Re: thy tiers might cease...

I understand, and it is kinda neat (I assume that's a typo in your
example, and it should be <ds:Signature/>).  HOWEVER, in a conventional
PKI, Locate is usually served by a directory such as LDAP; LDAP
directories do not sign their response.  Validate, on the other hand, is
done by things like OCSP (which do) or the Identrus RM. :)

Locate doesn't need a signature, because you can ask for the cert which
is itself signed. Validation is making more abstract statements about
the cert/key, and a relying party will probably require the entity
responding to sign things.

Does that help?
