Re: [OAUTH-WG] I-D Action: draft-ietf-oauth-jwsreq-22.txt

I just read over the diff between -21 and -22 and realised the example in Section 5.2.2.

https://server.example.com/authorize?
       response_type=code%20id_token
       &client_id=s6BhdRkqt3
       &request_uri=https%3A%2F%2Ftfp.example.org%2Frequest.jwt
       %2FGkurKxf5T0Y-mnPFCHqWOMiZi4VS138cQO_V7PZHAdM

 still has the “response_type" parameter. I think this parameter should be removed.
