Yeah, that is a serious limitation to JSON.

What do you mean with 'fully namespaces claims' ?

That would be important in the future.

OpenID Connect comes from OpenID which I have understood as being geared towards individuals maintaining their net identity.
I've been think about what it would take to make OpenID Connect usable in an organization context or for that matter in the context of federations of organizations. Something which I'd like to see as in scope.

And the first thing I stumble across is the lack of/limited extensibility of the schema.
This is a major limitation.
There is just a matter of course that there isn't an organization out there that doesn't have at least one attribute that is specific to them (at least they think it is) that they just have to have in an identity provider for it to be usable in their context.
So having an implied namespace for the OpenID Connect attributes could we allow for 'fully qualified' attributes from other namespaces ?

For instance:

 "name": "Jane Doe"
 "given_name": "Jane",
 "family_name": "Doe",
 "email": "janedoe at example.com",
 "picture": "http://example.com/janedoe/me.jpg",
 "http://xmlns.com/foaf/0.1/title": "Ms"
