Possibly.  We shouldn't duplicate authoritative information that can be obtained by querying the oauth-authorization-server-uri, but when necessary we should report values that apply only to the Printer such as the oauth-authorization-scope attribute (since an AS can have many more scopes than are used for printing...)
