This was a philosophical trick to figure out. While it still seems useful to summarize the value of UMA by talking about three phases (of which the latter two are similar to OAuth), phase 3 is rather unexciting -- it's just the successful conclusion of the whole sequence. So, really, section 2.1.5 (with all of its predecessor steps) is phase 3! Is it worth pointing specifically to this subsection when talking about phase 3?

Maciej has promised to supply example content. I think we kept all example content that was in the older drafts that was still accurate.

This is a good question. Thomas, I think you made this choice; were you following OAuth's lead? It's worth discussing whether we should make certain parts of the UMA flow "optional together". For example, what if the resource server is colocated with the authorization server and has a closer relationship with it that doesn't require an expensive interoperable messaging protocol? Is this a case where we should define "conformance profiles"?
