RE: [ebxml-cppa] delivery channel selection

[Dale Moberg <dmoberg@cyclonecommerce.com>]

Thanks, Marty.

Tony, can we add this one to the
issues list and give it 1.1 targeting?

There may be other touch-ups in this area
because of our goal
of explicitly identifying multiple return paths
from the RespondingBusinessActivity side of things.

Most crucially, there needs to now definitely be
an explicit way of marking Sync sending, because
we had just relied on the absence of an endpoint
for receiving to "know" we had an expectation
of Sync style transport. Now we will have both
an endpoint (for some stuff coming back asynch)
as well as the synch mode for other stuff (Acks
typically). This also must be solved in 1.1.
(This solution will also need to use PackagingId 
overrides to mark out the differences in what
contents are included in the different return
paths.) Hope we can assemble all these
changes into a unified set by mid-November,
so we all have time to carefully review it 
and make certain it covers all the supported
uses.

Dale

ESSENTIAL VERSION 1.1 FIX

I just realized that there is a serious omission in the descriptions of
the
ServiceBinding and Override elements. The specification discusses the
delivery channel IDs under these elements as related to received
traffic.
While that is true as far as it goes, it leaves out an essential
statement.
The delivery channels specified under ServiceBinding and Override
relate
to this party's receive properties.The delivery channel actually used by
this party to send a message MUST be one of those under the PartyInfo
element of the OTHER party. The correct way to state the solution is to
add
text stating the the runtime MUST pick the correct channel from the
OTHER
party's ServiceBinding and Override elements under the same
CollaborationRole element.

Regards,
Marty
