+It is arguable that <a>verifiable credentials</a> or
+<a>verifiable presentations</a> should be used as authorization mechanisms
+that a <a>holder</a> could use to access various
+systems. This specification does not contemplate such a usage of verifiable
+credentials and MUST NOT be considered an authorization framework on its own.
+The Working Group did consider authorization use cases
+during the creation of this specification and is pursuing that work as an
+architectural layer that is built on top of this specification.
