Re: [OAUTH-WG] Review of draft-ietf-oauth-jwt-bearer-09

While a JWT might generically have many different audiences like resource servers, this profile is about sending it to the token endpoint at an AS for authentication or authorization.

I think adding something about the RS will confuse people.   

I think Brian's text is fine.

In some cases the "sub" (subject) claim can be a value representing an anonymous or pseudonymous user as described in Section 6.3.1 of the Assertion Framework for OAuth 2.0 Client Authentication and Authorization Grants [http://tools.ietf.org/html/draft-ietf-oauth-assertions-16#section-6.3.1].

The only question/comment I have is that I don't see any mention of privacy considerations in the referenced security sections.  COuld you add something?  It is easily addressed by section 10.8 of RFC6749, but there is no mention of privacy considerations.  I'm sure folks could generate great stories about who accessing what causing privacy considerations to be important.
