be 1 for 1D images and pname:depth
-    to be 1 for 2D images (public issue 137).
-  * Fix SPIR-V example code in the
-    <<descriptorsets-inputattachment,Input Attachment>> section to
-    properly decorate the code:InputAttachmentIndex (public issue 139).
-  * Fix reference to nonexistent pname:imageInfo in the description of
-    flink:VkWriteDescriptorSet to refer to pname:pImageInfo (public
-    issue 140).
-
-Internal Issues:
-
-  * Link to the fixed-function vertex chapter from the drawing chapter
-    (internal issue 110)
-  * Fix typo in slink:VkImageCreateInfo validity language:
-    ptext:maxExtent.sampleCounts -> pname:sampleCounts (internal issue
-    249).
-  * Explain why the non-core token etext:VK_IMAGE_LAYOUT_PRESENT_SRC_KHR
-    is used in the example in the
-    <<synchronization-semaphores,Semaphores>> section (internal issue
-    251).
-  * Attempt to clarify in the VK_KHR_android_surface extension's
-    <<platformQuerySupport_android,Android Platform Support>> section
-    that there is no Android-specific WSI query, and why (internal issue
-    252).
-
-Other Commits:
-
-  * Add missing language about ename:VK_INCOMPLETE being returned from
-    array queries when the passed array is too short, in the
-    VK_KHR_display, VK_KHR_swapchain, and VK_KHR_surface extensions.
-
------------------------------------------------------
-
-Change log for March 25, 2016 Vulkan 1.0.7 spec update:
-
-  * Bump API patch number and header version number to 7 for this
-    update.
-
-Github Issues:
-
-  * Fix slink:VkSpecializationMapEntry example to avoid C/C++ strict
-    aliasing issues (public issue 14).
-  * Clarify the meaning of "matching" in flink:vkCmdBindDescriptorSets
-    validity language (public issue 33).
-  * Add stub reference pages so xrefs to not-yet-written pages do not
-    generate 404 errors. However, the actual content of these pages
-    still needs to be filled in as time allows (public issue 44, but
-    does not close that issue out).
-  * Remove incorrect validity statement for
-    flink:vkGetImageSparseMemoryRequirements (public issue 85).
-  * Reword the
-    <<features-limits-bufferImageGranularity,bufferImageGranularity>>
-    feature in terms of "aliasing", and clarify that it applies to
-    bindings in the same memory object (public issue 90).
-  * Clarify the relationship of the slink:VkPhysicalDeviceLimits
-    pname:maxViewportDimensions and pname:viewportBoundsRange limits
-    (public issue 92).
-  * Specify sparse unbound texture replacement in the
-    <<textures-texel-replacement,Texel Replacement>> section
-    independently of robust buffer access language (public issue 100).
-  * Add the <<fundamentals-architecture-model,Architecture Model>>
-    section to explain architecture constraints Vulkan has chosen to
-    accept in order to enable portable and performant code (public issue
-    122).
-  * State that an object must not be destroyed until *all* (not *any*)
-    uses of that object have completed (public issue 123).
-  * Minor editorial cleanup (public issues 129, 134, 146, 148).
-  * Add validity language for layer and extension names to
-    slink:VkDeviceCreateInfo matching that used for
-    slink:VkInstanceCreateInfo (public issue 130).
-  * Clean up terminology for the case when the bits set in one bitmask
-    are a subset of the bits set in another bitmask (public issue 138).
-  * Document that input attachments are UniformConstant not Input, in
-    the <<interfaces-inputattachment,Fragment Input Attachment
-    Interface>> section (public glslang bug 169).
-
-Internal Issues:
-
-  * Add max enum values to "flag bits" enums (internal issue 136).
-  * Clarify language around the various uses of the term "block" in the
-    <<appendix-compressedtex-bc,Block Compressed Image Formats>> section
-    (internal issue 202).
-  * Removed "expand" dependency from <enums> groups in vk.xml and added
-    auto-generation code in the scripts to infer it instead, to ensure
-    consistency. This caused renaming of sname:VkColorSpaceKHR and
-    sname:VkPresentModeKHR etext:BEGIN_RANGE (etc.) tokens, but those
-    tokens are metadata, not part of the API, and the Vulkan WG is OK
-    with this change. This change adds ranges to two additional enums
-    that were missing them due to not defining the "expand" attribute
-    (internal issue 217).
-  * Tweak makefile to generate ref page nroff (.3) files in the right
-    output directory, working around an a2x limitation (internal issue
-    223).
-
-Other Commits:
-
-  * Add validity requirements for flink:vkCmdCopyQueryPoolResults
-    pname:dstBuffer parameter.
-  * Fix ref page build to generate .3 targets in the right output
-    directory.
-
------------------------------------------------------
-
-Change log for March 10, 2016 Vulkan 1.0.6 spec update:
-
-  * Bump API patch number and header version number to 6 for this
-    update.
-
-Github Issues:
-
-  * Define 'invocation group' for compute and graphics shaders. Cleanup
-    definition and use of 'workgroup', and add glossary entries (public
-    issue 1).
-  * Various minor editorial fixes (public issue 33).
-  * Clarify locations for block members in the
-    <<interfaces-iointerfaces-locations,Location Assignment>>
-    section (public issue 45).
-  * Editorial fixes for <<commandbuffer-allocation,Command Buffer
-    Allocation>> section (public issues 54, 59).
-  * Clarify behavior of depth test in the <<fragops-depth,Depth Test>>
-    section (public issues 80, 81).
-  * Remove discussion of return codes from
-    flink:vkGetPhysicalDeviceSparseImageFormatProperties and
-    flink:vkGetImageSparseMemoryRequirements, which do not return values
-    (public issue 82).
-  * Allow flink:vkCmdDrawIndirect and flink:vkCmdDrawIndexedIndirect
-    pname:drawCount of 0, as well as 1, when the multiDrawIndirect
-    feature is not supported (public issue 88).
-  * Remove confusing wording in the <<features-limits,Limits>>
-    section describing the slink:VkPhysicalDeviceLimits
-    pname:minTexelBufferOffsetAlignment,
-    pname:minUniformBufferOffsetAlignment, and
-    pname:minStorageBufferOffsetAlignment members as both minimums and
-    maximums (public issue 91).
-  * Clarified that only the RGB components should be affected in places
-    where sRGB is referred to in the spec, such as ASTC formats. Minor
-    re-wording to avoid "color space" when actively incorrect, now that
-    we refer to the Data Format Spec which actually makes a distinction
-    between color space and transfer function (public issue 94).
-  * Treat pname:pPropertyCount == 0 consistently in
-    flink:vkEnumerateInstanceLayerProperties and
-    flink:vkEnumerateDeviceLayerProperties (public issue 99)
-  * Cleanup minor editorial issues in chapters 14-17 (public issue 100).
-  * Clarify definition of flink:vkEnumerateInstanceExtensionProperties
-    and flink:vkEnumerateDeviceExtensionProperties (public issue 101).
-  * Define the flink:vkEnumerateInstanceExtensionProperties and
-    flink:vkEnumerateDeviceExtensionProperties pname:pLayerName
-    parameter to be a pointer to a null-terminated UTF-8 string (public
-    issue 101).
-  * Rearrange "Missing information" references in mandatory format
-    tables (public issue 101).
-  * Clarify that the enumerated extensions returned by
-    flink:vkEnumerateInstanceExtensionProperties and
-    flink:vkEnumerateDeviceExtensionProperties will only include
-    extensions provided by the platform or extensions implemented in
-    implicitly enabled layers (public issue 101).
-  * Miscellaneous editorial fixes. Include the Vulkan spec patch number
-    in the PDF title. Fix label on <<fig-non-strict-lines,Non
-    strict lines>> diagram. Use more easily distinguished symbols in
-    tables in the <<features-required-format-support,Required
-    Format Support>> section. Do not require FQDNs used as layer names be
-    encoded in lower case if not possible, in the
-    <<extensions-naming-conventions, Extension and Layer Naming
-    Conventions>> section (public issues 101, 119, 121).
-
-Internal Issues:
-
-  * Fixed excessive spacing in tables in XHTML (internal issue 18).
-  * Clarify that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT
-    applies to secondary command buffers. Previously spec only referred
-    to the members of pname:pCommandBuffers being affected by this bit.
-    Added a separate slink:VkSubmitInfo Valid Usage restriction
-    specifying that ename:VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT
-    also applies to any secondary command buffers that are recorded into
-    the primary command buffers in pname:pCommandBuffers (internal issue
-    106).
-  * Clarify that slink:VkDeviceCreateInfo::pname:pEnabledFeatures can be
-    NULL (internal issue 117).
-  * Remove "the value of" where it is redundant (e.g. speaking of an API
-    parameter, struct member, or SPIR-V variable, but not when speaking
-    of color components) (internal issue 175).
-  * Forced patch version to always be 0 in the header. Add a
-    "VK_API_VERSION_<major>_<minor>" macro for people to use to do the
-    right thing. Add a VK_HEADER_VERSION which captures the header
-    release number independent of the spec patch number (internal issue
-    176).
-  * Correct description of
-    slink:VkPipelineShaderStageCreateInfo::pname:pName to "a pointer to
-    a null-terminated UTF-8 string" (internal issue 197).
-
-Other Commits:
-
-  * Updated DataFormat spec reference to the new date for revision 5 of
-    that spec.
-  * Fixed KEEP option (to retain LaTeX intermediate files) in the
-    Makefile to be included when edited there, as well as set on the
-    command line.
-  * Reserve and add "VK_IMG_filter_cubic" to the registry, and implement
-    script functionality to add and remove validity from existing
-    functions. Includes schema and readme changes.
-  * Update GL_KHR_vulkan_glsl so push_constants do not have descriptor
-    sets.
-
------------------------------------------------------
-
-Change log for March 4, 2016 Vulkan 1.0.5 spec update:
-
-  * Bump API patch number to 5 for this update.
-
-Github Issues:
-
-  * Correctly describe slink:VkPhysicalDeviceProperties pname:deviceName
-    member as a string, not a pointer to a string. Also one typo fix for
-    "hetereogeneous" (public issue 4).
-  * Replace maynot: macro with may: not, and "may: or maynot:" with
-    "may:" (public issue 4).
-  * Clarify that redundantly setting the state of a fence or event has
-    no effect (public issue 4).
-  * Minor fixes to ref pages to track descriptions of memory bits that
-    changed in the core spec. Fix name of a member in the description of
-    sname:sname:VkPipelineMultisampleStateCreateInfo (public issues 8,
-    13).
-  * Remove redundant validity statement for
-    sname:VkGraphicsPipelineCreateInfo::pname:stageCount (public issue
-    14).
-  * Fix typos in chapters 7-9 (public issue 14).
-  * Clarify the example demonstrating the behavior of
-    code:OpMemoryBarrier in the
-    <<shaders-execution-memory-ordering,shader memory acces
-    ordering>> section (public issue 16).
-  * Specify that freeing mapped memory implicitly unmaps the memory in
-    the description of flink:vkFreeMemory (public issue 17).
-  * Forbid allocation callbacks from calling into the API in the
-    <<memory-allocation,memory allocation>> section (public issue
-    20).
-  * Add missing validity rules about size being greater than 0 and
-    offset being less than size of object. Fix
-    flink:VkMappedMemoryRange's misinterpretation of offset (public
-    issues 27, 31).
-  * Add validity rule disallowing overlapping source/destination
-    descriptors in flink:VkCopyDescriptorSet (public issue 32).
-  * Clarify that array and matrix stride has to be a multiple of the
-    base alignment of the array or matrix in the
-    <<interfaces-resources-layout,Offset and Stride Assignment>>
-    section (public issue 38).
-  * Correct parenthesis floor nesting error in equation for
-    <<textures-RGB-sexp,RGB to shared exponent conversion>>.
-    Clarify case of when exp' is forced to 0, avoiding log2(0) undefined
-    problem (public issue 40).
-  * Remove redundant statement from the code:FragDepth description in
-    the <<interfaces-builtin-variables,Built-In Variables>>
-    section (public issue 47).
-  * Define the clamping of the
-    <<textures-level-of-detail-operation,bias added to the scale
-    factor>> by linking to the slink:VkPhysicalDevice feature
-    pname:maxSamplerLodBias (public issue 64).
-  * Fix typo "optimal linear resources" and clarify the set of resources
-    <<features-limits-bufferImageGranularity,the
-    pname:bufferImageGranularity resource>> applies to (public issue
-    67).
-  * Replace 'descriptor accessed by a pipeline' language for
-    sname:VkDescriptorSetAllocateInfo with more precise phrasing about
-    binding a descriptor set before a command that invokes work using
-    that set (public issue 69).
-  * tstripadj.svg contained an Inkscape tag which caused Firefox and IE
-    11 to fail to render it, and was illegal SVG. Generating Plain SVG
-    from the Inkscape SVG source fixes this (public issue 70).
-  * Fix validity for sname:VkVertexInputBindingDescription and
-    sname:VkVertexInputAttributeDescription numbers (public issue 72).
-
-Internal Issues:
-
-  * Clarify the meaning of
-    ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT in
-    elink:VkFormatFeatureFlagBits with respect to depth compare
-    (internal issue 107).
-  * Added a note explaining that ename:VK_QUEUE_TRANSFER_BIT may or may
-    not be reported for a queue family that already supports
-    ename:VK_QUEUE_GRAPHICS_BIT or ename:VK_QUEUE_COMPUTE_BIT as the
-    former is a strict subset of the latter ones (internal issue 116).

-  * Update GL_KHR_vulkan_glsl with 1) origin_upper_left as default 2)
-    specialization array constant semantics.
-  * Corrected/updated Data Format Specification date.
-
------------------------------------------------------
-
-Change log for February 25, 2015 Vulkan 1.0.4 spec update:
-
-  * Bump API patch number from 3 to 4 for the first public update to the
-    spec. Add patch number to the spec title (this will be done
-    automatically from XML, later).
-  * Fixes for numerous editorial issues. Regularize descriptions of
-    variable-length array queries. Properly tag enumerants so they come
-    out in the right font (many were mislabeled in usage tags in vk.xml,
-    or not tagged). Spelling and markup corrections (public issue 4).
-  * Fix typos and clearly separate description of different types of
-    memory areas (public issue 5).
-  * Use standards-compliant preprocessor guard symbols on headers
-    (public issue 7).
-  * Note that Github users cannot currently set labels on issues, and
-    recommend a fallback approach (public issue 15).
-  * Use latexmath prefix on len= attributes (public issue 29).
-  * Make flink:vkCmdUpdateBuffer pname:dataSize limit consistent (public
-    issue 65).
-  * Add VK_KHR_mirror_clamp_to_edge extension to core API branch, as an
-    optional feature not introducing new commands or enums (internal
-    issue 104).
-  * Cleanup invariance language inherited from the GL specification to
-    not refer to nonexistent (GL-specific) state (internal issue 111).
-  * Modify the flink:vkCmdDrawIndexed pname:vertexOffset definition to
-    not be the "base offset within the index buffer" but rather the
-    "value added to the vertex index before indexing into the vertex
-    buffer" (internal issue 118).
-  * Fix drawing chapter in the "Programmable Primitive Shading" section
-    where it described categories of drawing commands. It referenced
-    flink:vkCmdDrawIndexed twice. Replace the second reference with
-    flink:vkCmdDrawIndexedIndirect (internal issue 119).
-  * Typo fixed in <<sparsememory-examples-advanced,Advanced Sparse
-    Resources>> sparse memory example (internal issue 122).
-  * Add flink:VkDisplayPlaneAlphaFlagsKHR to <require> section of
-    VK_KHR_display extension (internal issue 125)
-  * Add missing optional="false,true" to
-    flink:vkGetImageSparseMemoryRequirements
-    pname:pSparseMemoryRequirementCount parameter (internal issue 132)
-  * Rename ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CREATE_INFO_EXT to
-    ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CALLBACK_CREATE_INFO_EXT
-    (internal issue 133)
-  * Fix a handful of broken cross-references in the
-    <<samplers,Samplers>> chapter (internal issue 134).
-  * Fix "Input Attachement" GLSL example to use correct syntax (internal
-    issue 135).
-  * Update XML schema and documentation to accommodate recently added
-    attributes for validity. Add some introductory material describing
-    design choices and pointing to the public repository to file issues.
-  * Put include of validity in the core spec extensions chapter on its
-    own line, so that asciidoc is happy.
-  * Fix vertexOffset language to specify that it is the value added to
-    the vertex index before indexing into the vertex buffer, not the
-    base offset within the index buffer.
-  * Fix error in the description of flink:vkCmdNextSubpass.

-or legal advice. Distribution of Creative Commons public licenses does not
-create a lawyer-client or other relationship. Creative Commons makes its licenses
-and related information available on an "as-is" basis. Creative Commons gives
-no warranties regarding its licenses, any material licensed under their terms
-and conditions, or any related information. Creative Commons disclaims all
-liability for damages resulting from their use to the fullest extent possible.
-
-Using Creative Commons Public Licenses
-
-Creative Commons public licenses provide a standard set of terms and conditions
-that creators and other rights holders may use to share original works of
-authorship and other material subject to copyright and certain other rights
-specified in the public license below. The following considerations are for
-informational purposes only, are not exhaustive, and do not form part of our
-licenses.
-
-Considerations for licensors: Our public licenses are intended for use by
-those authorized to give the public permission to use material in ways otherwise
-restricted by copyright and certain other rights. Our licenses are irrevocable.
-Licensors should read and understand the terms and conditions of the license
-they choose before applying it. Licensors should also secure all rights necessary
-before applying our licenses so that the public can reuse the material as
-expected. Licensors should clearly mark any material not subject to the license.
-This includes other CC-licensed material, or material used under an exception
-or limitation to copyright. More considerations for licensors : wiki.creativecommons.org/Considerations_for_licensors
-
-Considerations for the public: By using one of our public licenses, a licensor
-grants the public permission to use the licensed material under specified
-terms and conditions. If the licensor's permission is not necessary for any
-reason–for example, because of any applicable exception or limitation to copyright–then
-that use is not regulated by the license. Our licenses grant only permissions
-under copyright and certain other rights that a licensor has authority to
-grant. Use of the licensed material may still be restricted for other reasons,
-including because others have copyright or other rights in the material. A
-licensor may make special requests, such as asking that all changes be marked
-or described. Although not required by our licenses, you are encouraged to
-respect those requests where reasonable. More considerations for the public
-: wiki.creativecommons.org/Considerations_for_licensees Creative Commons Attribution
-4.0 International Public License
-
-By exercising the Licensed Rights (defined below), You accept and agree to
-be bound by the terms and conditions of this Creative Commons Attribution
-4.0 International Public License ("Public License"). To the extent this Public
-License may be interpreted as a contract, You are granted the Licensed Rights
-in consideration of Your acceptance of these terms and conditions, and the
-Licensor grants You such rights in consideration of benefits the Licensor
-receives from making the Licensed Material available under these terms and
-conditions.
-
-Section 1 – Definitions.
-
-a. Adapted Material means material subject to Copyright and Similar Rights
-that is derived from or based upon the Licensed Material and in which the
-Licensed Material is translated, altered, arranged, transformed, or otherwise
-modified in a manner requiring permission under the Copyright and Similar
-Rights held by the Licensor. For purposes of this Public License, where the
-Licensed Material is a musical work, performance, or sound recording, Adapted
-Material is always produced where the Licensed Material is synched in timed
-relation with a moving image.
-
-b. Adapter's License means the license You apply to Your Copyright and Similar
-Rights in Your contributions to Adapted Material in accordance with the terms
-and conditions of this Public License.
-
-c. Copyright and Similar Rights means copyright and/or similar rights closely
-related to copyright including, without limitation, performance, broadcast,
-sound recording, and Sui Generis Database Rights, without regard to how the
-rights are labeled or categorized. For purposes of this Public License, the
-rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.
-
-d. Effective Technological Measures means those measures that, in the absence
-of proper authority, may not be circumvented under laws fulfilling obligations
-under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996,
-and/or similar international agreements.
-
-e. Exceptions and Limitations means fair use, fair dealing, and/or any other
-exception or limitation to Copyright and Similar Rights that applies to Your
-use of the Licensed Material.
-
-f. Licensed Material means the artistic or literary work, database, or other
-material to which the Licensor applied this Public License.
-
-g. Licensed Rights means the rights granted to You subject to the terms and
-conditions of this Public License, which are limited to all Copyright and
-Similar Rights that apply to Your use of the Licensed Material and that the
-Licensor has authority to license.
-
-h. Licensor means the individual(s) or entity(ies) granting rights under this
-Public License.
-
-i. Share means to provide material to the public by any means or process that
-requires permission under the Licensed Rights, such as reproduction, public
-display, public performance, distribution, dissemination, communication, or
-importation, and to make material available to the public including in ways
-that members of the public may access the material from a place and at a time
-individually chosen by them.
-
-j. Sui Generis Database Rights means rights other than copyright resulting
-from Directive 96/9/EC of the European Parliament and of the Council of 11
-March 1996 on the legal protection of databases, as amended and/or succeeded,
-as well as other essentially equivalent rights anywhere in the world.
-
-k. You means the individual or entity exercising the Licensed Rights under
-this Public License. Your has a corresponding meaning.
-
-Section 2 – Scope.
-
-   a. License grant.
-
-1. Subject to the terms and conditions of this Public License, the Licensor
-hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive,
-irrevocable license to exercise the Licensed Rights in the Licensed Material
-to:
-
-         A. reproduce and Share the Licensed Material, in whole or in part; and
-
-         B. produce, reproduce, and Share Adapted Material.
-
-2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions
-and Limitations apply to Your use, this Public License does not apply, and
-You do not need to comply with its terms and conditions.
-
-      3. Term. The term of this Public License is specified in Section 6(a).
-
-4. Media and formats; technical modifications allowed. The Licensor authorizes
-You to exercise the Licensed Rights in all media and formats whether now known
-or hereafter created, and to make technical modifications necessary to do
-so. The Licensor waives and/or agrees not to assert any right or authority
-to forbid You from making technical modifications necessary to exercise the
-Licensed Rights, including technical modifications necessary to circumvent
-Effective Technological Measures. For purposes of this Public License, simply
-making modifications authorized by this Section 2(a)(4) never produces Adapted
-Material.
-
-      5. Downstream recipients.
-
-A. Offer from the Licensor – Licensed Material. Every recipient of the Licensed
-Material automatically receives an offer from the Licensor to exercise the
-Licensed Rights under the terms and conditions of this Public License.
-
-B. No downstream restrictions. You may not offer or impose any additional
-or different terms or conditions on, or apply any Effective Technological
-Measures to, the Licensed Material if doing so restricts exercise of the Licensed
-Rights by any recipient of the Licensed Material.
-
-6. No endorsement. Nothing in this Public License constitutes or may be construed
-as permission to assert or imply that You are, or that Your use of the Licensed
-Material is, connected with, or sponsored, endorsed, or granted official status
-by, the Licensor or others designated to receive attribution as provided in
-Section 3(a)(1)(A)(i).
-
-   b. Other rights.
-
-1. Moral rights, such as the right of integrity, are not licensed under this
-Public License, nor are publicity, privacy, and/or other similar personality
-rights; however, to the extent possible, the Licensor waives and/or agrees
-not to assert any such rights held by the Licensor to the limited extent necessary
-to allow You to exercise the Licensed Rights, but not otherwise.
-
-2. Patent and trademark rights are not licensed under this Public License.
-
-3. To the extent possible, the Licensor waives any right to collect royalties
-from You for the exercise of the Licensed Rights, whether directly or through
-a collecting society under any voluntary or waivable statutory or compulsory
-licensing scheme. In all other cases the Licensor expressly reserves any right
-to collect such royalties.
-
-Section 3 – License Conditions.
-
-Your exercise of the Licensed Rights is expressly made subject to the following
-conditions.
-
-   a. Attribution.
-
-1. If You Share the Licensed Material (including in modified form), You must:
-
-A. retain the following if it is supplied by the Licensor with the Licensed
-Material:
-
-i. identification of the creator(s) of the Licensed Material and any others
-designated to receive attribution, in any reasonable manner requested by the
-Licensor (including by pseudonym if designated);
-
-            ii. a copyright notice;
-
-            iii. a notice that refers to this Public License;
-
-            iv. a notice that refers to the disclaimer of warranties;
-
-v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;
-
-B. indicate if You modified the Licensed Material and retain an indication
-of any previous modifications; and
-
-C. indicate the Licensed Material is licensed under this Public License, and
-include the text of, or the URI or hyperlink to, this Public License.
-
-2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner
-based on the medium, means, and context in which You Share the Licensed Material.
-For example, it may be reasonable to satisfy the conditions by providing a
-URI or hyperlink to a resource that includes the required information.
-
-3. If requested by the Licensor, You must remove any of the information required
-by Section 3(a)(1)(A) to the extent reasonably practicable.
-
-4. If You Share Adapted Material You produce, the Adapter's License You apply
-must not prevent recipients of the Adapted Material from complying with this
-Public License.
-
-Section 4 – Sui Generis Database Rights.
-
-Where the Licensed Rights include Sui Generis Database Rights that apply to
-Your use of the Licensed Material:
-
-a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract,
-reuse, reproduce, and Share all or a substantial portion of the contents of
-the database;
-
-b. if You include all or a substantial portion of the database contents in
-a database in which You have Sui Generis Database Rights, then the database
-in which You have Sui Generis Database Rights (but not its individual contents)
-is Adapted Material; and
-
-c. You must comply with the conditions in Section 3(a) if You Share all or
-a substantial portion of the contents of the database.
-
-For the avoidance of doubt, this Section 4 supplements and does not replace
-Your obligations under this Public License where the Licensed Rights include
-other Copyright and Similar Rights.
-
-Section 5 – Disclaimer of Warranties and Limitation of Liability.
-
-a. Unless otherwise separately undertaken by the Licensor, to the extent possible,
-the Licensor offers the Licensed Material as-is and as-available, and makes
-no representations or warranties of any kind concerning the Licensed Material,
-whether express, implied, statutory, or other. This includes, without limitation,
-warranties of title, merchantability, fitness for a particular purpose, non-infringement,
-absence of latent or other defects, accuracy, or the presence or absence of
-errors, whether or not known or discoverable. Where disclaimers of warranties
-are not allowed in full or in part, this disclaimer may not apply to You.
-
-b. To the extent possible, in no event will the Licensor be liable to You
-on any legal theory (including, without limitation, negligence) or otherwise
-for any direct, special, indirect, incidental, consequential, punitive, exemplary,
-or other losses, costs, expenses, or damages arising out of this Public License
-or use of the Licensed Material, even if the Licensor has been advised of
-the possibility of such losses, costs, expenses, or damages. Where a limitation
-of liability is not allowed in full or in part, this limitation may not apply
-to You.
-
-c. The disclaimer of warranties and limitation of liability provided above
-shall be interpreted in a manner that, to the extent possible, most closely
-approximates an absolute disclaimer and waiver of all liability.
-
-Section 6 – Term and Termination.
-
-a. This Public License applies for the term of the Copyright and Similar Rights
-licensed here. However, if You fail to comply with this Public License, then
-Your rights under this Public License terminate automatically.
-
-b. Where Your right to use the Licensed Material has terminated under Section
-6(a), it reinstates:
-
-1. automatically as of the date the violation is cured, provided it is cured
-within 30 days of Your discovery of the violation; or
-
-      2. upon express reinstatement by the Licensor.
-
-c. For the avoidance of doubt, this Section 6(b) does not affect any right
-the Licensor may have to seek remedies for Your violations of this Public
-License.
-
-d. For the avoidance of doubt, the Licensor may also offer the Licensed Material
-under separate terms or conditions or stop distributing the Licensed Material
-at any time; however, doing so will not terminate this Public License.
-
-   e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.
-
-Section 7 – Other Terms and Conditions.
-
-a. The Licensor shall not be bound by any additional or different terms or
-conditions communicated by You unless expressly agreed.
-
-b. Any arrangements, understandings, or agreements regarding the Licensed
-Material not stated herein are separate from and independent of the terms
-and conditions of this Public License.
-
-Section 8 – Interpretation.
-
-a. For the avoidance of doubt, this Public License does not, and shall not
-be interpreted to, reduce, limit, restrict, or impose conditions on any use
-of the Licensed Material that could lawfully be made without permission under
-this Public License.
-
-b. To the extent possible, if any provision of this Public License is deemed
-unenforceable, it shall be automatically reformed to the minimum extent necessary
-to make it enforceable. If the provision cannot be reformed, it shall be severed
-from this Public License without affecting the enforceability of the remaining
-terms and conditions.
-
-c. No term or condition of this Public License will be waived and no failure
-to comply consented to unless expressly agreed to by the Licensor.
-
-d. Nothing in this Public License constitutes or may be interpreted as a limitation
-upon, or waiver of, any privileges and immunities that apply to the Licensor
-or You, including from the legal processes of any jurisdiction or authority.
-
-Creative Commons is not a party to its public licenses. Notwithstanding, Creative
-Commons may elect to apply one of its public licenses to material it publishes

-= Vulkan^(R)^ API Documentation Project
-
-This repository contains sources for the formal documentation of the Vulkan
-API. This includes:
-
-[options="compact"]
- * The Vulkan API Specification
- * Specification of Vulkan extensions
- * API reference ("`man`") pages
- * The XML API Registry (also mirrored at
-   link:https://github.com/KhronosGroup/Vulkan-Headers[Vulkan-Headers])
- * Vulkan header files (also mirrored at
-   link:https://github.com/KhronosGroup/Vulkan-Headers[Vulkan-Headers])
- * Related tools and scripts.
-
-The authoritative public repository is located at
-link:https://github.com/KhronosGroup/Vulkan-Docs/[Vulkan-Docs].
-It hosts a public Issue tracker, and outside developers can file proposed
-changes (Pull Requests) against the Specification, subject to approval by
-Khronos.
-
-If in doubt where to submit your Issue, consult the
-link:https://github.com/KhronosGroup/Vulkan-Web-Registry/blob/main/Vulkan-Projects.adoc[Vulkan-Projects] list on the link:https://github.com/KhronosGroup/Vulkan-Web-Registry[Vulkan-Web-Registry] 
-repository.
-
-
-== External Contributions
-
-Khronos welcomes feedback in Github Issues, and proposed changes in Github
-Pull Requests (PRs), but will not necessarily accept all such changes.
-
-Please keep your issues and pull requests focused on solving a single
-problem. Broader feedback that tries to solve multiple problems, or touches
-many parts of the Specification at once, is difficult for the Vulkan Working
-Group to review in a timely fashion.
-
-
-== Branch Structure
-
-The current Specification is maintained in the default branch (currently
-`main`) of the repository.
-From this branch it is possible to generate Specifications for any published
-version of Vulkan (1.2, 1.1, and 1.0), and incorporating any desired set of
-extensions.
-Each published update is tagged in the form `1.2.*release*` where *release*
-is a constantly incrementing release number and `1.2` is the latest
-published version of the API.
-The last public spec update prior to Vulkan 1.2 is tagged `v1.1.130`.
-
-The last state of the default branch in Khronos' internal gitlab server,
-before 1.2 content was merged into it, is tagged `1.1-archive` (this tag is
-not in github).
-
-
-== Directory Structure
-
-The directory structure is as follows:
-
-```
-README.adoc           This file
-BUILD.adoc            Documents how to build the specifications and reference pages
-CONTRIBUTING.adoc     Requirements for external contributions to the repository
-COPYING.adoc          Copyright and licensing information
-CODE_OF_CONDUCT.adoc  Code of Conduct
-LICENSE.adoc          Summary of licenses used by files in the repository
-ChangeLog.txt         Change log summary for each public spec update
-Makefile, make*       Makefile and helper build scripts (see BUILD.adoc)
-appendices/           Specification appendices
-chapters/             Specification chapters
-proposals/            Design documents for extensions
-config/               Asciidoctor configuration, CSS, and index generator
-images/               Images (figures, diagrams, icons)
-gen/out/              Default directory for the generated documents
-scripts/              Helper scripts used in specification, header, and reference page generation
-style/                Sources for "styleguide" (Vulkan Documentation and Extensions: Procedures and Conventions)
-xml/                  XML API Registry (vk.xml)
-registry.txt          Sources for documentation of the vk.xml format
-```
-
-
-== Building the Specification and Reference Pages
-
-The document sources are marked up in Asciidoctor format, and we use
-`asciidoctor` and related toolchain components to generate output documents.
-See link:BUILD.adoc[BUILD.adoc] for more information on installing the
-toolchain and building the Specification.
-
-
-== Generating Headers and Related Files
-
-See link:xml/README.adoc[xml/README.adoc].
-
-The header files (`include/vulkan/vulkan*.h`) and many parts of the
-specification and reference page documents are generated from descriptions
-in the XML API Registry (link:xml/vk.xml[`xml/vk.xml`]).
-The generated files are not checked into the repository.
-If you change `vk.xml`, you can regenerate the headers by going into
-`xml/` and running:
-
-    $ make clean install
-
-The other generated files are built as required via dependencies in
-the top-level `Makefile`.

-[[introduction]]
-= Introduction
-
-This document describes the Khronos Vulkan API Registry schema, and provides
-some additional information about using the registry and scripts to generate
-a variety of outputs, including C header files as well as several types of
-asciidoc include files used in the Vulkan API specification and reference
-pages.
-The underlying XML files and scripts are located on the Khronos public
-Github server at URL
-
-https://github.com/KhronosGroup/Vulkan-Docs
-
-The authoritative copy of the Registry is maintained in the default branch,
-currently `main`.
-
-The registry uses an XML representation of the Vulkan API, together with a
-set of Python scripts to manipulate the registry once loaded.
-The scripts rely on the Python `etree` package to parse and operate on XML.
-An XML schema and validator target are included.
-
-The schema is based on, but not identical to that used for the previously
-published OpenGL, OpenGL ES and EGL API registries.
-It was extended to represent additional types and concepts not needed for
-those APIs, such as structure and enumerant types, as well as additional
-types of registered information specific to Vulkan.
-
-The Vulkan C header files generated from the registry are checked into a
-separate repository under
-
-https://github.com/KhronosGroup/Vulkan-Headers/
-
-
-== Schema Choices
-
-The XML schema is not pure XML all the way down.
-In particular, command return types/names and parameters, and structure
-members, are described in mixed-mode tag containing C declarations of the
-appropriate information, with some XML nodes annotating particular parts of
-the declaration such as its base type and name.
-This choice is based on prior experience with the SGI `.spec` file format
-used to describe OpenGL, and greatly eases human reading and writing the
-XML, and generating C-oriented output.
-The cost is that people writing output generators for other languages will
-have to include enough logic to parse the C declarations and extract the
-relevant information.
-
-People who do not find the supplied Python scripts to suit their needs are
-likely to write their own parsers, interpreters, and/or converters operating
-on the registry XML.
-We hope that we have provided enough information in this document, the RNC
-schema (`registry.rnc`), and comments in the Registry (`vk.xml`) itself to
-enable such projects.
-If not and you need clarifications; if you have other problems using the
-registry; or if you have proposed changes and enhancements, then please file
-issues on Khronos' public Github project at
-
-https://github.com/KhronosGroup/Vulkan-Docs/issues
-
-Please tag your issues with `[Registry]` in the subject line to help us
-categorize them.
-We have considered separating the registry from the specification source
-into a separate repository, but since there is so much specification valid
-usage language imbedded in the registry XML, this is unlikely to happen.
-
-
-[[starting]]
-= Getting Started
-
-See
-https://gitlab.khronos.org/vulkan/vulkan/blob/main/xml/README.adoc[`xml/README.adoc`]
-in the `Vulkan-Docs` repository for information on required toolchain
-components such as Python 3, pass:[g++], and GNU make.
-
-Once you have the right tools installed, perform the following steps:
-
-  * Check out the `Vulkan-Docs` repository linked above from Khronos Github
-    (there are instructions at the link)
-  * `cd` to the root directory in your checked-out repo
-  * Switch to the default branch (`main`).
-  * Invoke `make clean ; make install ; make test`
-
-This should regenerate `vulkan_core.h` and a variety of platform-specific
-headers, install them in `../include/vulkan/`, and verify that the headers
-build properly.
-If you build at the latest repository tag, the resulting headers should be
-identical to the latest versions in the
-link:https://github.com/KhronosGroup/Vulkan-Headers/[Vulkan-Headers
-repository].
-
-The `install` target also generates source code for a simple extension
-loader library in `../src/ext_loader/`.
-
-Other Makefile targets in `xml/` include:
-
-  * `validate` - validate `vk.xml` against the XML schema.
-    Recommended if you are making nontrivial changes.
-  * The asciidoc includes used by the Specification and Reference Pages are
-    built using the 'make generated' target in the parent directory
-    Makefile, although they use the scripts and XML in this directory.
-    These files are generated dynamically when building the specs, since
-    their contents depend on the exact set of extensions the Specification
-    is being built to include.
-
-If you just want to modify the API, changing `vk.xml` and running `make`
-should be all that is needed.
-See <<examples>> for some examples of modifying the XML.
-
-If you want to use the registry for reasons other than generating the header
-file, extension loader, and asciidoc includes, or to generate headers for
-languages other than C, start with the Makefile rules and the files
-`vk.xml` and scripts `genvk.py`, `reg.py`, and `generator.py`.
-The scripts are described below and are all located in the `scripts`
-directory under the repository root.
-
-== Header Generation Script - `genvk.py`
-
-When generating header files using the `genvk.py` script, an API name and
-profile name are required, as shown in the Makefile examples.
-Additionally, specific API versions and extensions can be required or
-excluded.
-Based on this information, the generator script extracts the relevant
-interfaces and creates a C-language header file for them.
-`genvk.py` contains predefined generator options for the current Vulkan
-Specification release.
-
-The generator script is intended to be generalizable to other languages by
-writing new generator classes.
-Such generators would have to rewrite the C types and definitions in the XML
-to something appropriate to their language.
-
-
-== Registry Processing Script - `reg.py`
-
-XML processing is done in `reg.py`, which contains several objects and
-methods for loading registries and extracting interfaces and extensions for
-use in header generation.
-There is some internal documentation in the form of comments, although
-nothing more extensive exists yet.
-
-
-== Output Generator Script - `generator.py`
-
-Once the registry is loaded, the `COutputGenerator` class defined in
-`generator.py` is used to create a header file.
-The `DocOutputGenerator` class is used to create the asciidoc include files.
-Output generators for other purposes can be added as needed.
-There are a variety of output generators included:
-
-  * `cgenerator.py` - generate C header file
-  * `docgenerator.py` - generate asciidoc includes for APIs
-  * `hostsyncgenerator.py` - generate host sync table includes for APIs
-  * `validitygenerator.py` - generate validity language includes
-  * `pygenerator.py` - generate a Python dictionary-based encoding of
-    portions of the registry, used during spec generation
-  * `extensionStubSource.py` - generate a simple C extension loader.
-
-
-[[schema]]
-= Vulkan Registry Schema
-
-The format of the Vulkan registry is a top level tag:registry tag containing
-tag:types, tag:enums, tag:commands, tag:feature, and tag:extension tags
-describing the different elements of an API, as explained below.
-This description corresponds to a formal Relax NG schema file,
-`registry.rnc`, against which the XML registry files can be validated.
-
-At present the only registry in this schema is the core Vulkan API registry,
-`vk.xml`.
-
-
-[[schema:profile]]
-== Profiles
-
-Types and enumerants can have different definitions depending on the API
-profile requested.
-This capability is not used in the current Vulkan API but may be in the
-future.
-Features and extensions can include some elements conditionally depending on
-the API profile requested.
-
-
-[[schema:apiname]]
-== API Names
-
-Specific API versions features and extensions can be tagged as belonging to
-to classes of features with the use of _API names_.
-This is intended to allow multiple closely-related API specifications in the
-same family - such as desktop and mobile specifications - to share the same
-XML.
-An API name is an arbitrary alphanumeric string, although it should be
-chosen to match the corresponding API.
-For example, Vulkan and OpenXR use `vulkan` and `openxr` as their API names,
-respectively.
-
-The attr:api attribute of the tag:feature tag and the attr:supported
-attribute of the tag:extensions tag must be comma-separated lists of one or
-more API names, all of which match that feature or extension.
-When generating headers and other artifacts from the XML, an API name may be
-specified to the processing scripts, causing the selection of only those
-features and extensions whose API names match the specified name.
-
-Several other tags for defining types and groups of types also support
-attr:api attributes.
-If present, the attribute value must be a comma-separated list of one or
-more API names.
-This allows specializing a definition for different, closely related APIs.
-
-
-[[schema:root]]
-= Registry Root (tag:registry tag)
-
-A tag:registry contains the entire definition of one or more related APIs.
-
-== Attributes of tag:registry tags
-
-None.
-
-== Contents of tag:registry tags
-
-Zero or more of each of the following tags, normally in this order (although
-order should not be important):
-
-  * tag:comment - Contains arbitrary text, such as a copyright statement.
-  * <<tag-platforms,tag:platforms>> - defines platform names corresponding
-    to platform-specific <<tag-extension,API extensions>>.
-  * <<tag-tags,tag:tags>> - defines author IDs used for extensions and
-    layers.
-    Author IDs are described in detail in the "`Layers & Extensions`"
-    section of the "`Vulkan Documentation and Extensions: Procedures and
-    Conventions`" document.
-  * <<tag-types,tag:types>> - defines API types.
-    Usually only one tag is used.
-  * <<tag-enums,tag:enums>> - defines API token names and values.
-    Usually multiple tags are used.
-    Related groups may be tagged as an enumerated type corresponding to a
-    tag:type tag, and resulting in a C `enum` declaration.
-    This ability is heavily used in the Vulkan API.
-  * <<tag-commands,tag:commands>> - defines API commands (functions).
-    Usually only one tag is used.
-  * <<tag-feature,tag:feature>> - defines API feature interfaces (API
-    versions, more or less).
-    One tag per feature set.
-  * <<tag-extensions,tag:extensions>> - defines API extension interfaces.
-    Usually only one tag is used, wrapping many extensions.
-
-
-[[tag-comment]]
-=== Comment Tags (tag:comment tag)
-
-A tag:comment tag contains an arbitrary string, and is unused.
-Comment tags may appear in multiple places in the schema, as described
-below.
-Comment tags are removed by output generators if they would otherwise appear
-in generated headers, asciidoc include files, etc.
-
-
-[[tag-platforms]]
-= Platform Name Blocks (tag:platforms tag)
-
-A tag:platforms contains descriptions of platform IDs for platforms
-supported by window system-specific extensions to Vulkan.
-
-== Attributes of tag:platforms tags
-
-  * attr:comment - optional.
-    Arbitrary string (unused).
-
-== Contents of tag:platforms tags
-
-Zero or more tag:platform tags, in arbitrary order (though they are
-typically ordered by sorting on the platform name).
-
-
-[[tag-platform]]
-= Platform Names (tag:platform tag)
-
-A tag:platform tag describes a single platform name.
-
-== Attributes of tag:platform tags
-
-  * attr:name - required.
-    The platform name.
-    This must be a short alphanumeric string corresponding to the platform
-    name, valid as part of a C99 identifier.
-    Lower-case is preferred.
-    In some cases, it may be desirable to distinguish a subset of platform
-    functionality from the entire platform.
-    In these cases, the platform name should begin with the entire platform
-    name, followed by `_` and the subset name.

-= API Type (tag:type tag)
-
-A tag:type tag contains information which can be used to generate C code
-corresponding to the type.
-In many cases, this is simply legal C code, with attributes or embedded tags
-denoting the type name and other types used in defining this type.
-In some cases, additional attribute and embedded type information is used to
-generate more complicated C types.
-
-== Attributes of tag:type tags
-
-  * attr:requires - optional.
-    Another type name this type requires to complete its definition.
-  * attr:name - optional.
-    Name of this type (if not defined in the tag body).
-  * attr:alias - optional.
-    Another type name which this type is an alias of.
-    Must match the name of another tag:type element.
-    This is typically used when promoting a type defined by an extension to
-    a new core version of the API.
-    The old extension type is still defined, but as an alias of the new
-    type.
-  * attr:api - optional <<schema:apiname, API names>> for which this
-    definition is specialized, so that different APIs may have different
-    definitions for the same type.
-    This definition is only used if the requested API name matches the
-    attribute.
-    May be used to address subtle incompatibilities.
-  * attr:category - optional.
-    A string which indicates that this type contains a more complex
-    structured definition.
-    At present the only accepted categories are `basetype`, `bitmask`,
-    `define`, `enum`, `funcpointer`, `group`, `handle`, `include`, `struct`,
-    and `union`, as described below.
-  * attr:comment - optional.
-    Arbitrary string (unused).
-  * attr:parent - only applicable if `"category"` is `handle`.
-    Notes another type with the `handle` category that acts as a parent
-    object for this type.
-  * attr:returnedonly - only applicable if `"category"` is `struct` or
-    `union`.
-    Notes that this struct/union is going to be filled in by the API, rather
-    than an application filling it out and passing it to the API.
-  * attr:structextends only applicable if category is `struct` or `union`.
-    This is a comma-separated list of structures whose `pNext` can include
-    this type.
-    This should usually only list the top-level structure that is extended,
-    for all possible extending structures.
-    This will generate a validity statement on the top level structure that
-    validates the entire chain in one go, rather than each extending
-    structure repeating the list of valid structs.
-    There is no need to set the attr:noautovalidity attribute on the `pNext`
-    members of extending structures.
-  * attr:allowduplicate - only applicable if attr:category is `"struct"`.
-    If `"true"`, then structures whose `pNext` chains include this structure
-    may include more than one instance of it.
-  * attr:objtypeenum - only applicable at present if attr:category is
-    `"handle"`.
-    Specifies the name of a `VkObjectType` enumerant which corresponds to
-    this type.
-    The enumerant must be defined.
-
-== Contents of tag:type tags
-
-The valid contents depend on the attr:category attribute.
-
-=== Enumerated types - attr:category `"enum"`
-
-If the attr:category tag has the value `enum`, the type is a C enumeration.
-The body of the tag is ignored in this case.
-The value of the attr:name attribute must be provided and must match the
-attr:name attribute of a <<tag-enums,tag:enums>> tag.
-The enumerant values defined within the tag:enums tag are used to generate a
-C `enum` type declaration.
-
-=== Structure types - attr:category `"struct"` or `"union"`
-
-If the attr:category tag has the values `struct` or `union`, the type is a C
-structure or union, respectively.
-In this case, the attr:name attribute must be provided, and the contents of
-the tag:type tag are a series of tag:member tags defining the members of the
-aggregate type, in order, interleaved with any number of tag:comment tags.
-
-==== Structure member (tag:member) tags
-
-The tag:member tag defines the type and name of a structure or union member.
-
-==== Attributes of tag:member tags
-
-  * attr:values - only valid on the `sType` member of a struct.
-    This is a comma-separated list of enumerant values that are valid for
-    the structure type; usually there is only a single value.
-  * attr:len - if the member is an array, len may be one or more of the
-    following things, separated by commas (one for each array indirection):
-    another member of that struct; `"null-terminated"` for a string; `"1"`
-    to indicate it is just a pointer (used for nested pointers); or an
-    equation in math markup for incorporation in the specification (a LaTeX
-    math expression delimited by `latexmath:[` and `]`.
-    The only variables in the equation should be the names of members of the
-    structure.
-  * attr:altlen - if the attr:len attribute is specified, and contains a
-    `latexmath:` equation, this attribute should be specified with an
-    equivalent equation using only C builtin operators, C math library
-    function names, and variables as allowed for attr:len.
-    It must be a valid C99 expression whose result is equal to attr:len for
-    all possible inputs.
-    It is a comma separated list that has size equal to only the `latexmath`
-    item count in attr:len list.
-    This attribute is intended to support consumers of the XML who need to
-    generate validation code from the allowed length.
-  * attr:externsync - denotes that the member should be externally
-    synchronized when accessed by Vulkan
-  * attr:optional - optional.
-    A value of `"true"` or `"false"` determines whether this member can be
-    omitted by providing `NULL` (for pointers), `VK_NULL_HANDLE` (for
-    handles), or 0 (for other scalar types).
-    If the member is a pointer to one of those types, multiple values may be
-    provided, separated by commas - one for each pointer indirection.
-    If not present, the value is assumed to be `"false"` (the member must
-    not be omitted).
-    Structure members with name `pNext` must always be specified with
-    `optional="true"`, since there is no requirement that any member of a
-    `pNext` chain have a following member in the chain.
-+
---
-[NOTE]
-.Note
-====
-While the attr:optional attribute can be used for scalar types such as
-integers, it does not affect the output generators included with the Vulkan
-Specification.
-In this case, the attribute serves only as an indicator to human readers of
-the XML.
-====
---
-  * attr:selector - optional.
-    If the member is a union, attr:selector identifies another member of the
-    struct that is used to select which of that union's members are valid.
-  * attr:selection - optional.
-    For a member of a union, attr:selection identifies a value of the
-    attr:selector that indicates this member is valid.
-  * attr:noautovalidity - prevents automatic validity language being
-    generated for the tagged item.
-    Only suppresses item-specific validity - parenting issues etc.
-    are still captured.
-    It must also be used for structures that have no implicit validity when
-    such structure has explicit validity.
-  * attr:limittype - only applicable for members of
-    VkPhysicalDeviceProperties and VkPhysicalDeviceProperties2, their
-    substrucutres, and extensions.
-    Specifies the type of a device limit.
-    This type describes how a value might be compared with the value of a
-    member in order to check whether it fits the limit.
-    Valid values:
-  ** `"min"` and `"max"` denote minimum and maximum limits.
-     They may also apply to arrays and `VkExtent*D`.
-  ** `"bitmask"` corresponds to bitmasks and `VkBool32`, where set bits
-     indicate the presence of a capability
-  ** `"range"` specifies a [min, max] range
-  ** `"struct"` means that the member's fields should be compared.
-  ** `"noauto"` limits cannot be trivially compared.
-     This is the default value, if unspecified.
-  * attr:objecttype - only applicable for members which are `uint64_t`
-    values representing a Vulkan obejct handle.
-    Specifies the name of another member which must be a `VkObjectType` or
-    `VkDebugReportObjectTypeEXT` value specifying the type of object the
-    handle refers to.
-
-==== Contents of tag:member tags
-
-The text elements of a tag:member tag, with all other tags removed, is a
-legal C declaration of a struct or union member.
-In addition it may contain several semantic tags:
-
-  * The tag:type tag is optional.
-    It contains text which is a valid type name found in another tag:type
-    tag, and indicates that this type must be previously defined for the
-    definition of the command to succeed.
-    Builtin C types should not be wrapped in tag:type tags.
-  * The tag:name tag is required, and contains the struct/union member name
-    being described.
-  * The tag:enum tag is optional.
-    It contains text which is a valid enumerant name found in another
-    tag:type tag, and indicates that this enumerant must be previously
-    defined for the definition of the command to succeed.
-    Typically this is used to semantically tag static array lengths.
-  * The tag:comment tag is optional.
-    It contains an arbitrary string (unused).
-
-
-=== All other types
-
-If the attr:category attribute is one of `basetype`, `bitmask`, `define`,
-`funcpointer`, `group`, `handle` or `include`, or is not specified, tag:type
-contains text which is legal C code for a type declaration.
-It may also contain embedded tags:
-
-  * tag:type - nested type tags contain other type names which are required
-    by the definition of this type.
-  * tag:apientry/ - insert a platform calling convention macro here during
-    header generation, used mostly for function pointer types.
-  * tag:name - contains the name of this type (if not defined in the tag
-    attributes).
-  * tag:bitvalues - contains the name of the enumeration defining flag
-    values for a `bitmask` type.
-    Ignored for other types.
-
-There is no restriction on which sorts of definitions may be made in a given
-category, although the contents of tags with attr:category `enum`, `struct`
-or `union` are interpreted specially as described above.
-
-However, when generating the header, types within each category are grouped
-together, and categories are generated in the order given by the following
-list.
-Therefore, types in a category should correspond to the intended purpose
-given for that category.
-If this recommendation is not followed, it is possible that the resulting
-header file will not compile due to out-of-order type dependencies.
-The intended purpose of each category is:
-
-  * `include` (`#include`) directives)
-  * `define` (macro `#define` directives)
-  * `basetype` (built-in C language types; scalar API typedefs, such as the
-    definition of `VkFlags`; and types defined by external APIs, such as an
-    underlying OS or window system
-  * `handle` (invocations of macros defining scalar types such as
-    `VkInstance`)
-  * `enum` (enumeration types and `#define` for constant values)
-  * `group` (currently unused)
-  * `bitmask` (enumeration types whose members are bitmasks)
-  * `funcpointer` (function pointer typedefs)
-  * `struct` and `union` together (struct and union types)

-== Example of a tag:types tag
-
-[source,xml]
---------------------------------------
-<types>
-    <type name="stddef">#include &lt;stddef.h&gt;</type>
-    <type requires="stddef">typedef ptrdiff_t <name>VKlongint</name>;</type>
-    <type name="VkEnum" category="enum"/>
-    <type category="struct" name="VkStruct">
-        <member><type>VkEnum</type> <name>srcEnum</name></member>
-        <member><type>VkEnum</type> <name>dstEnum</name></member>
-    </type>

-<enums name="VkEnum" type="enum">
-    <enum value="0" name="VK_ENUM_ZERO"/>
-    <enum value="42" name="VK_ENUM_FORTY_TWO"/>
-</enums>
---------------------------------------
-
-The `VkStruct` type is defined to require the types `VkEnum` and `VKlongint`
-as well.
-If `VkStruct` is in turn required by a command or another type during header
-generation, it will result in the following declarations:
-
-[source,c]
---------------------------------------
-#include <stddef.h>
-typedef ptrdiff_t VKlongint.
-
-typedef enum {
-    VK_ENUM_ZERO = 0,
-    VK_ENUM_FORTY_TWO = 42
-} VkEnum;
-
-typedef struct {
-    VkEnum    dstEnum;
-    VkLongint dstVal;
-} VkStruct;
---------------------------------------
-
-Note that the angle brackets around `stddef.h` are represented as XML
-entities in the registry.
-This could also be done using a CDATA block but unless there are many
-characters requiring special representation in XML, using entities is
-preferred.
-
-
-[[tag-enums]]
-= Enumerant Blocks (tag:enums tag)
-
-The tag:enums tags contain individual tag:enum tags describing each of the
-token names used in the API.
-In some cases these correspond to a C `enum`, and in some cases they are
-simply compile time constants (e.g. `#define`).
-
-[NOTE]
-.Note
-====
-It would make more sense to call these `const` or `define` tags.
-This is a historical hangover from the OpenGL XML format which this schema
-was based on.
-====
-
-
-== Attributes of tag:enums tags
-
-  * attr:name - optional.
-    String naming the C `enum` type whose members are defined by this enum
-    group.
-    If present, this attribute should match the attr:name attribute of a
-    corresponding tag:type tag.
-  * attr:type - optional.
-    String describing the data type of the values of this group of enums.
-    At present the only accepted categories are `enum` and `bitmask`, as
-    described below.
-  * attr:start, attr:end - optional.
-    Integers defining the start and end of a reserved range of enumerants
-    for a particular vendor or purpose.
-    attr:start must be less than or equal to attr:end.
-    These fields define formal enumerant allocations, and are made by the
-    Khronos Registrar on request from implementors following the enum
-    allocation policy.
-  * attr:vendor - optional.
-    String describing the vendor or purpose to whom a reserved range of
-    enumerants is allocated.
-  * attr:comment - optional.
-    Arbitrary string (unused).
-  * attr:bitwidth - optional.
-    Bit width required for the generated enum value type.
-    If omitted, a default value of 32 is used.
-
-== Contents of tag:enums tags
-
-Each tag:enums block contains zero or more tag:enum, tag:unused, and
-tag:comment tags, in arbitrary order (although they are typically ordered by
-sorting on enumerant values, to improve human readability).
-
-== Example of tag:enums tags
-
-<<tag-types:example,An example>> showing a tag with attribute
-attr:type`="enum"` is given above.
-The following example is for non-enumerated tokens.
-
-[source,xml]
---------------------------------------
-<enums>
-    <enum value="256" name="VK_MAX_EXTENSION_NAME"/>
-    <enum value="MAX_FLOAT"  name="VK_LOD_CLAMP_NONE"/>
-</enums>
---------------------------------------
-
-When processed into a C header, and assuming all these tokens were required,
-this results in
-
-[source,c]
---------------------------------------
-#define VK_MAX_EXTENSION_NAME   256
-#define VK_LOD_CLAMP_NONE       MAX_FLOAT
---------------------------------------

-
-[[tag-enum]]
-= Enumerants (tag:enum tag)
-
-Each tag:enum tag defines a single Vulkan (or other API) token.
-
-== Attributes of tag:enum tags
-
-  * attr:value is a numeric value in the form of a legal C expression when
-    evaluated at compile time in the generated header files.
-    This is usually either a literal integer value or the name of an alias
-    for a previously defined value, though more complex expressions are
-    sometimes employed for <<compile-time-constants, compile time
-    constants>>.
-  * attr:bitpos is a literal integer bit position in a bitmask.
-    The bit position must be in the range [0,30] when used as a flag bit in
-    a `Vk*FlagBits` data type.
-    Bit positions 31 and up may be used for values that are not flag bits,
-    or for <<adding-bitflags, flag bits used with 64-bit flag types>>.
-    Exactly one of attr:value and attr:bitpos must be present in an tag:enum
-    tag.
-  * attr:name - required.
-    Enumerant name, a legal C preprocessor token name.
-  * attr:api - optional <<schema:apiname, API names>> for which this
-    definition is specialized, so that different APIs may have different
-    values for the same token.
-    This definition is only used if the requested API name matches the
-    attribute.
-    May be used to address subtle incompatibilities.
-  * attr:type - may be used only when attr:value is specified.
-    In this case, attr:type is optional except when defining a
-    <<compile-time-constants, compile time constant>>, in which case it is
-    required when using some output generator paths.
-    If present the attribute must be a C scalar type corresponding to the
-    type of attr:value, although only `uint32_t`, `uint64_t`, and `float`
-    are currently meaningful.
-    attr:type is used by some output generators to generate constant
-    declarations, although the default behavior is to use C `#define` for
-    compile-time constants.
-  * attr:alias - optional.
-    Name of another enumerant this is an alias of, used where token names
-    have been changed as a result of profile changes or for consistency
-    purposes.
-    An enumerant alias is simply a different attr:name for the exact same
-    attr:value or attr:bitpos.
-  * attr:protect - optional.
-    An additional preprocessor token used to protect an enum definition.
-
-[NOTE]
-.Note
-====
-In older versions of the schema, attr:type was described as allowing only
-the C integer suffix types `u` and `ull`, which is inconsistent with the
-current definition.
-However, attr:type was not actually used in the registry processing scripts
-or `vk.xml` at the time the current definition was introduced, so this is
-expected to be a benign change.

-== Contents of tag:enum tags
-
-tag:enum tags have no allowed contents.
-All information is contained in the attributes.
-
-
-[[tag-unused]]
-= Unused Enumerants (tag:unused tag)
-
-Each tag:unused tag defines a range of enumerants which is allocated, but
-not yet assigned to specific enums.
-This just tracks the unused values for the Registrar's use, and is not used
-for header generation.
-
-[NOTE]
-.Note
-====
-tag:unused tags could be generated and inserted automatically, which would
-be a good way to avoid the attributes becoming out of date.
-However, they are rarely used in the Vulkan XML schema, unlike the OpenGL
-XML schema it was based on.
-====
-
-== Attributes of tag:unused tags
-
-  * attr:start - required, attr:end - optional.
-    Integers defining the start and end of an unused range of enumerants.
-    attr:start must be {leq} attr:end.
-    If attr:end is not present, then attr:start defines a single unused
-    enumerant.
-    This range should not exceed the range reserved by the surrounding
-    tag:enums tag.
-  * attr:vendor - optional.
-    String describing the vendor or purposes to whom a reserved range of
-    enumerants is allocated.
-    Usually identical to the attr:vendor attribute of the surrounding
-    attr:enums block.
-  * attr:comment - optional.
-    Arbitrary string (unused).
-
-== Contents of tag:unused tags
-
-None.
-
-
-[[tag-commands]]
-= Command Blocks (tag:commands tag)
-
-The tag:commands tag contains definitions of each of the functions
-(commands) used in the API.
-
-== Attributes of tag:commands tags
-
-  * attr:comment - optional.
-    Arbitrary string (unused).
-
-== Contents of tag:commands tags
-
-Each tag:commands block contains zero or more tag:command tags, in arbitrary
-order (although they are typically ordered by sorting on the command name,
-to improve human readability).
-
-
-[[tag-command]]
-= Commands (tag:command tag)
-
-The tag:command tag contains a structured definition of a single API command
-(function).
-
-== Attributes of tag:command tags
-
-There are two ways to define a command.
-The first uses a set of attributes to the tag:command tag defining
-properties of the command used for constructing automatic validation rules,
-and the contents of the tag:command tag define the name, signature, and
-parameters of the command.
-In this case the allowed attributes include:
-
-  * attr:queues - optional.
-    A string identifying the command queues this command can be placed on.
-    The format of the string is one or more of the terms `"compute"`,
-    `"transfer"`, and `"graphics"`, with multiple terms separated by commas
-    (`","`).
-  * attr:successcodes - optional.
-    A string describing possible successful return codes from the command,
-    as a comma-separated list of Vulkan result code names.
-  * attr:errorcodes - optional.
-    A string describing possible error return codes from the command, as a
-    comma-separated list of Vulkan result code names.
-  * attr:renderpass - optional.
-    A string identifying whether the command can be issued only inside a
-    render pass (`"inside"`), only outside a render pass (`"outside"`), or
-    both (`"both"`).
-  * attr:cmdbufferlevel - optional.
-    A string identifying the command buffer levels that this command can be
-    called by.
-    The format of the string is one or more of the terms `"primary"` and
-    `"secondary"`, with multiple terms separated by commas (`","`).
-  * attr:comment - optional.
-    Arbitrary string (unused).
-
-The second way of defining a command is as an alias of another command.
-For example when an extension is promoted from extension to core status, the
-commands defined by that extensions become aliases of the corresponding new
-core commands.
-In this case, only two attributes are allowed:
-
-  * attr:name - required.
-    A string naming the command defined by the tag.
-  * attr:alias - required.
-    A string naming the command that attr:name is an alias of.
-    The string must be the same as the attr:name value of another
-    tag:command defining another command.
-
-== Contents of tag:command tags
-
-  * tag:proto is required and must be the first element.
-    It is a tag defining the C function prototype of a command as described
-    below, up to the function name and return type but not including
-    function parameters.
-  * tag:param elements for each command parameter follow, defining its name
-    and type, as described below.
-    If a command takes no arguments, it has no tag:param tags.
-
-Following these elements, the remaining elements in a tag:command tag are
-optional and may be in any order:
-
-  * tag:alias - optional.
-    Has no attributes and contains a string which is the name of another
-    command this command is an alias of, used when promoting a function from
-    vendor to Khronos extension or Khronos extension to core API status.
-    A command alias describes the case where there are two function names
-    which implement the same behavior.
-  * tag:description - optional.
-    Unused text.
-  * tag:implicitexternsyncparams - optional.
-    Contains a list of tag:param tags, each containing asciidoc source text
-    describing an object which is not a parameter of the command but is
-    related to one, and which also <<tag-command:param:attr,requires
-    external synchronization>>.
-    The text is intended to be incorporated into the API specification.
-
-[NOTE]
-.Note
-====
-Versions of the registry documentation prior to 1.1.93 asserted that command
-aliases "`resolve to the _same_ entry point in the underlying layer stack.`"
-Whilst this may be true on many implementations, it is not required - each
-command alias must be queried separately through flink:vkGetInstanceProcAddr
-or flink:vkGetDeviceProcAddr.

-[[tag-command:proto]]
-== Command prototype (tag:proto tags)
-
-The tag:proto tag defines the return type and name of a command.
-
-=== Attributes of tag:proto tags
-
-None.
-
-// attr:group - group name, an arbitrary string.
-//
-// If the group name is defined, it may be interpreted as described in
-// <<tag-group:meaning>>.
-
-=== Contents of tag:proto tags
-
-The text elements of a tag:proto tag, with all other tags removed, is legal
-C code describing the return type and name of a command.
-In addition to text, it may contain two semantic tags:
-
-  * The tag:type tag is optional, and contains text which is a valid type
-    name found in a tag:type tag.
-    It indicates that this type must be previously defined for the
-    definition of the command to succeed.
-    Builtin C types, and any derived types which are expected to be found in
-    other header files, should not be wrapped in tag:type tags.
-  * The tag:name tag is required, and contains the command name being
-    described.
-
-
-[[tag-command:param]]
-== Command parameter (tag:param tags)
-
-The tag:param tag defines the type and name of a parameter.
-Its contents are very similar to the tag:member tag used to define struct
-and union members.
-
-
-[[tag-command:param:attr]]
-=== Attributes of tag:param tags
-
-  * attr:len - if the param is an array, len may be one or more of the
-    following things, separated by commas (one for each array indirection):
-    another param of that command; `"null-terminated"` for a string; `"1"`
-    to indicate it is just a pointer (used for nested pointers); or an
-    equation in math markup for incorporation in the specification (a LaTeX
-    math expression delimited by `latexmath:[` and `]`.
-    The only variables in the equation should be the names of this or other
-    parameters.
-  * attr:altlen - if the attr:len attribute is specified, and contains a
-    `latexmath:` equation, this attribute should be specified with an
-    equivalent equation using only C builtin operators, C math library
-    function names, and variables as allowed for attr:len.
-    It must be a valid C99 expression whose result is equal to attr:len for
-    all possible inputs.
-    It is a comma separated list that has size equal to only the `latexmath`
-    item count in attr:len list.
-    This attribute is intended to support consumers of the XML who need to
-    generate validation code from the allowed length.
-  * attr:optional - optional.
-    A value of `"true"` or `"false"` determines whether this parameter can
-    be omitted by providing `NULL` (for pointers), `VK_NULL_HANDLE` (for
-    handles), or 0 (for other scalar types).
-    If the parameter is a pointer to one of those types, multiple values may
-    be provided, separated by commas - one for each pointer indirection.
-    If not present, the value is assumed to be `"false"` (the parameter must
-    not be omitted).
-+
---
-[NOTE]
-.Note
-====
-While the attr:optional attribute can be used for scalar types such as
-integers, it does not affect the output generators included with the Vulkan
-Specification.
-In this case, the attribute serves only as an indicator to human readers of
-the XML.
-====
---
-  * attr:selector - optional.
-    If the parameter is a union, attr:selector identifies another parameter
-    of the command that is used to select which of that union's members are
-    valid.
-  * attr:noautovalidity - prevents automatic validity language being
-    generated for the tagged item.
-    Only suppresses item-specific validity - parenting issues etc.
-    are still captured.
-  * attr:externsync - optional.
-    A value of `"true"` indicates that this parameter (e.g. the object a
-    handle refers to, or the contents of an array a pointer refers to) is
-    modified by the command, and is not protected against modification in
-    multiple app threads.
-    If only certain members of an object or elements of an array are
-    modified, multiple strings may be provided, separated by commas.
-    Each string describes a member which is modified.
-    For example, the `vkQueueSubmit` command includes attr:externsync
-    attributes for the `pSubmits` array indicating that only specific
-    members of each element of the array are modified:
-+
---
-[source,xml]
---------------------------------------
-<param len="submitCount" externsync="pSubmits[].pWaitSemaphores[],pSubmits[].pSignalSemaphores[]">const <type>VkSubmitInfo</type>* <name>pSubmits</name></param>
---------------------------------------
-
-Parameters which do not have an attr:externsync attribute are assumed to not
-require external synchronization.
---
-  * attr:objecttype - only applicable for parameters which are `uint64_t`
-    values representing a Vulkan obejct handle.
-    Specifies the name of another parameter which must be a `VkObjectType`
-    or `VkDebugReportObjectTypeEXT` value specifying the type of object the
-    handle refers to.
-
-=== Contents of tag:param tags
-
-The text elements of a tag:param tag, with all other tags removed, is legal
-C code describing the type and name of a function parameter.
-In addition it may contain two semantic tags:
-
-  * The tag:type tag is optional, and contains text which is a valid type
-    name found in tag:type tag, and indicates that this type must be
-    previously defined for the definition of the command to succeed.
-    Builtin C types, and any derived types which are expected to be found in
-    other header files, should not be wrapped in tag:type tags.
-  * The tag:name tag is required, and contains the parameter name being
-    described.

-[[tag-feature]]
-= API Features and Versions (tag:feature tag)
-
-API features are described in individual tag:feature tags.
-A feature is the set of interfaces (enumerants and commands) defined by a
-particular API and version, such as Vulkan 1.0, and includes all profiles of
-that API and version.
-
-== Attributes of tag:feature tags
-
-  * attr:api - required <<schema:apiname, API names>> this feature is
-    defined for, such as `vulkan`.
-  * attr:name - required.
-    Version name, used as the C preprocessor token under which the version's
-    interfaces are protected against multiple inclusion.
-    Example: `"VK_VERSION_1_0"`.
-  * attr:number - required.
-    Feature version number, usually a string interpreted as
-    `majorNumber.minorNumber`.
-    Example: `4.2`.
-  * attr:sortorder - optional.
-    A decimal number which specifies an order relative to other tag:feature
-    tags when calling output generators.
-    Defaults to `0`.
-    Rarely used, for when ordering by attr:name is insufficient.
-  * attr:protect - optional.
-    An additional preprocessor token used to protect a feature definition.
-    Usually another feature or extension attr:name.
-    Rarely used, for odd circumstances where the definition of a feature or
-    extension requires another to be defined first.
-  * attr:comment - optional.
-    Arbitrary string (unused).
-
-[NOTE]
-.Note
-====
-The attr:name attribute used for Vulkan core versions, such as
-`"VK_VERSION_1_0"`, is not an API construct.
-It is used only as a preprocessor guard in the headers, and an asciidoctor
-conditional in the specification sources.
-The similar `"VK_API_VERSION_1_0"` symbols are part of the API and their
-values are packed integers containing Vulkan core version numbers.
-====
-
-== Contents of tag:feature tags
-
-Zero or more <<tag-required,tag:require and tag:remove tags>>, in arbitrary
-order.
-Each tag describes a set of interfaces that is respectively required for, or
-removed from, this feature, as described below.

-[[tag-extensions]]
-= Extension Blocks (tag:extensions tag)
-
-The tag:extensions tag contains definitions of each of the extenions which
-are defined for the API.
-
-== Attributes of tag:extensions tags
-
-  * attr:comment - optional.
-    Arbitrary string (unused).
-
-== Contents of tag:extensions tags
-
-Each tag:extensions block contains zero or more tag:extension tags, each
-describing an API extension, in arbitrary order (although they are typically
-ordered by sorting on the extension name, to improve human readability).
-
-
-[[tag-extension]]
-= API Extensions (tag:extension tag)
-
-API extensions are described in individual tag:extension tags.
-An extension is the set of interfaces defined by a particular API extension
-specification, such as `ARB_multitexture`.
-tag:extension is similar to tag:feature, but instead of having attr:version
-and attr:profile attributes, instead has a attr:supported attribute, which
-describes the set of API names which the extension can potentially be
-implemented against.
-
-== Attributes of tag:extension tags
-
-  * attr:name - required.
-    Extension name, following the conventions in the Vulkan Specification.
-    Example: `name="VK_VERSION_1_0"`.
-  * attr:number - required.
-    A decimal number which is the registered, unique extension number for
-    attr:name.
-  * attr:sortorder - optional.
-    A decimal number which specifies an order relative to other
-    tag:extension tags when calling output generators.
-    Defaults to `0`.
-    Rarely used, for when ordering by attr:number is insufficient.
-  * attr:author - optional.
-    The author name, such as a full company name.
-    If not present, this can be taken from the corresponding tag:tag
-    attribute.
-    However, `EXT` and other multi-vendor extensions may not have a
-    well-defined author or contact in the tag.
-    This attribute is not used in processing the XML.
-    It is just metadata, mostly used to track the original author of an
-    extension (which may have since been promoted to use a different author
-    ID).
-  * attr:contact - optional.
-    The contact who registered or is currently responsible for extensions
-    and layers using the tag, including sufficient contact information to
-    reach the contact such as individual name together with Github username
-    (`@username`), Khronos internal Gitlab username (`gitlab:@username`) if
-    no public Github contact is available, or other contact information.
-    If not present, this can be taken from the corresponding tag:tag
-    attribute just like attr:author.
-  * attr:type - required if the attr:supported attribute is not
-    `'disabled'`.
-    Must be either `'device'` or `'instance'`, if present.
-  * attr:requires - optional.
-    Comma-separated list of extension names this extension requires to be
-    supported.
-    Extensions whose attr:type is `'instance'` must not require extensions
-    whose attr:type is `'device'`.
-  * attr:requiresCore - optional.
-    Core version of Vulkan required by the extension, e.g. "1.1".
-    Defaults to "1.0".
-  * attr:protect - optional.
-    An additional preprocessor token used to protect an extension
-    definition.
-    Usually another feature or extension attr:name.
-    Rarely used, for odd circumstances where the definition of an extension
-    requires another extension or a header file to be defined first.
-  * attr:platform - optional.
-    Indicates that the extension is specific to the platform identified by
-    the attribute value, and should be emitted conditional on that platform
-    being available, in a platform-specific header, etc.
-    The attribute value must be the same as one of the tag:platform tag:name
-    attribute values.
-  * attr:supported - required <<schema:apiname, API names>> this extension
-    is defined for.
-    When the extension tag is just reserving an extension number, use
-    `supported="disabled"` to indicate this extension should never be
-    processed.
-    Interfaces defined in a `disabled` extension block are tentative at best
-    and must: not be generated or otherwise used by scripts processing the
-    XML.
-    The only exception to this rule is for scripts used solely for
-    reserving, or checking for reserved bitflag values.
-  * attr:promotedto - optional.
-    A Vulkan version or a name of an extension that this extension was
-    _promoted_ to.
-    E.g. `"VK_VERSION_1_1"`, or `"VK_KHR_draw_indirect_count"`.
-  * attr:deprecatedby - optional.
-    A Vulkan version or a name of an extension that _deprecates_ this
-    extension.
-    It may be an empty string.
-    E.g. `"VK_VERSION_1_1"`, or `"VK_EXT_debug_utils"`, or `""`.
-  * attr:obsoletedby - optional.
-    A Vulkan version or a name of an extension that _obsoletes_ this
-    extension.
-    It may be an empty string.
-    E.g. `"VK_VERSION_1_1"`, or `"VK_KHR_maintenance1"`, or `""`.
-  * attr:provisional - optional.
-    'true' if this extension is released provisionally.
-  * attr:specialuse - optional.
-    If present, must contain one or more tokens separated by commas,
-    indicating a special purpose of the extension.
-    Tokens may include:
-  ** 'cadsupport' - for support of CAD software.
-  ** 'd3demulation' - for support of Direct3D emulation layers or libraries,
-     or applications porting from Direct3D.
-  ** 'debugging' - for debugging an application.
-  ** 'devtools' - for support of developer tools, such as capture-replay
-     libraries.
-  ** 'glemulation' - for support of OpenGL and/or OpenGL ES emulation layers
-     or libraries, or applications porting from those APIs.
-  * attr:comment - optional.
-    Arbitrary string (unused).
-
-
-[NOTE]
-.Note
-====
-The attr:requires attribute is used to specify other extensions that *must*
-be enabled for an extension to be enabled.
-
-In some cases, an extension may include functionality which is only defined
-*if* another extension is enabled.
-Such functionality should be specified within a tag:require, using the
-attr:extension attribute to specify that extension.
-====
-
-== Contents of tag:extension tags
-
-Zero or more <<tag-required,tag:require and tag:remove tags>>, in arbitrary
-order.
-Each tag describes a set of interfaces that is respectively required for, or

-[[tag-required]]
-= Required and Removed Interfaces (tag:require and tag:remove tags)
-
-A tag:require block defines a set of interfaces (types, enumerants and
-commands) 'required' by a tag:feature or tag:extension.
-A tag:remove block defines a set of interfaces 'removed' by a tag:feature.
-This is primarily for future profiles of an API which may choose to
-deprecate and/or remove some interfaces.
-Extensions should never remove interfaces, although this usage is allowed by
-the schema).
-Except for the tag name and behavior, the contents of tag:require and
-tag:remove tags are identical.
-
-== Attributes of tag:require and tag:remove tags
-
-  * attr:profile - optional.
-    String name of an API profile.
-    Interfaces in the tag are only required (or removed) if the specified
-    profile is being generated.
-    If not specified, interfaces are required (or removed) for all API
-    profiles.
-  * attr:comment - optional.
-    Arbitrary string (unused).
-  * attr:api - optional <<schema:apiname, API names>> requiring or removing
-    these interfaces.
-    Interfaces in the tag are only required (or removed) if the requested
-    API name matches the attribute.
-    If not specified, interfaces are required (or removed) for all APIs.
-
-[NOTE]
-.Note
-====
-The attr:api attribute is only supported inside tag:extension tags, since
-tag:feature tags already define a specific API.
-====
-
-== Attributes of tag:require tags
-
-These attribues are allowed only for a tag:require tag.
-
-  * attr:extension - optional, and only for tag:require tags.
-    String containing an API extension name.
-    Interfaces in the tag are only required if the string matches the
-    attr:name of an tag:extension tag, and that extension is enabled.
-  * attr:feature - optional, and only for tag:require tags.
-    String containing an API feature name.
-    Interfaces in the tag are only required if the string matches the
-    attr:name of a tag:feature tag, and that feature is enabled.
-
-[NOTE]
-.Note
-====
-The attr:extension attribute currently does not affect output generators in
-any way, and is simply metadata.
-This will be addressed as we better define different types of dependencies
-between extensions.
-====
-
-== Contents of tag:require and tag:remove tags
-
-Zero or more of the following tags, in any order:
-
-=== Comment Tags
-
-<<tag-comment, tag:comment>> (as described above).
-
-=== Command Tags
-
-tag:command specifies an required (or removed) command defined in a
-tag:commands block.
-The tag has no content, but contains attributes:
-
-  * attr:name - required.
-    Name of the command.
-  * attr:comment - optional.
-    Arbitrary string (unused).
-
-=== Enum tags
-
-tag:enum specifies an required (or removed) enumerant defined in a tag:enums
-block.
-All forms of this tag support the following attributes:
-
-  * attr:name - required.
-    Name of the enumerant.
-  * attr:comment - optional.
-    Arbitrary string (unused).
-  * attr:api - optional <<schema:apiname, API names>> for which this
-    definition is specialized, so that different APIs may have different
-    values for the same token.
-    This definition is only used if the requested API name matches the
-    attribute.
-    May be used to address subtle incompatibilities.
-
-There are two forms of tag:enum tags:
-
-_Reference enums_ simply pull in the definition of an enumerant given in a
-separate tag:enums block.
-No attributes other than attr:name and attr:comment are supported for them.
-tag:enum tags appearing inside tag:remove tags should always be reference
-enums.
-Reference enums may also be used inside tag:require tags, if the
-corresponding value is defined in a tag:enums block.
-This is typically used for constants not part of an enumerated type.
-
-_Extension enums_ define the value of an enumerant inline in an tag:feature
-or tag:extensions block.
-Typically these are used to add additional values specified by an extension
-or core feature to an existing enumerated type.
-There are a variety of attributes which are used to specify the value of the
-enumerant:
-
-  * attr:value and attr:type - define a constant value in the same fashion
-    as an tag:enum tag in an <<tag-enum,tag:enums>> block.
-  * attr:bitpos - define a constant bitmask value in the same fashion as an
-    <<tag-enum,tag:enum>> tag in an tag:enums block.
-    attr:bitpos is a literal integer bit position in a bitmask.
-    The same value and usage constraints apply to this bit position as are
-    applied to the <<tag-enum, attr:bitpos attribute of an tag:enum tag.
-  * attr:extends - the name of a separately defined enumerated type (e.g. a
-    tag:type tag with attr:category``="enum"``) to which the extension
-    enumerant is added.
-    The enumerated type is required to complete the definition of the
-    enumerant, in the same fashion as the attr:requires attribute of a
-    tag:type tag.
-    If not present, the enumerant is treated as a global constant value.
-  * attr:extnumber - an extension number.
-    The extension number in turn specifies the starting value of a block
-    (range) of values reserved for enumerants defined by or associated with
-    the corresponding tag:extension tag with the same attr:number.
-    This is used when an extension or core feature needs to extend an
-    enumerated type in a block defined by a different extension.
-  * Attribute attr:offset - the offset within an extension block.
-    If attr:extnumber is not present, the extension number defining that
-    block is given by the attr:number attribute of the surrounding
-    tag:extension tag.
-    The actual numeric value of the enumerant is computed as defined in the
-    "`Layers and Extensions`" appendix of the Vulkan Specification.
-  * Attribute attr:dir - if present, the calculated enumerant value will be
-    negative, instead of positive.
-    Negative enumerant values are normally used only for Vulkan error codes.
-    The attribute value must be specified as `dir="-"`.
-  * attr:alias - the name of another enumerant this is an alias of.
-    An enumerant alias is simply a different name for the same enumerant
-    value.
-    This is typically used when promoting an enumerant defined by an
-    extension to a new core version of the API.
-    The old extension enumerant is still defined, but as an alias of the new
-    core enumerant.
-    It may also be used when token names have been changed as a result of
-    profile changes, or for consistency purposes.
-  * attr:protect - define a preprocessor protection symbol for the enum in
-    the same fashion as a tag:enum tag in an <<tag-enum,tag:enums>> block.
-
-Not all combinations of attributes are either meaningful or supported.
-The attr:protect attribute may always be present.
-For other attributes, the allowed combinations are:

-tag:extension.
-Otherwise, the tag:enum tag may also be within a tag:feature.
-

-constant.
-Otherwise, the value is added to the specified enumeration.
-
-Examples of <<tag-required-examples,various types of extension enumerants>>

-=== Type tags
-
-tag:type specifies a required (or removed) type defined in a tag:types
-block.
-Most types are picked up implicitly by using the tag:type tags of commands,
-but in a few cases, additional types need to be specified explicitly.
-It is unlikely that a type would ever be removed, although this usage is
-allowed by the schema.
-The tag has no content, but contains elements:
-
-  * attr:name - required.
-    Name of the type.
-  * attr:comment - optional.
-    Arbitrary string (unused).

-
-For people new to the Registry, it will not be immediately obvious how to
-make changes.
-This section includes some tips and examples that will help you make changes
-to the Vulkan headers by changing the Registry XML description.
-
-First, follow the steps described to <<starting,get the Vulkan Github
-repository>> containing the registry and assemble the tools necessary to
-work with the XML registry.
-Once you are able to regenerate the Vulkan headers from `vk.xml`, you can
-start making changes.
-
-
-== General Strategy
-
-If you are _adding_ to the API, perform the following steps to _create_ the
-description of that API element:
-
-  * For each type, enum group, compile time constant, and command being
-    added, create appropriate new tag:type, tag:enums, tag:enum, or
-    tag:command tags defining the interface in question.
-  * Make sure that all added types and commands appropriately tag their
-    dependencies on other types by adding nested tag:type tags.
-  * Make sure that each new tag defines the name of the corresponding type,
-    enum group, constant, or command, and that structure/union types and
-    commands tag the types and names of all their members and parameters.
-    This is essential for the automatic dependency process to work.
-
-If you are _modifying_ existing APIs, just make appropriate changes in the
-existing tags.
-
-Once the definition is added, proceed to the next section to create
-dependencies on the changed feature.
-
-
-== API Feature Dependencies
-
-When you add new API elements, they will not result in corresponding changes
-in the generated header unless they are _required_ by the interface being
-generated.
-This makes it possible to include different API versions and extensions in a
-single registry and pull them out as needed.
-So you must introduce a dependency on new features in the corresponding
-tag:feature tag.
-
-Initially, the only API feature is Vulkan 1.0, so there is only one
-tag:feature tag in `vk.xml`.
-You can find it by searching for the following block of `vk.xml`:
-
-[source,xml]
---------------------------------------
-<comment>
-<feature api="vulkan" name="VK_VERSION_1_0" number="1.0"
-         comment="Vulkan core API interface definitions">
---------------------------------------
-
-Inside the tag:feature tag are nested multiple tag:require tags.
-These are just being used as a logical grouping mechanism for related parts
-of Vulkan 1.0 at present, though they may have more meaningful roles in the
-future if different API profiles are defined.
-
-
-=== API Feature Walkthrough
-
-This section walks through the first few required API features in the
-`vk.xml` tag:feature tag, showing how each requirement pulls in type, token,
-and command definitions and turns those into definitions in the C header
-file `vulkan_core.h`.
-
-Consider the first few lines of the tag:feature:
-
-[source,xml]
---------------------------------------
-<require comment="Header boilerplate">
-    <type name="vk_platform"/>
-</require>
-<require comment="API constants">
-    <enum name="VK_MAX_PHYSICAL_DEVICE_NAME"/>
-    <enum name="VK_MAX_EXTENSION_NAME"/>
-    ...
-</require>
-<require comment="Device initialization">
-    <command name="vkCreateInstance"/>
-    ...
---------------------------------------
-
-The first tag:require block says to require a type named `vk_platform`.
-If you look at the beginning of the tag:types section, there is a
-corresponding definition section:
-
-[source,xml]
---------------------------------------
-<type name="vk_platform">#include "vk_platform.h"
-#define VK_MAKE_VERSION(major, minor, patch) \
-    ((major &lt;&lt; 22) | (minor &lt;&lt; 12) | patch)
-    ...
---------------------------------------
-
-This section is invoked by the requirement and emits a bunch of boilerplate
-C code.
-The explicit dependency is not strictly required since `vk_platform` will be
-required by many other types, but placing it first causes this to appear
-first in the output file.
-
-Note that `vk_platform` does not correspond to an actual C type, but instead
-to a collection of freeform preprocessor includes and macros and comments.
-Most other tag:type tags do define a specific type and are much simpler, but
-this approach can be used to inject arbitrary C into the Vulkan headers
-*when there is no other way*.
-In general inserting arbitrary C is strongly discouraged outside of specific
-special cases like this.
-
-The next tag:require block pulls in some compile time constants.
-These correspond to the definitions found in the first tag:enums section of
-`vk.xml`:
-
-[source,xml]
---------------------------------------
-<enums name="API Constants"
-       comment="Vulkan hardcoded constants - not an enumerated type, part of the header boilerplate">
-    <enum value="256"        name="VK_MAX_PHYSICAL_DEVICE_NAME"/>
-    <enum value="256"        name="VK_MAX_EXTENSION_NAME"/>
-    ...
---------------------------------------
-
-The third tag:require block starts pulling in some Vulkan commands.
-The first command corresponds to the following definition found in the
-tag:commands section of `vk.xml`:
-
-[source,xml]
---------------------------------------
-<commands>
-    <command>
-        <proto><type>VkResult</type> <name>vkCreateInstance</name></proto>
-        <param>const <type>VkInstanceCreateInfo</type>* <name>pCreateInfo</name></param>
-        <param><type>VkInstance</type>* <name>pInstance</name></param>
-    </command>
-    ...
---------------------------------------
-
-In turn, the tag:command tag requires the tag:types `VkResult`,
-`VkInstanceCreateInfo`, and `VkInstance` as part of its definition.
-The definitions of these types are determined as follows:
-
-For `VkResult`, the corresponding required tag:type is:
-
-[source,xml]
---------------------------------------
-<type name="VkResult" category="enum"/>
---------------------------------------
-
-Since this is an enumeration type, it simply links to an tag:enums tag with
-the same name:
-
-[source,xml]
---------------------------------------
-<enums name="VkResult" type="enum" comment="API result codes">
-        <comment>Return codes (positive values)</comment>
-    <enum value="0"     name="VK_SUCCESS"/>
-    <enum value="1"     name="VK_UNSUPPORTED"/>
-    <enum value="2"     name="VK_NOT_READY"/>
-    ...
-        <comment>Error codes (negative values)</comment>
-    <enum value="-1"    name="VK_ERROR_OUT_OF_HOST_MEMORY" comment="A host memory allocation has failed"/>
-    ...
---------------------------------------
-
-For `VkInstanceCreateInfo`, the required tag:type is:
-
-[source,xml]
---------------------------------------
-<type category="struct" name="VkInstanceCreateInfo">
-    <member values="VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO"><type>VkStructureType</type> <name>sType</name></member>
-    <member>const void*                         <name>pNext</name></member>
-    <member>const <type>VkApplicationInfo</type>* <name>pAppInfo</name></member>
-    <member>const <type>VkAllocCallbacks</type>* <name>pAllocCb</name></member>
-    <member><type>uint32_t</type>               <name>extensionCount</name></member>
-    <member>const <type>char</type>*const*      <name>ppEnabledExtensionNames</name></member>
-</type>
---------------------------------------
-
-This is a structure type, defining a C `struct` with all the members defined
-in each tag:member tag in order.
-In addition, it requires some other types, whose definitions are located by
-name in exactly the same fashion.
-
-For the final direct dependency of the command, `VkInstance`, the required
-tag:type is:
-
-[source,xml]
---------------------------------------
-    <comment>Types which can be void pointers or class pointers, selected at compile time</comment>
-<type>VK_DEFINE_BASE_HANDLE(<name>VkObject</name>)</type>
-<type>VK_DEFINE_DISP_SUBCLASS_HANDLE(<name>VkInstance</name>, <type>VkObject</type>)</type>
---------------------------------------
-
-In this case, the type `VkInstance` is defined by a special compile time
-macro which defines it as a derived class of `VkObject` (for `C```) or a
-less typesafe definition (for C).
-This macro is not part of the type dependency analysis, just the boilerplate
-used in the header.
-
-If these are the only tag:feature dependencies in `vk.xml`, the resulting
-`vulkan_core.h` header will look like this:
-
-[source,c]

-[[compile-time-constants]]
-== How To Add A Compile Time Constant
-
-Go to the desired tag:feature or tag:extension tag.
-Add (if not present) a nested tag:require block labelled
-
-[source,xml]
---------------------------------------
-<require comment="API constants">
---------------------------------------
-
-In this block, add an (appropriately indented) tag like
-
-[source,xml]
---------------------------------------
-    <enum name="VK_THE_ANSWER"/>
---------------------------------------
-
-Then go to the tag:enums block labelled
-
-[source,xml]
---------------------------------------
-<enums comment="Misc. hardcoded constants - not an enumerated type">
---------------------------------------
-
-In this block, add a tag whose attr:name attribute matches the attr:name you
-defined above and whose attr:value attribute is the value to give the
-constant:
-
-[source,xml]
---------------------------------------
-    <enum value="42" type="uint32_t" name="VK_THE_ANSWER"/>
---------------------------------------
-
-The attr:type attribute must be present, and must have one of the allowed
-values `uint32_t`, `uint64_t`, or `float`.
-
-
-[[compile-time-constants-format]]
-== Allowed Format of Compile Time Constants
-
-The attr:value attribute must be a legal C99 constant scalar expression when
-evaluated at compilation time.
-Allowed expressions are additionally restricted to the following syntax:
-
-  * a single C decimal integer or floating-point value
-  * optionally prefixed with `~`
-  * optionally suffixed with `U`, `UL`, `ULL`, or `F`
-  * and the entire expression optionally surrounded by paired `(` and `)`.
-
-
-== How To Add A Struct or Union Type
-
-For this example, assume we want to define a type corresponding to a C
-`struct` defined as follows:
-
-[source,c]
---------------------------------------
-typedef struct {
-    VkStructureType          sType;
-    const void*              pNext;
-    const VkApplicationInfo* pAppInfo;
-    const VkAllocCallbacks*  pAllocCb;
-    uint32_t                 extensionCount;
-    const char*const*        ppEnabledExtensionNames;
-} VkInstanceCreateInfo;
---------------------------------------
-
-If `VkInstanceCreateInfo` is the type of a parameter of a command in the
-API, make sure that command's definition (see below for how to add a
-command) puts `VkInstanceCreateInfo` in nested tag:type tags where it is
-used.
-
-Otherwise, if the struct type is not used directly by a command in the API,
-nor required by a chain of type dependencies for other commands, an explicit
-tag:type dependency should be added to the tag:feature tag.
-Go to the tag:types tag and search for the nested block labelled
-
-[source,xml]
---------------------------------------
-<require comment="Types not directly used by the API. Include e.g. structs that are not parameter types of commands, but still defined by the API.">
-    ...
---------------------------------------
-
-In this block, add a tag whose attr:name attribute matches the attr:name of
-the struct type being defined:
-
-[source,xml]
---------------------------------------
-<require comment="API types not used by commands">
-    <type name="VkInstanceCreateInfo"/>
-    ...
---------------------------------------
-
-Then go to the tag:types tag and add a new tag:type tag defining the struct
-names and members, somewhere below the corresponding comment, like this:
-
-[source,xml]
---------------------------------------
-<types>
-    ...
-        <comment>Struct types</comment>
-    <type category="struct" name="VkInstanceCreateInfo">
-        <member><type>VkStructureType</type>
-                <name>sType</name></member>
-        <member>const void*
-                <name>pNext</name></member>
-        <member>const <type>VkApplicationInfo</type>*
-                <name>pAppInfo</name></member>
-        <member>const <type>VkAllocCallbacks</type>*
-                <name>pAllocCb</name></member>
-        <member><type>uint32_t</type>
-                <name>extensionCount</name></member>
-        <member>const <type>char</type>*const*
-                <name>ppEnabledExtensionNames</name></member>
-    </type>
-    ...
---------------------------------------
-
-If any of the member types are types also defined in the header, make sure
-to enclose those type names in nested tag:type tags, as shown above.
-Basic C types should not be tagged.
-
-If the type is a C `union`, rather than a `struct`, then set the value of
-the attr:category attribute to `"union"` instead of `"struct"`.
-
-
-== How To Add An Enumerated Type
-
-For this example, assume we want to define a type corresponding to a C
-`enum` defined as follows:
-
-[source,c]
---------------------------------------
-typedef enum {
-    VK_DEVICE_CREATE_VALIDATION_BIT = 0x00000001,
-    VK_DEVICE_CREATE_MULTI_DEVICE_IQ_MATCH_BIT = 0x00000002;
-} VkDeviceCreateFlagBits.
---------------------------------------
-
-If `VkDeviceCreateFlagBits` is the type of a parameter to a command in the
-API, or of a member in a structure or union, make sure that command
-parameter or struct member's definition puts `VkDeviceCreateFlagBits` in
-nested tag:type tags where it is used.
-
-Otherwise, if the enumerated type is not used directly by a command in the
-API, nor required by a chain of type dependencies for commands and structs,
-an explicit tag:type dependency should be added to the tag:feature tag in
-exactly the same fashion as described above for `struct` types.
-
-Next, go to the line labelled
-
-[source,xml]
---------------------------------------
-<comment>Vulkan enumerant (token) definitions</comment>
---------------------------------------
-
-At an appropriate point below this line, add an tag:enums tag whose
-attr:name attribute matches the tag:type name `VkDeviceCreateFlagBits`, and
-whose contents correspond to the individual fields of the enumerated type:
-
-[source,xml]
---------------------------------------
-<enums name="VkDeviceCreateFlagBits" type="bitmask">
-    <enum bitpos="0" name="VK_DEVICE_CREATE_VALIDATION_BIT"/>
-    <enum bitpos="1" name="VK_DEVICE_CREATE_MULTI_DEVICE_IQ_MATCH_BIT"/>
-</enums>
---------------------------------------
-
-Several other attributes of the tag:enums tag can be set.
-In this case, the attr:type attribute is set to `"bitmask"`, indicating that
-the individual enumerants represent elements of a bitmask.
-
-The individual tag:enum tags define the enumerants, just like the definition
-for compile time constants described above.
-In this case, because the enumerants are bits in a bitmask, their values are
-specified using the attr:bitpos attribute.
-The value of this attribute must be an integer in the range [0,30]
-specifying a single bit number, and the resulting value is printed as a
-hexadecimal constant corresponding to that bit.
-
-It is also possible to specify enumerant values using the attr:value
-attribute, in which case the specified numeric value is passed through to
-the C header unchanged.

-[[adding-bitflags]]
-== How To Add Bit Flags
-
-Bit masks are defined by two types in the xml - the type of the mask itself,
-and the type of the valid flags.
-
-For this example, assume we want to define bit flags that can handle up to
-64 independent values as follows:
-
-[source,c]
---------------------------------------
-// Flag bits for VkExampleFlagBits
-typedef VkFlags64 VkExampleFlagBits;
-static const VkExampleFlagBits VK_EXAMPLE_NONE = 0;
-static const VkExampleFlagBits VK_EXAMPLE_FIRST_BIT = 0x00000001;
-static const VkExampleFlagBits VK_EXAMPLE_SECOND_BIT = 0x00000002;
-
-typedef VkFlags64 VkExampleFlags;
---------------------------------------
-
-An explicit tag:type dependency should be added to the tag:feature tag in
-exactly the same fashion as described above for `struct` types.
-
-Firstly, a definition is needed for the flags type used as a parameter to
-commands or member of functions.
-Go to the line labelled:
-
-[source,xml]
---------------------------------------
-<comment>Bitmask types</comment>
---------------------------------------
-
-At the end of the list of `VkFlags` and `VkFlags64` types, add a definition
-of the flags type like so:
-
-[source,xml]
---------------------------------------
-<type bitvalues="VkExampleFlagBits" category="bitmask">typedef <type>VkFlags64</type> <name>VkExampleFlags</name>;</type>
---------------------------------------
-
-The attr:category defines this as a `"bitmask"` type.
-The attr:bitvalues attribute identifies the `*FlagBits` entry defining the
-flag bits associated with this type.
-
-Next, go to the line labelled:
-
-[source,xml]
---------------------------------------
-<comment>Types generated from corresponding enums tags below</comment>
---------------------------------------
-
-At an appropriate point in the list of enum types after this comment, add
-the following line:
-
-[source,xml]
---------------------------------------
-<type name="VkExampleFlagBits" category="enum"/>
---------------------------------------
-
-This defines a type for the flag bits for generators that need it.
-The attr:category attribute of `"enum"` identifies that this is an
-enumerated type.
-
-Finally, go to the line labelled:
-
-[source,xml]
---------------------------------------
-<comment>Vulkan enumerant (token) definitions</comment>
---------------------------------------
-
-At the end of the list of enum definitions below this line, add an tag:enums
-tag whose attr:name attribute matches the tag:type name `VkExampleFlagBits`,
-and whose contents correspond to the individual fields of the enumerated
-type:
-
-[source,xml]
---------------------------------------
-<enums name="VkExampleFlagBits" type="bitmask" bitwidth="64">
-    <enum value="0" name="VK_EXAMPLE_NONE"/>
-    <enum bitpos="0" name="VK_EXAMPLE_FIRST_BIT"/>
-    <enum bitpos="1" name="VK_EXAMPLE_SECOND_BIT"/>
-</enums>
---------------------------------------
-
-The attr:type attribute is set to `"bitmask"`, indicating that the
-individual enumerants represent elements of a bitmask.
-The attr:bitwidth attribute is set to `"64"` indicating that this is a
-64-bit flag type.
-
-The individual tag:enum tags define the enumerants, just like the definition
-for compile time constants described above.
-In this case, a "no flags" type is defined in `VK_EXAMPLE_NONE` with the
-attr:value attribute defining it to have a hard value of 0.
-The other types have their values are specified using the attr:bitpos
-attribute, as these are actual bit flag values.
-The value of this attribute must be an integer in the range [0,63]
-specifying a single bit number, and the resulting value is printed as a
-hexadecimal constant corresponding to that bit.
-
-
-=== 32-bit Flags
-
-Bit flags can also be defined using 32-bit C enum types.
-Doing so is broadly similar to 64-bit bit flags, but with a few key
-differences.
-For this example, assume we want to define the same type as above, but
-corresponding to a C `enum` and flags type defined as follows:
-
-[source,c]
---------------------------------------
-typedef enum VkExampleFlagBits {
-    VK_EXAMPLE_NONE
-    VK_DEVICE_CREATE_VALIDATION_BIT = 0x00000001,
-    VK_DEVICE_CREATE_MULTI_DEVICE_IQ_MATCH_BIT = 0x00000002;
-} VkExampleFlagBits;
-
-typedef VkFlags VkExampleFlags;
---------------------------------------
-
-To add this to the xml, entries need to be added to the XML in the same way
-as above, but with slightly different attributes:
-
-For the flag type definition, the entry should use `VkFlags` instead of
-`VkFlags64`, and require the flag bits type, instead of specifying the
-attr:bitvalues attribute:
-
-[source,xml]
---------------------------------------
-<type requires="VkExampleFlagBits" category="bitmask">typedef <type>VkFlags</type> <name>VkExampleFlags</name>;</type>
---------------------------------------
-
-For the definition of the enumerated flag values themselves, the bitwidth
-needs to either be changed to `"32"`, or omitted entirely (which defaults to
-a bitwidth of 32) as follows:
-
-[source,xml]
---------------------------------------
-<enums name="VkExampleFlagBits" type="bitmask">
---------------------------------------
-
-Note that 32-bit bitmasks must use an integer in the range [0,30] - C enums
-are only guaranteed to support signed 32-bit integer values, and defining an
-unsigned value for the 31st bit could change the size of the enum type.
-The generator scripts will warn about values exceeding this range.
-
-
-== How to Add A Command
-
-For this example, assume we want to define the command:
-
-[source,c]
---------------------------------------
-VKAPI_ATTR VkResult VKAPI_CALL vkCreateInstance(
-    const VkInstanceCreateInfo*                 pCreateInfo,
-    VkInstance*                                 pInstance);
---------------------------------------
-
-Commands must always be explicitly required in the tag:feature tag.
-In that tag, you can use an existing tag:require block including API
-features which the new command should be grouped with, or define a new
-block.
-For this example, add a new block, and require the command by using the
-tag:command tag inside that block:
-
-[source,xml]
---------------------------------------
-<feature api="vulkan" name="VK_VERSION_1_0" number="1.0" comment="Vulkan core API interface definitions">
-    ...
-    <require comment="Device initialization">
-        <command name="vkCreateInstance"/>
-    </require>
-    ...
-</feature>
---------------------------------------
-
-The tag:require block may include a attr:comment attribute whose value is a
-descriptive comment of the contents required within that block.
-The comment is not currently used in header generation, but might be in the
-future, so use comments which are polite and meaningful to users of the
-generated header files.
-
-Then go to the tag:commands tag and add a new tag:command tag defining the
-command, preferably sorted into alphabetic order with other commands for
-ease of reading, as follows:
-
-[source,xml]
---------------------------------------
-<commands comment="Vulkan command definitions">
-    ...
-    <command>
-        <proto><type>VkResult</type>
-               <name>vkCreateInstance</name></proto>
-        <param>const <type>VkInstanceCreateInfo</type>*
-               <name>pCreateInfo</name></param>
-        <param><type>VkInstance</type>*
-               <name>pInstance</name></param>
-    </command>
-    ...
-</commands>
---------------------------------------
-
-The tag:proto tag defines the return type and function name of the command.
-The tag:param tags define the command's parameters in the order in which
-they are passed, including the parameter type and name.
-The contents are laid out in the same way as the structure tag:member tags
-described previously.
-
-
-== More Complicated API Representations
-
-The registry schema can represent a good deal of additional information, for
-example by creating multiple tag:feature tags defining different API
-versions and extensions.
-This capability is not yet relevant to Vulkan.
-Those capabilities will be documented as they are needed.
-
-
-== More Complicated Output Formats And Other Languages
-
-The registry schema is oriented towards C-language APIs.
-Types and commands are defined using syntax which is a subset of C,
-especially for structure members and command parameters.
-It would be possible to use a language-independent syntax for representing
-such information, but since we are writing a C API, any such representation
-would have to be converted into C anyway at some stage.
-
-The `vulkan.h` header is written using an _output generator_ object in the
-Python scripts.
-This output generator is specialized for C, but the design of the scripts is
-intended to support writing output generators for other languages as well as
-purposes such as documentation (e.g. generating asciidoc fragments
-corresponding to types and commands for use in the API specification and
-reference pages).
-When targeting other languages, the amount of parsing required to convert
-type declarations into other languages is small.
-However, it will probably be necessary to modify some of the boilerplate C
-text, or specialize the tags by language, to support such generators.
-
-
-== Additional Semantic Tagging
-
-The schema is being extended to support semantic tags describing various
-properties of API features, such as:
-
-  * constraints on allowed scalar values to function parameters (non-`NULL`,
-    normalized floating-point, etc.)
-  * length of arrays corresponding to function pointer parameters
-  * miscellaneous properties of commands such as whether the application or
-    system is responsible for threadsafe use; which queues they may be
-    issued on; whether they are aliases or otherwise related to other
-    commands; etc.
-
-These tags will be used by other tools for purposes such as helping create
-validation layers, generating serialization code, and so on.
-We would like to eventually represent everything about the API that is
-amenable to automatic processing within the registry schema.
-Please make suggestions on the Github issue tracker.
-
-
-[[general:stability]]
-== Stability of the XML Database and Schema
-
-The Vulkan XML schema is evolving in response to corresponding changes in
-the Vulkan API and ecosystem.
-Most such change will probably be confined to adding attributes to existing
-tags and properly expressing the relationships to them, and making API
-changes corresponding to accepted feature requests.
-Changes to the schema should be described in the <<changelog,change log>> of
-this document.
-Changes to the `.xml` files and Python scripts are logged in Github history.

-= Vulkan^(R)^ Specification Repository Scripts
-
-This directory contains scripts used in building the Vulkan API
-specification and related artifacts. For the most part, these scripts are
-invoked from the top-level directory or from the API Registry in
-../xml to build generated components of the specification.
-
-Scripts in this directory include:
-
-  * `genvk.py` - Python script to generate Vulkan headers and some other
-    targets, using the generators described below.
-  * `reg.py` - Python tools to read a registry XML file and call into
-    generators to create headers and other types of output.
-  * `conventions.py`, `vkconventions.py` - API-specific parameters and
-    formatting / style conventions used by generators.
-  * `generator.py` - output generator base class.
-  ** `cgenerator.py` - C header output generator.
-  ** `docgenerator.py` - Asciidoc interface language include generator.
-  ** `extensionmetadocgenerator.py` - Generator for Asciidoc extension
-     descriptions in spec appendices.
-  ** `hostsyncgenerator.py` - Asciidoc host sync table generator.
-  ** `pygenerator.py` - Generates python encoding of the API description.
-  ** `validitygenerator.py` - Asciidoc validity language generator.
-
-  * `check_spec_links.py` - validates a variety of markup and content in the
-    Asciidoctor specification source.
-  * `make_ext_dependency.py` - generate extension dependencies in Bash and
-    Python form for use when building the specification.
-  * `genRelease`, `genspec.py` - build HTML and PDF Specifications with a
-    variety of options to control target directories, extensions included
-    while building, etc.
-  * `genRef.py`, `reflib.py` - extract API reference pages from specification
-    source into single-page source documents.
-  * `indexExt.py` - generate HTML index of all extensions for inclusion into
-    the Vulkan registry index page.
-  * `reflow.py`, `reflow_count.py` - reflow specification source text to follow
-    style guidelines, and insert Valid Usage statements where they're
-    needed.
-  * `test_check_spec_links.py`, `test_check_spec_links_api_specific.py`,
-    `test_entity_db.py` - these are from another Khronos WG repository and
-    are unused by Vulkan at present.
-
-  * `compImages.sh` - compare images in two branches.
-  * `htmldiff/htmldiff` - HTML diff script (see below).
-  * `Retired/` - contains obsolete, unused, or single-purpose scripts. Not
-    maintained.
-
-HTML Diff Script for Vulkan
-===========================
-
-This is a first cut at a script to compare Vulkan HTML specifications. Usage
-is simply 'htmldiff file1.html file2.html > diff.html'. The script does not
-copy CSS and images required by the input specs, so it's best to generate
-the output in the same directory as one of the inputs. However, the script
-must be invoked from the directory it is located within.
-
-The scripts used require Python and Perl. Additionally, the python
-'utidylib' module and the underlying libtidy C library are required.
-On Debian Linux, it may be necessary to install the 'python-utidylib' and
-'libtidy' packages if they are not already present.
-
-The scripts are taken from the code backing the
-
-    http://services.w3.org/htmldiff
-
-website. `htmldiff` is the Python driver script. `htmldiff.pl` is the
-Perl script which generates the diff after preprocessing of the input
-HTML by `htmldiff`. `htmldiff.orig` is the original Python script from
-the website, modified to run at the command line instead of as a CGI
-script.

-** This is a simple extension loader which provides the implementations for the

-** for a single instance or a single device. Multiple instances are not yet supported.
-**
-** To use the loader add vulkan_ext.c to your solution and include <vulkan/vulkan_ext.h>.
-**
-** If your application is using a single instance, but multiple devices callParam
-**
-** vkExtInitInstance(instance);
-**
-** after initializing the instance. This way the extension loader will use the loaders
-** trampoline functions to call the correct driver for each call. This method is safe
-** if your application might use more than one device at the cost of one additional
-** indirection, the dispatch table of each dispatchable object.
-**
-** If your application uses only a single device it's better to use
-**
-** vkExtInitDevice(device);
-**
-** once the device has been initialized. This will resolve the function pointers
-** upfront and thus removes one indirection for each call into the driver. This *can*

-- 2021/5/9 [Ver 1.0.2](https://github.com/wshito/asciidoctor-chunker/releases) The toc item for the titlepage can be configured with `--titlePage` option (thanks to [@johnthad](https://github.com/johnthad)).
-- 2021/3/17 [Ver 1.0.1](https://github.com/wshito/asciidoctor-chunker/releases) The script contains shebang and can be invoked directly.  Published on [npm](https://www.npmjs.com/package/asciidoctor-chunker).  You can install via npm.  See [Installation](#installation).
-- 2021/2/27 [Ver 1.0.0 Released!](https://github.com/wshito/asciidoctor-chunker/releases)
-  - Non opinionated page navigation at the bottom of each page is available.
-  - You can insert custom css from the command line with `--css` option.
-  - If you have any custom elements inserted in the source html, they are handled in non-strict mode by setting `--no-strictMode` option.
-  - Gives warning if no relative links are available in tocs.
-  - The current page toc is highlighted and scrolled into view.
-- 2021/2/20  Ver 0.9 is released!  This is a complete re-write from the previous Lisp version.  **It is re-implemented in JavaScript!**  So it is super easy to setup with NodeJS!  The fine tuned split options are available.  Oh, and it runs a lot faster than the previous version!😊
-- 2021/2/10  Started work on the more enhanced version in `javascript` branch.  Please wait a couple of weeks.  The new version can control any depth of sections to split.  And even more, each chapter can have a different depth extraction level.   The new version is written in JavaScript so it will be a lot easier to install!
-- 2018/7/11  Locally linked files with `link` and `script` tags with relative paths are copied to the destination directory keeping the structure of the relative path.  So the custom CSS and script files should be properly copied by `asciidoctor-chunker`.
-
-## What it does
-
-Asciidoctor-Chunker generates chunked HTML from a single HTML generated by Asciidoctor.
-
-1. Splits part preambles and chapters (or any depth of section level) into separate files. Each chapter can be configured to have a different depth for extractions.
-1. Extracts css inside the style element into a separate file so the browser can cache and share it among all the pages.
-1. Places footnotes in the file they belong to.  This also means that the multiply referred footnotes are placed in every referrer's files and sets the link back to the referrer's id within the page.
-1. Re-writes the relative links in order to point to the appropriate chunked files.
-1. Copies the local images and linked files (with `link`, `script` and `img` tags) whose paths are relative, to the directory relative to the chunked html output.  Files are only copied if they are new or modified compared to the previously copied one.
-1. Adds a titlepage link in the toc and page navigation at the bottom of each page.
-1. Adds non-opinionated page navigation.
-1. Highlights the current page toc items and they get scrolled into the viewport.
-
-Here is [the sample output](http://www.seinan-gu.ac.jp/~shito/asciidoctor/html_chunk/index.html) created from the [Asciidoctor User Manual](https://asciidoctor.org/docs/user-manual/).  The footer on the sample page is added by setting the asciidoctor attribute and is not added by asciidoctor-chunker.
-
-
-## Installation
-
-Asciidoctor-Chunker is written in JavaScript and runs with NodeJS.
-
-1. Install [Node.js](https://nodejs.org/), the JavaScript runtime.  This will install `npm`, the package manager CLI for Node.js.
-1. If you want to install globally, invoke the following;
-   ```
-   npm install -g asciidoctor-chunker
-   ```
-   You can install locally under the current directory as;
-   ```
-   npm install asciidoctor-chunker
-   ```
-1. Or alternatively you can download the pre-built program from the [release](https://github.com/wshito/asciidoctor-chunker/releases).
-
-## Usage
-
-If you installed globally:
-   ```
-   asiidoctor-chunker [single-html-file] -o [output-directory]
-   ```
-If you installed locally invoke the following under the directory you installed:
-   ```
-   npx asciidoctor-chunker [single-html-file] -o [output-directory]
-   ```
-If you installed the prebuild program simply run the script as:
-   ```
-   ./asciidoctor-chunker.js [single-html-file] -o [output-directory]
-   ```
-`[single-html-file]` is the single HTML file generated by [Asciidoctor](https://asciidoctor.org) from the book doctype.  If the output directory is not specified, the default is `html_chunks` under the current directory.
-
-More discription of usage is available with `--help` option.
-
-## How to Configure the Depth of Extraction
-
-You can list the multiple settings by connecting each specifier with a comma.  Each specifier is consisted of either a single number or a collon separated with two numbers.
-
-The single number sets the default level of extraction.  Number 1 is the application's default and it extracts the chapter level.  Number 2 for section extraction, 3 for subsection, and so on to 6 which is the maximum section level of Asciidoctor.
-
-The list of collon separated numbers, `chap:level`, can change the extraction depth for specific chapters, so `3:2` means chapter 3 is extracted down to 2 levels (ie. section level).  You can use a hyphen to specify the range of chapters to set as `chapFrom-chapTo:level`, so `1-3:5` means chapter 1 through 5 should be extracted with the depth level 5.
-
-Example:
-```
-  --depth 2          The default level 2, all the chapters and
-                     sections will be extracted.
-  --depth 3,1:2,8:5  The default level 3, level 2 for Chap 1,
-                     level 5 for Chap 8.
-  --depth 1,3-8:2    The default level 1, level 2 for Chap 3 to 8.
-  --depth 3-8:3      No default is set so default level is 1, and
-                     level 3 for chap3 to 8.`
-```
-
-## Custom CSS
-
-By default `asciidoctor-chunker.css` is included in the output directory.  It provides the non-opinionated page navigation at the bottom of every chunked page.  You can override this by giving a comma separated list of paths to your custom css files.  They are copied into the output directory so the paths must be accessible by `asciidoctor-chunker`.
-
-## About Strict Mode
-
-If you have any custom elements inserted under `<div id=#content></div>` in the source single html, `asciidoctor-chunker` ignores it by default.  If you want them to be included into the chunked html, set the option `--no-strictMode`.
-The element will be copied to every chunked page.
-
-## Customizing Titlepage
-
-The `index.html` created by `asciidoctor-chunker` is selected by clicking the word **Titlepage** in the table of contents. To change the default value, use the option `--titlePage [string]` where `[string]` is the desired text.
-
-## Example
-
-The project contains the `example` directory where you can generate the chunked html for the [Asciidoctor User Manual](https://asciidoctor.org/docs/user-manual/) by invoking `make`.  Simply go into the `example` directory and invoke `make`.  This will clone the asciidoctor project from the github for the first time, then the chunked html will be generated under `test/output-chunk/html_chunk/` directory.  The `index.html` is the first page.

You can override\n  it with the '-o' option.\n\n  The default splits are made by preamble, parts, and chapters.\n  You can specify the extraction level with the '--depth' option.\n\n  If you have any custom elements inserted under <div d=#content>\n  in the source single html, asciidoctor-chunker ignores it by\n  default. If you want them to be included into the chunked html,\n  set the option --no-strictMode. The element will be copied to\n  every chunked page.\n\n  By default asciidoctor-chunker.css is included in the\n  output directory. It provides the non-opinionated page\n  navigation at the bottom of every chunked page. You can\n  override this by giving a comma separated list of paths\n  to your custom css files. They are copied into the output\n  directory so the paths must be accessible by\n  asciidoctor-chunker.\n\nThe Depth Specifier:\n  You can list the multiple settings by connecting each\n  specifier with a comma. Each specifier is consisted of\n  either a single number or a collon separated with two\n  numbers.\n\n  The single number sets the default level of extraction.\n  Number 1 is the application's default and it extracts the\n  chapter level. Number 2 for section extraction, 3 for\n  subsection, and so on to 6 which is the maximum section\n  level of Asciidoctor.\n\n  The list of collon separated numbers, chap:level, can\n  change the extraction depth for specific chapters,\n  so 3:2 means chapter 3 is extracted down to 2 levels (i.e.\n  section level). You can use a hyphen to specify the range\n  of chapters to set as chapFrom-chapTo:level, so 1-3:5 means\n  chapter 1 through 5 should be extracted with the depth\n  level 5.\n\nExample:\n  --depth 2          The default level 2, all the chapters and\n                     sections will be extracted.\n  --depth 3,1:2,8:5  The default level 3, level 2 for Chap 1,\n                     level 5 for Chap 8.\n  --depth 1,3-8:2    The default level 1, level 2 for Chap 3 to 8.\n  --depth 3-8:3      No default is set so default level is 1, and\n                     level 3 for chap3 to 8.").parse(e),{args:n,depth:r,outdir:i,strictMode:s,titlePage:o,css:a=["asciidoctor-chunker.css"]}=t;1!==n.length&&t.help();const c=(e=>e.split(",").map((e=>{const[t,n]=e.split(":");return n?F(t,n):{default:+t}})).reduce(((e,t)=>({...e,...t})),{default:1}))(r);return{singleHTML:n[0],config:{depth:c,outdir:i,css:a,strictMode:s,titlePage:o}}})(process.argv);(async(r,i=U)=>{const{outdir:s}=i;await l(s)||await a(s);const o=(c=s,(e,n)=>{const r=t.format({dir:c,base:`${e}.html`});h.writeFile(r,n.html()).catch((e=>console.log("File write error:",r)))});var c;const u=(p=r,n.load(e.readFileSync(p)));var p;L(r,s)(u.root()),T(o,u,i),console.log(`Successfully chunked! => ${t.join(s,"index.html")}\n`)})(B,G)})()})();

-# usage: htmldiff [[-c] [-l] [-o] oldversion newversion [output]]
-#
-# -c - disable metahtml comment processing
-# -o - disable outputting of old text
-# -l - use navindex to create sequence of diffs
-# oldversion - the previous version of the document
-# newversion - the newer version of the document
-# output - a filename to place the output in. If omitted, the output goes to
-#          standard output.
-#
-# if invoked with no options or arguments, operates as a CGI script. It then
-# takes the following parameters:
-#
-# oldfile - the URL of the original file
-# newfile - the URL of the new file
-# mhtml - a flag to indicate whether it should be aware of MetaHTML comments.
-#
-# requires GNU diff utility
-# also requires the perl modules Getopt::Std
-#
-# NOTE: The markup created by htmldiff may not validate against the HTML 4.0
-# DTD. This is because the algorithm is realtively simple, and there are
-# places in the markup content model where the span element is not allowed.
-# Htmldiff is NOT aware of these places.

-"""Used for automatic reflow of spec sources to satisfy the agreed layout to
-minimize git churn. Most of the logic has to do with detecting asciidoc
-markup or block types that *shouldn't* be reflowed (tables, code) and
-ignoring them. It's very likely there are many asciidoc constructs not yet
-accounted for in the script, our usage of asciidoc markup is intentionally
-somewhat limited.
-
-Also used to insert identifying tags on explicit Valid Usage statements.
-
-Usage: `reflow.py [-noflow] [-tagvu] [-nextvu #] [-overwrite] [-out dir] [-suffix str] files`
-
-- `-noflow` acts as a passthrough, instead of reflowing text. Other
-  processing may occur.
-- `-tagvu` generates explicit VUID tag for Valid Usage statements which
-  don't already have them.
-- `-nextvu #` starts VUID tag generation at the specified # instead of
-  the value wired into the `reflow.py` script.
-- `-overwrite` updates in place (can be risky, make sure there are backups)
-- `-check FAIL|WARN` runs some simple sanity checks on markup. If the checks
-  fail and the WARN option is given, the script will simply print a warning
-  message. If the checks fail and the FAIL option is given, the script will
-  exit with an error code. FAIL is for use with continuous integration
-  scripts enforcing the checks.
-- `-out` specifies directory to create output file in, default 'out'
-- `-suffix` specifies suffix to add to output files, default ''
-- `files` are asciidoc source files from the spec to reflow.

-# What Happened To The Vulkan Extension Loader?
-
-If you're looking for the files vulkan_ext.[ch] in this directory, they have
-been removed. There were two significant problems with these simple
-wrappers.
-
-First, vulkan_ext exported all extension entrypoints. However, the Vulkan
-loader also exports entrypoints for the window system integration
-extensions. If someone tried to compile a project and link it to both the
-loader and vulkan_ext, they would get a bunch of redefined symbols. This
-linking error is difficult to work around, because vulkan_ext does not have
-an easy method of disabling the entrypoints at compile time. It is possible
-to remove these entrypoints when generating vulkan_ext, but even then you
-have to manually compile a list of every single extension to be disabled.
-
-Second, each entrypoint is only stored once, regardless of how many
-instances or devices are created. This means that attempting to use multiple
-instances or devices in parallel can result in one device calling function
-pointers that are only valid on the other device, which will crash. You may
-be able to work around this by never initializing the device dispatch
-(vkExtInitDevice), but we haven't tried this.
-
-It is still possible to retrieve the last versions of these files in the
-Github KhronosGroup/Vulkan-Docs repository from the 'v1.1.75' release tag.
-It is also possible to regenerate them from ../../xml/vk.xml, although we
-are no longer maintaining the generator code and it may eventually stop
-working correctly. See README.adoc and the `extloader` Makefile target in
-that directory.

-= Introduction
-
-This document contains required procedures and conventions when writing
-specifications for new Vulkan APIs, extensions and layers, or related
-Khronos^{reg}^ documentation such as white papers and tutorials; or
-contributing to existing Vulkan specifications.
-These are collectively referred to as _Vulkan Documentation_ or just
-_documentation_ below.
-The primary focus is the API Specification and API extensions, although all
-of the markup and most of the writing style is equally applicable to other
-documentation.
-
-The primary purpose is to achieve consistency across the API, as well as
-across all of our source and output documents.
-Consistency makes it easier for developers, editors, reviewers, and users of
-our documentation to understand and modify it.
-
-This document is now formally voted on and approved by the Vulkan Working
-Group.
-This means that unless explicitly stated otherwise, the procedures and
-conventions must be followed.
-If you have a strong desire to modify the procedures and conventions, such
-changes must be made through the normal Vulkan Working Group processes.
-
-
-[[introduction-terminology]]
-== Terminology
-
-The key words *must*, *required*, *should*, *recommend*, *may*, and
-*optional* in this document are to be interpreted as described in RFC 2119
-and by the Vulkan Specification in the "`Terminology`" section.
-
-
-[[introduction-structure]]
-== Document Structure
-
-The style guide is broken into four sections:
-
-  * <<naming,API Naming Conventions>> - the required rules for choosing
-    names of Vulkan identifiers of all types.
-  * <<extensions,Extensions and Layers>> - the required procedures for
-    creating formal Vulkan extensions and layers.
-  * <<markup,Markup Style>> - the required and recommended markup style for
-    writing asciidoctor and XML source that follows consistent formatting
-    and layout guidelines, tags special terms and phrases for proper
-    processing by the spec generation tools, etc.
-  * <<writing,Writing Style>> - the required and recommended writing style
-    for overall and fine-grained structure and conventions, normative
-    language use, API naming conventions, common words and phrases to use
-    and to avoid, linking and cross-referencing, etc.
-
-
-[[introduction-asciidoc]]
-== Asciidoctor Markup
-
-Vulkan Documentation is primarily written in Asciidoctor, a text markup
-language.
-We use the command-line asciidoctor client that is actively maintained by
-asciidoctor, which is documented on its website at https://asciidoctor.org.
-
-References to the Asciidoctor User Manual are to sections in the document at
-https://asciidoctor.org/docs/user-manual/.
-
-Asciidoctor is implemented in Ruby (https://www.ruby-lang.org/), which is
-available for Linux, MacOS, and Microsoft Windows.
-
-[NOTE]
-.Note
-====
-There are other implementations of asciidoctor, such as AsciidoctorJ
-(https://github.com/asciidoctor/asciidoctorj) and asciidoctor.js
-(https://github.com/asciidoctor/asciidoctor.js).
-In particular, GitHub and GitLab both have preview renderers for .adoc or
-.asciidoc files in repositories, and live preview extensions exist for
-Chrome and Firefox.
-
-However, because of the use of custom Ruby macros in the Vulkan
-Specification toolchain, and the high complexity of the documents and
-toolchain used to generate it, these web tools cannot currently render the
-Specification from source.
-Instead, we generate HTML and PDF versions of the Specification and publish
-them on the Khronos website.
-
-The Asciidoctor toolchain and build process are not addressed by this
-document, which concentrates solely on source documents.
-====
-
-
-[[introduction-normative]]
-== Normative References
-
-Normative references are references to external documents or resources to
-which documentation authors must comply.

-= Vulkan^(R)^ API Registry Build Instructions and Notes

-
-[[intro]]
-== Introduction
-
-This is the Vulkan XML API Registry. It is used to generate the canonical
-`vulkan_core.h`, the API Asciidoc include files used by the Vulkan
-Specification and Reference Pages, and many other types of generated files.
-
-When changes to generated files are needed, follow this workflow.
-Normally changes are needed only when defining a new extension or core
-version of the API.
-
-  * Clone the repository and create a branch to work in locally
-  * Edit `vk.xml`
-  * `make install test`
-  ** This generates headers in `../gen/include/vulkan` including
-     `vulkan_core.h` and a set of platform-dependent headers
-     `vulkan_<platform>.h`.
-  * `(cd .. && make generated)`
-  ** This uses `vk.xml` to generate asciidoc includes and other intermediate
-     files in `../gen` for the specification build.
-     There are many ways to invoke the Makefile in `..`.
-     This simple recipe only generates includes for the core Vulkan API
-     without any extensions.
-     See `../BUILD.adoc` for more.
-  * Repeat until the headers and/or includes are correct
-  * Commit your changes to your local git branch, push to your upstream git
-    server (your personal repository clone of KhronosGroup/Vulkan-Docs on
-    Github, for people outside Khronos; the Khronos member gitlab server,
-    otherwise), and create a pull or merge request against the default
-    branch (currently `main`) or other appropriate target.
-
-For a detailed description of the schema, go to `..` and `make registry`,
-which generates `gen/out/registry.html`.
-This document also includes some examples of how to make simple changes in
-the API via the XML.
-
-The generator scripts are written in Python 3, using the `etree` package for
-processing XML.
-See `../scripts/README.adoc` for script descriptions.
-
-
-[[build]]
-== Build Environment
-
-We strongly recommend using the Khronos-provided Docker image, which has all
-needed build tools pre-installed.
-See `../BUILD.adoc` for details.
-
-It is possible to construct your own build environment on Linux, Windows, or
-MacOS by following the recipe in the Dockerfile for the Khronos-provided
-Docker image.
-
-
-[[files]]
-== Files
-
-  * `vk.xml` - XML API description.
-  * `registry.rnc` - RelaxNG compact schema for validating XML against the
-    schema.
-  * `Makefile` - generates headers from `vk.xml` (see <<targets,Makefile
-    Targets>> below).
-  * `../gen/include/vulkan/vulkan_core.h` - Generated Vulkan non-platform
-    API header.
-  * `../gen/include/vulkan/vulkan_<platform>.h` - Generated Vulkan platform
-    API headers.
-
-
-[[targets]]
-== Makefile Targets
-
-  * `install` (default target) - regenerate header files in
-    `../include/vulkan`.
-  * `test` - make sure `../include/vulkan/vulkan_core.h` compiles.
-    *Important!* Can also be used to test if platform headers compile by
-    specifying `make TESTDEFS=-DVK_USE_PLATFORM_<PLATFORM>_<AUTHORID> test`.
-  * `validate` - validate `vk.xml` against the schema. Requires installing
-    `jing` (see <<linux,Software Dependencies>> below). Also important!
-  * `clean_dirt` - remove intermediate files.
-  * `clean` - remove generated files.
-
-Generated files can be created in a directory other than the default
-`../gen/` by setting the Makefile variable `GENERATED` to that directory
-path.
-
-If you have trouble running the Makefile on your platform, the following
-steps will build `vulkan_core.h` and test that it compiles:
-
-[source,sh]
-----
-# Regenerate header from XML
-python3 ../scripts/genvk.py -o ../include/vulkan vulkan_core.h
-# Verify that the resulting header compiles
-gcc -Wall -c -I../include testcore.c
-g++ -Wall -c -std=c++98 -I../include testcore.c
-g++ -Wall -c -std=c++11 -I../include testcore.c
-----
-
-
-[[history]]
-== Revision History
-
-  * 2020-08-25 -
-    Update for new default branch (`main`).
-  * 2019/05/12 -
-    Bring up to date with changes in file paths and build tools.
-  * 2019/03/10 -
-    Update for script reorganization.
-  * 2018/05/21 -
-    Don't generate vulkan_ext.[ch] from the `install` target. Add a new
-    shortcut `extloader` target for people still using this code and needing
-    to regenerate it.
-  * 2018/03/13 -
-    Update for new directory structure.
-  * 2018/03/06 -
-    Update for Vulkan 1.1 release and `master` branch.
-  * 2015/09/18 -
-    Split platform-specific headers into their own vulkan_<platform>.h
-    files, move vulkan.h to vulkan_core.h, and add a new (static) vulkan.h
-    which includes appropriate combinations of the other headers.
-  * 2015/06/01 -
-    The header that is generated has been improved relative to the first
-    version. Function arguments are indented like the hand-generated header,
-    enumerant BEGIN/END_RANGE enums are named the same, etc. The ordering of
-    declarations is unlike the hand-generated header, and probably always
-    will because it results from a type/enum/function dependency analysis.
-    Some of this can be forced by being more explicit about it, if that is a
-    big deal.
-  * 2015/06/02 -
-    Per WG signoff, converted hex constant values to decimal (for
-    non-bitmasks) and VK_BIT macros to 'bitpos' attributes in the XML and
-    hex constants in the header. Updated schema to match. Changed <ptype>
-    tag to <type>.
-  * 2015/06/03 -
-    Moved into new 'vulkan' tree (did not bother preserving history in
-    previous repo). Added semantic knowledge about structs and unions to
-    <type> tags instead of just imbedding C struct definitions. Improved
-    registry.rnc schema a bit.
-  * 2015/06/07 -
-    Incorporate feedback from F2F including Python 3 and Windows fixes to
-    the scripts. Add documentation to readme.pdf. Fold in multiple merge
-    requests resulting from action items agreed at the F2F, to prepare
-    for everyone moving to XML instead of directly editing the header.
-  * 2015/06/20 -
-    Add vulkan-docs target and instructions for installing python3 and
-    python-lxml for Windows.
-  * 2015/08/13 -
-    Bring documentation up to date with Makefile targets (default is now
-    ../include/vulkan.h).
-  * 2015/09/02 -
-    Update README with required (or known working) versions of toolchain
-    components.
-  * 2015/09/02 -
-    Move include/vulkan.h to vulkan/vulkan.h so #include "vulkan/vulkan.h"
-    is the normal usage (Bug 14576).
-  * 2016/02/12 -
-    Update README and remove old files to stage for public release.
-  * 2016/05/31 -
-    Remove dependency on lxml.
-  * 2016/07/27 -
-    Update documentation for changes to schema and generator scripts.
-  * 2016/08/26 -
-    Move README to an asciidoc file and update for the single-branch model.
-    Use 'clean' target to remove generated files in both spec source and
-    registry Makefiles.
-  * 2017/02/20 -
-    Move registry.txt (schema documentation) to the Vulkan spec source
-    directory and update the README here.

-#   requires - name of another type definition required by this one
-#   bitvalues - for a *Flags type, name of an enum definition that

-#   name - name of the type being defined
-#   category - if present, 'enum' indicates a matching <enums>
-#       block to generate an enumerated type for, and 'struct'
-#       causes special interpretation of the contents of the type
-#       tag including ... TBD ...
-#       Other allowed values are 'include', 'define', 'handle' and 'bitmask',
-#       which don't change syntactic interpretation but allow organization in
-#       the generated header.
-#   parent - only applicable if category is 'handle'. Notes another type with
-#       the 'handle' category that acts as a parent object for this type.
-#   returnedonly - only applicable if category is 'struct'. Notes that this
-#       struct is going to be filled in by the API, rather than an application
-#       filling it out and passing it to the API.
-#   structextends - only applicable if category is 'struct'. Lists parent
-#       structures which this structure may extend via the pNext chain
-#       of the parent.
-#       When present it suppresses generation of automatic validity for the
-#       pNext member of that structure, and instead the structure is added
-#       to pNext chain validity for the parent structures it extends.
-#   allowduplicate - only applicable if category is 'struct'. pNext can include
-#       multiple structures of this type.
-#   objtypeenum - name of VK_OBJECT_TYPE_* API enumerant which corresponds
-#       to this type. Currently only specified for category="handle" types.
-#   comment - descriptive text with no semantic meaning
-# For types without a category, contents include
-#   <apientry /> - substitutes for an APIENTRY-style macro on output
-#   <name> - contains name of the type being defined
-#   <type> - contains name of types used to define this type. There
-#       may be multiple imbedded <type> tags
-# For types with category 'enum', contents should be empty
-# For types with category 'struct', contents should be one or more
-#   <member> - like <param> for a struct or union member
-#       len - if the member is an array, len may be one or more of the following
-#           things, separated by commas (one for each array indirection): another
-#           member of that struct, 'null-terminated' for a string, '1' to indicate it's
-#           just a pointer (used for nested pointers), or a latex equation (prefixed with
-#           'latexmath:')
-#       altlen - if len has latexmath equations, this contains equivalent C99
-#                expressions separated by commas.
-#       externsync - denotes that the member should be externally synchronized
-#           when accessed by Vulkan
-#       optional - whether this value can be omitted by providing NULL (for
-#           pointers), VK_NULL_HANDLE (for handles) or 0 (for bitmasks/values)
-#       selector - for a union member, identifies a separate enum member that
-#           selects which of the union's members are valid
-#       selection - for a member of a union, identifies an enum value indicating the member is valid
-#       noautovalidity - tag stating that no automatic validity language should be generated
-#       values - comma-separated list of legal values, usually used only for sType enums
-#       limittype - only applicable for members of VkPhysicalDeviceProperties and
-#           VkPhysicalDeviceProperties2, their substrucutres, and extensions.
-#           Specifies the type of a device limit.
-#           Valid values: 'min', 'max', 'bitmask', 'range', 'struct', 'noauto'
-#       objecttype - only applicable for members representing a handle as
-#           a uint64_t value. Specifies the name of another member which is
-#           a VkObjectType or VkDebugReportObjectTypeEXT value specifying
-#           the type of object the handle references.
-#   <comment> - containing arbitrary text (unused)
-#
-# *** There's a problem here: I'm not sure how to represent the <type>
-# syntax where it may contain arbitrarily interleaved text, <type>, and
-# <enum> child tags. This allows only the syntax

-This file, vk.xml, is the Vulkan API Registry. It is a critically important
-and normative part of the Vulkan Specification, including a canonical
-machine-readable definition of the API, parameter and member validation
-language incorporated into the Specification and reference pages, and other
-material which is registered by Khronos, such as tags used by extension and
-layer authors. The authoritative public version of vk.xml is maintained in
-the default branch (currently named main) of the Khronos Vulkan GitHub
-project. The authoritative private version is maintained in the default
-branch of the member gitlab server.

-                In the current header structure, each platform's interfaces
-                are confined to a platform-specific header (vulkan_xlib.h,
-                vulkan_win32.h, etc.). These headers are not self-contained,
-                and should not include native headers (X11/Xlib.h,
-                windows.h, etc.). Code should either include vulkan.h after
-                defining the appropriate VK_USE_PLATFORM_platform
-                macros, or include the required native headers prior to
-                explicitly including the corresponding platform header.
-
-                To accomplish this, the dependencies of native types require
-                native headers, but the XML defines the content for those
-                native headers as empty. The actual native header includes
-                can be restored by modifying the native header tags above
-                to #include the header file in the 'name' attribute.

-        Unlike OpenGL, most tokens in Vulkan are actual typed enumerants in
-        their own numeric namespaces. The "name" attribute is the C enum
-        type name, and is pulled in from a type tag definition above
-        (slightly clunky, but retains the type / enum distinction). "type"
-        attributes of "enum" or "bitmask" indicate that these values should
-        be generated inside an appropriate definition.

-                    This extension requires buffer_device_address functionality.
-                    VK_EXT_buffer_device_address is also acceptable, but since it is deprecated the KHR version is preferred.

-                    These enums are present only to inform downstream
