Arvola,


I think you've hit upon an important point we need to clarify in your comments
on (6) below.  SyncReply should be meaningful with intermediaries between
the From and To parties.  It doesn't sound as if the CPP/A specification
makes this allowance.  I didn't think the MSH specification described only
receiving synchronous responses from the To Party.


I'd recommend it be possible for the From Party to request the first set
of MSH signals (errors or acknowledgments) from the "expected" party.  That
would support getting the acknowledgment back from the next MSH in the case
you've described below.  I'm not sure any changes are necessary in the MSH
specification in support of this.


On point (12) below, don't forget the sender performing retries as another
aspect of reliable messaging :-)  Of course, "reliable messaging" is an overblown/generic
term we've been avoiding in favour of better defined phrases like "once and
only once" (meaning "once or get a good error to the sending application").


later,

    doug
