The XrBodyJointSetFB enum is extended with a new joint set XR_BODY_JOINT_SET_FULL_BODY_META, which can be set as the joint set in the XrBodyTrackerCreateInfoFB info parameter to xrCreateBodyTrackerFB.

Description

These joint enumeration values index into the array returned by body tracking when the joint set XR_BODY_JOINT_SET_FULL_BODY_META is used. There are a total of XR_FULL_BODY_JOINT_COUNT_META joints in this set.

The joint indices shared with XrBodyJointFB have the same semantic meaning. The meaning of joint index 0 through XR_BODY_JOINT_COUNT_FB - 1 (69) matches the corresponding index in XrBodyJointFB.
