My use case is indeed similar to  assertion flow "section 6.3.  Client 
Acting on Behalf of a User".
Differences are:
1.  if my use case is carried out in assertion framework, "pricipal" 
should be client, while assertion document does not 
include client as an option when client is acting on behalf of a 
user(resource owner), it says  " an authorized accessor for which the 
access token is being requested (typically the resource owner, or  an 
authorized delegate)."
2.  if my use case is carried out in assertion framework, "issuer" should 
be resource owner, while assertion document only includes 
client and token service 

In my use case the "assertion" is more like a private output, while in 
assertion flow "assertion " is generated by a thrid party token service or 
by client itself.

Re: Re: [OAUTH-WG] Hi,any comment on draft-zhou-oauth-owner-auth?






Your usecase sounds a little bit like the assertion flow. 
The RO issues an assertion and the rest goes. 
Is there reasons that an assertion flow cannot do?
