OpenXR SDK 1.1.47 (2025-04-08)

This release features several new vendor extensions, one of which required a
modification to the XML schema for extending interaction profiles to represent
accurate. It also contains substantial fixes to the core_validation layer to
make it more usable and fix common false-positive validation errors, among other
improvements.

• Registry
  • Addition to XML registry schema: Specify interaction profile additions by
    constructing a predicate, and allow adding new top level /user paths to
    existing profiles. See SDK changelog and style guide for details.
    (internal MR 2467)
  • Chore: Reserve extension numbers.
    (internal MR 3729,
    internal MR 3744,
    internal MR 3745)
  • Fix: Reflect requirement of XR_META_hand_tracking_microgestures for
    XR_EXT_hand_interaction in xr.xml.
    (internal MR 3741)
  • Fix: Added missing comment on XR_EYE_POSITION_COUNT_FB to remove warning
    during build.
    (internal MR 3748)
  • Fix: typo in the documentation of XR_ERROR_SPACE_GROUP_NOT_FOUND_META
    (internal MR 3749)
  • Improvement: Fix schematron runner on Mac.
    (internal MR 3759)
  • New vendor extension: XR_META_detached_controllers
    (internal MR 2467)
  • New vendor extension: XR_BD_spatial_sensing
    (internal MR 3429)
  • New vendor extension: XR_BD_spatial_anchor
    (internal MR 3435)
  • New vendor extension: XR_BD_spatial_anchor_sharing
    (internal MR 3436)
  • New vendor extension: XR_BD_spatial_scene
    (internal MR 3438)
  • New vendor extension: XR_BD_spatial_mesh
    (internal MR 3439)
  • schema: Allow aliases of function pointers, primarily for use in extension
    promotion.
    (internal MR 2989)
• SDK
  • Validation Layer: Fix: Fixes validation layer check for next chain validation
    by changing it from recursive to iterative. This allows for subsequent struct
    to validate off the initial set of valid chained structs.
    (internal MR 3684,
    internal issue 2434)
  • Validation Layer: Fix: Fixes validation layer check for structs that inherit
    off a base struct. Inherited structs also have the same list of valid chained
    structs as their parent.
    (internal MR 3684,
    internal issue 2434)
  • Validation Layer: Fix: Fixes null dereference bugs in generated code in layer.
    (internal MR 3684,
    internal issue 2434)
  • Validation Layer: Fix: Adds a validation layer exception to
    xrGetRecommendedLayerResolutionMETA which allows a XR_NULL_HANDLE to be
    valid when checking the XrSwapchainSubImage struct.
    (internal MR 3689,
    internal issue 2425)
  • Validation Layer: Improvement: Add time stamp to the log messages
    (internal MR 3723)
  • Validation Layer: Improvement: Generate debug messages when core_validation
    layer starts / exits
    (internal MR 3723)
  • hello_xr: Improvement: Update Android target SDK version to 34 to eliminate
    Play Protect warning on install. (Minimum SDK remains 24.)
    (internal MR 3719)
  • list_json: Improvement: Use XrInstanceCreateInfoAndroidKHR on Android for
    improved compatibility.
    (internal MR 3775)
