Defines a binding between an [OpenXRAction] and an XR input or output. This binding resource binds an [OpenXRAction] to inputs or outputs. As most controllers have left hand and right versions that are handled by the same interaction profile we can specify multiple bindings. For instance an action "Fire" could be bound to both "/user/hand/left/input/trigger" and "/user/hand/right/input/trigger". Add an input/output path to this binding. Get the number of input/output paths in this binding. Returns [code]true[/code] if this input/output path is part of this binding. Removes this input/output path from this binding. [OpenXRAction] that is bound to these paths. Paths that define the inputs or outputs bound on the device.
