I brought the issue up to Dale Moberg for a separate document describing the oasis:names:tc:ebxml-cppa:partyid-type URN. It can be maintained independently of the CPP/A specification, and referred to from any of the CPP/A, Registry and Messaging Services specs. If someone would ask me nicely to devise the document, I might consider volunteering! William J. Kammerer Novannet, LLC. +1 (614) 487-0320 +1 (614) 638-4384 (c) +1 (928) 396-6310 (FAX)
