I don't think we need to specify this.  People on the teams need to
understand that a PartyId is not necessarily the same as a whole
enterprise. As to whether a partyId can be equated to multiple enterprises,
I have no idea.  One would have to check the specs of the well-known
identifiers, such as DUNS, to see what they say.  Somehow, I doubt it.

Marty

One (or more) PartyId(s) can be equated to an enterprise.  Can a PartyId
ever be
equated to multiple enterprises?  I'm not sure we need to specify this --
implementation detail.

Dan,

The CPA is defined as being between two Parties, each having a PartyId.  If
I remember correctly, the MS spec defines Parties as the sender and
receiver of a message. What has to be made clear is that a business
enterprise may consist of many Parties, so that PartyId cannot be equated
with an enterprise. To make this clear, one may have to define the term
"enterprise" or another term that works for both very large and very small
companies.

Regards,
Marty

   OK, that's fine with me, as long as we make it very clear to our
   readership that a PartyId, *despite its name*, does not uniquely
   identify a "party".  Is that right?

   MWS:  Let's try this:  An enterprise may own one or more PartyIds.  A
   given
   PartyId belongs to only one enterprise.  In that sense, it is unique.

That's fine, as far as the relationship between "enterprise" and
"PartyId" goes.  But I also think we have to state that the
relationship between "PartyId" and "party" is *not* that a PartyId
identifies a party, as one might otherwise presume from the name.
