This file, xr.xml, is the OpenXR API Registry. It is a critically important
and normative part of the OpenXR 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 xr.xml is the one
maintained in the default branch of the Khronos OpenXR GitHub project.

because they are recursive structures and this is easier than modifying the tooling
