Re: [ws-tx] Issue 030 - 2 proposed resolutions

[Mark Little <mark.little@jboss.com>]

Is there a reason why we can't combine some aspects of 1 and 2? 
Specifically, the concept of faults as terminal messages from option 2 
into option 1? At this point I don't see why the use of wsa:ReplyTo or 
wsa:From has any impact on how we treat fault messages: I think we've 
already agreed that we mean Application Messages That Convey Application 
Error/Fault Conditions and not the usual SOAP faults, which is why 
wsa:FaultTo probably doesn't make sense. But it seems that with that in 
mind, the classification of faults as terminal application 
messages/notifications can be done irrespective of whether we 
subsequently use wsa:ReplyTo or wsa:From.

I had to drop off the end of the last call, so maybe I missed something 
relevant?

Mark.
