If there is an existing interface that may fit the bill I'm not sure what
we are asking WSRF TC to do with the requirement.

Not suggesting that it is necessarily a third party.  It could (in simple
cases)
be implemented (if the implementer so chose) on the same endpoint as the
management interfaces.  This would essentially provide a query and
retrieval
mechanism for "related" WS-Resource and their respective EPRs.
