Ok.

So what is not generic OAuth 2.0 (+ OAuth introspection) is the following:

cnf
scope
profile
rs_cnf
req_aud
req_cnf
used_cnf


I am aware of your point-of-view on the 'profile' parameter and I 
disagree with it (I feel it is sufficient to make it OPTIONAL).

What are your thoughts about the other parameters (keeping in mind that 
'req_aud', 'req_cnf' and 'used_cnf' are going to replace the use of 
'aud' and 'cnf' in the ACE request/response interactions)?.

Ludwig
