+	<description>
+		The DPad binding modifier converts an axis input to a dpad output, emulating a DPad. New input paths for each dpad direction will be added to the interaction profile. When bound to actions the DPad emulation will be activated. You should [b]not[/b] combine dpad inputs with normal inputs in the same action set for the same control, this will result in an error being returned when suggested bindings are submitted to OpenXR.
