class ProtocolRef (Reference):
	'''
	A URI reference to get a copy of a profile. This usually is a "ws://"
	(websocket) URI, allowing users (parties) to get notifications if the profile
	is changed.
	<p>
	In debugging scenarios, this is usually a "file://" URI, in which case the
	profile is assumed to be static during the run. Parties that support
	debugging eg with the simplerunner should support the file: protocol.
