| The `VK_KHR_16bit_storage` extension allows use of 16-bit types in shader |
| input and output interfaces, and push constant blocks. |
| This extension introduces several new optional features which map to SPIR-V |
| capabilities and allow access to 16-bit data in code:Block-decorated objects |
| in the code:Uniform and the code:StorageBuffer storage classes, and objects |
| in the code:PushConstant storage class. |
| This extension allows 16-bit variables to be declared and used as |
| user-defined shader inputs and outputs but does not change location |
| assignment and component assignment rules. |

| === Promotion to Vulkan 1.1 |
| |
| All functionality in this extension is included in core Vulkan 1.1, with the |
| KHR suffix omitted. |
| The original type, enum and command names are still available as aliases of |
| the core functionality. |
