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 only authoritative version of vk.xml is the one
maintained in the master branch of the Khronos Vulkan Github project.
