Hi Vladimir,

I think there should be client_id in the request as well.

See http://www.ietf.org/mail-archive/web/oauth/current/msg10636.html on
what I think.

In fact, I like it to go even further, but that may be too big a departure.
The cleanest way is to do like
but to avoid the path pollution, we would have to introduce URI template
and that means the client always need to be able to parse URI template
and that is probably asking too much to the client.
