OpenXR Specification 1.0.25 (2022-09-02)
This release contains a few specification clarifications and consistency
improvements, as well as some new vendor extensions. The spec generation
toolchain scripts have been synchronized with Vulkan, which adds some
additional detail to the generated spec document. The loader design
document has also been updated to correct an error and document the
loader’s API layer functionality now available on Android.

structures are “returnedonly”, which removes some unneeded
