Tend to agree with Antoine here - understanding what a profile is is best
supported by understanding the practical value (functionality) - including
content negotiation, validation and things like form configuration, but
also discovery modes.

Negotiation is probably the simplest of these - it has only a few
significant aspects AFAICT:
1) identity of profiles
2) possibly dereferencing identifiers to get more information
3) substitutability of subprofiles

The other requirements for profiles need more description (and hence
guidance).

Splitting the discussion is only sensible if negotation is a non-negotiable
requirement :-) In that case delegating these aspects of defintion and
behaviour to the negotiation team to define is the appropriate response, we
cant afford the time to allow separate threads to reinvent different sized
wheels here.
