Hi Sunil,
I see a few potential issues with the proposed opton:
 i) Get rid of MId and have GId/Sid set. Gid could be optional & SId
    is mandatory. If Gid is present, SId is the unique in that GId. If not,
    SId should be globally unique.

(1) RM would use a GId/SId set to uniquely identify messages, while other features /
extensions in the same SOAP message may use a different mechanism(s).  Could get
pretty messy and difficult to manage and synchronize.

(2) Even where sequencing is not required, a GId/SId set would be required to uniquely
identify messages for other RM features.

It seems preferable to provide a message identification mechanism that isn't coupled
with sequencing or any particular feature.  That was the intent in the current
WS-Reliability spec where MessageID is in the MessageHeader with other 'generic'
information such as From, To, etc., and GroupID and SequenceNumber are in the
MessageOrder header and only used for ordering.
