[Openid-specs-ab] scopes

So that would be the same as the RP asking for all of the default user info parameters as optional. 

It would be up to the IdP and or user to determine what a RP gets, by default.

If the RP docent get a claim it needs then it would need to use the claims mechanism to request it specifically, by making a second request.

That could work. 

If the request object turns off the default claims then a RP only wanting a single claim like email could use the full profile.

Facebook and others currently use multiple scopes to control access to their user info like endpoints.
We need to see how they feel about this.

If all the IdP start making up there own scopes because they don't want to support claims then we have a interoperability issue.

Looking for feedback from Google and others.
