Why not?

And if an extension is the right place to define scope syntax and 
semantics, then I would suggest to move the scope parameter(s) to that 
extension, too. A scope parameter without a clear definition in the core 
endangers interoperability.

Regarding relations between authz servers, resource server and clients, 
we have the following requirements:

We definitely need support for deployments w/ 1 authz server, n 
resources servers, and m clients. At least resource servers and clients 
must be identifiable at the protocol level. I don't prefer a certain way 
of resource server identification: dedicated server_ids, including the 
server id within scopes or any other solution is acceptable.

We would like to see support for specifying permissions on resource 
servers. I think scope would be the natural way of specifying them.

What do others think?

regards,
Torsten.
