-If the [=XRDepthInformation/sensor=] is aligned with the associated [=XRDepthInformation/view=], the {{XRViewGeometry/transform}} and {{XRViewGeometry/projectionMatrix}} MUST be equivalent to the identity transform. These attributes MAY otherwise be used by experiences to better align with the real world.
+If the [=XRDepthInformation/sensor=] is aligned with the associated [=XRDepthInformation/view=], then all values included from {{XRViewGeometry}} MUST return the same values as the associated [=XRDepthInformation/view=] does.
