Issue 030 - 2 proposed resolutions

[Ian Robinson <ian_robinson@uk.ibm.com>]

Max and I have been working on some options for resolving issue 030 [1].
There has been a lot of good discussion on this issue already; we have
suggested 2 (different) concrete resolutions that we can discuss on the
call.
Proposal 1 is closer to the status quo; it retains the use of the
wsa:ReplyTo MAP for non-terminal notifications but adds a requirement for
terminal notifications to set wsa:ReplyTo to 'None'.

Proposal 2 replaces wsa:ReplyTo with wsa:From to further emphasize that
protocol message are never replies. This proposal also classifies WS-TX
"faults" raised during the agreement protocols (e.g. 2PC) as terminal
notification messages.

Proposal 1 (Issue30_Propsal_1_WSAT.doc)   (See attached file:
Issue30_Proposal_1__WSAT.doc)


Proposal 2 (Issue30_Propsal_2_WSAT.doc)   (See attached file:
Issue30_Proposal_2__WSAT.doc)

For either of these proposals, we believe WS-Coordination simply needs to
remove text that is already stated in WS-Addressing:
