Which answers my question, thanks.
The rest of this message seems to be off-topic for the users list so
I'm open to suggestion where the discussion should take place.

I don't think that's been ruled out. In InCommon, at least, the
previously mentioned extension has not been deployed AFAIK so we're
free to solve the problem any way we like.

If we think that registrars will support multiple policies, then yes, I agree.

As you probably know, the MDRPI SAML metadata extension carries the
registrar's policy URL in addition to the registrar's identifier, but
if the policy changes, the URL MUST change (according to the spec) so
I'm not seeing much value in keying off the policy.

I'm not following you there but clearly there is much to talk about
(and my need is immediate). Where should this discussion take place?
