If OpenID Discovery is a single, separate, referencable spec, then it
doesn't even have to do that. OpenID Authentication 2.0 can just say
something like:

"OpenID is an open, extensible framework for associated identity services
with an identifier. Discovery of the metadata necessary for an OpenID
consuming application to access those services is specified by the OpenID
Discovery specification [reference here]."

Under this approach, discovery all identifiers (URLs, XRI i-names/i-numbers,
email addresses, phone numbers, etc.) would be handled by OpenID Discovery.
