This is an illusion, I'm afraid.  If it were true that an existing IdP
deployment could easily participate in this profile (without
significant modification), we probably wouldn't need this profile (as
Scott has repeatedly argued).  In fact, a year and a half of effort
trying to do so suggests otherwise.

That said, we agree it is probably unwise to define a new Format, so
we will drop the NameQualifier requirement and use straight

A new profile document is forthcoming.  Actually, I've taken the
liberty to decompose the profile into a related set of reusable
profiles.  I hope to upload these by the end of this week.
