Hi, >>>> Also to address Pauls comment complete.

I presume it is to be an identifier of something, and presumably there then need to be rules for > resolution/comparison/etc. Based on my understanding of the draft (please correct me if I'm wrong), it's only an identifier within a trust domain. What matters is that entities within that trust domain understand the semantics. But, assuming we want something "real", why is an IP address not allowed?
