	</brief_description>
	<description>
		[OpenXRAPIExtension] makes OpenXR available for GDExtension. It provides the OpenXR API to GDExtension through the [method get_instance_proc_addr] method, and the OpenXR instance through [method get_instance].
		It also provides methods for querying the status of OpenXR initialization, and helper methods for ease of use of the API with GDExtension.
