RE: Questions prompted by the publication of WS-ReliableMessaging

Speaking from a technology consumer perspective, I completely agree with Assaf.

I'm quite comfortable with WS-Reliability (in solving my existing problem 
in this aspect) and have not much incentive to look at the another spec 
covering the same area.  I'm interested to see a condensed comparison 
summary with WS-Reliability because I'm not given time to *slowly* read 
every spec.  And I doubt other technology consuming companies will do that 

I've found it is usually one of the following reasons why I start carefully 
read a spec.
1) It is the FIRST proposed standard solution to solve my existing problem 
(e.g. I read WS-Reliability immediately after it is announced)
2) SOMEONE TOLD ME that this new spec address a better scope than the old 
spec, or have a better architectural approach to the existing problem (e.g. 
same reason I look at XML-Schema when we are using DTD).
3) Some SIGNIFICANT INDUSTRY MOMENTUM and vendors backing up the new spec 
(this is a political reason.  BPEL is a good example)

Best regards,
