It is possible for the resource server to seed discoverability of the resource owner context by populating the uri property of the resource set description with a network location that includes, say, a query parameter identifying the resource owner in some fashion. Then the authorization server application would need to either transmit the parameter value to a discovery service, or function as a discovery service itself, or perform some other mapping. If the authorization server application is able to map the network location to a substitute value, such as a one-time code or equivalent, and then report that value back to the resource server application, then they each can provision the code to the requesting party (say, in an email message) or client (say, in an error message) for it to be returned somewhere in the initial access attempt.
