No problem.

I'd imagine that one of the main modes-of-operation for xkms would
be where a client has a configured responder that it trusts for
pretty much everything. In that case, if the client receives a
ds:Signature just containing a ds:KeyValue, then it can do a
validate on the ds:KeyInfo and request the responder to return
a binding. Its only when the binding comes back that the client
gets to see what it can treat as an authenticated identity for
the signer.

Nice side effect: if the xkms responder is not just a dumb x.509
front-end, then the signer and verifier don't have to use the
same name for the signer! One less thing to break interop.

Stephen.
