Re: Re: [OAUTH-WG] Last Call: <draft-ietf-oauth-assertions-08.txt> (Assertion Framework for OAuth 2.0) to Proposed Standard

[zhou.sujing@xxxxxxxxxx]

From the language, I got an impression that assertion
is only generated by token service after clients presenting some credentials,
there are may be some cases that "assertion"
don't need client's credential.
e.g., Resource owner as a token service  could
generate "assertion" to a client he trusts, bu signing a statement
that "This delegation is given to a client called clinet-id 
for doing something for me".
