		Delegation info PIP
		No delegation	Service Provider	Entitled Party	Authorization Reg
Auth info PIP	Service Provider	3.	3a	3b	3c

*The Identity Provider cannot hold explicit authorization info, but it can hold info about a Human Service Consumer's identity that implies authorization - i.e. 'working for truck company X'

As no delegation takes place, the legal entity fulfilling the Entitled Party-role also fulfils the Service Consumer-role.

Note that an Identity Broker is can be introduced to broker the relation between the Service Provider and the Identity Provider(s) and/or the Service Provider and the Authorization Registry(s). This is optional and useful in situations with several Identity Providers and/or Authorization Registries.
