NEW ISSUE: Is an implementation supporting a smaller max messagenumber valid? [Re: [ws-rx] NEW ISSUE: Max message number in policy]

[Doug Bunting <Doug.Bunting@Sun.COM>]

*Title*: Is an implementation supporting a smaller max message number valid?

*Description*: The existing specification includes the clause "If the 
message number exceeds the internal limitations of an RM Source or RM 
Destination ...".  This allows a source or destination to handle 
unexpected failures gracefully.  It does not clearly allow, require, or 
prevent the implementation to be designed or deployed with a message 
number limit.  Should we support such a limitation?

*Justification*: Issue below presupposes a "yes" answer to this 
question.  Should decide this larger question before deciding how to 
fill gap left if the answer is "yes".

*Target*: core (RM spec)

*Type*: design

*Proposal*: I lean toward "no" but could be convinced otherwise.  If 
"no" is the answer, the specification could change to make it clear a 
WS-RM compliant implementation _must_ support the full unsigned long 
range for the message number.  That likely requires conformance 
terminology not presently in the specification; this issue is not 
intended to broach the even-more-general subject of conformance clauses. 
  My proposal therefore comes down to "close, no action".

*Related issues*: Max message number in policy [no number yet]
