RE: Issue: How CPA is used in the spec

[David Fischer <david@drummondgroup.com>]

Correct,  CPAId is not optional, but it does not necessarily point to a CPA.
It's the CPA that's optional.  CPAId might point to my own personal TP
database entry or it might just be something I make up for purposes of this
particular message (bootstrap situation).

David Fischer

I'm sorry, when did the CPAId element become optional? It certainly
isn't "optional" in the XSD and to my knowledge has never been. I honestly
don't
know where this is coming from.

What is OPTIONAL is that you have an actual CPA Instance document
that the MSH, or the software which uses the MSH, references directly
during runtime.

The "virtual" CPA is not optional, it is an integral part
of the MSH and has been, as John Ibbotson rightly pointed out in
yesterday's call, since the very earliest days of our effort.

I prefer the previous wording (below).

Cheers,

Chris
