| # During the development of Python 2.5, an attempt to move the "xml" | |
| # package implementation to a new package ("xmlcore") proved painful. | |
| # The goal of this change was to allow applications to be able to | |
| # obtain and rely on behavior in the standard library implementation | |
| # of the XML support without needing to be concerned about the | |
| # availability of the PyXML implementation. | |
| # | |
| # While the existing import hackery in Lib/xml/__init__.py can cause | |
| # PyXML's _xmlpus package to supplant the "xml" package, that only | |
| # works because either implementation uses the "xml" package name for | |
| # imports. | |
| # | |
| # The move resulted in a number of problems related to the fact that | |
| # the import machinery's "package context" is based on the name that's | |
| # being imported rather than the __name__ of the actual package | |
| # containment; it wasn't possible for the "xml" package to be replaced | |
| # by a simple module that indirected imports to the "xmlcore" package. | |
| # | |
| # The following two tests exercised bugs that were introduced in that | |
| # attempt. Keeping these tests around will help detect problems with | |
| # other attempts to provide reliable access to the standard library's | |
| # implementation of the XML support. | |
