Subject: NEW ISSUE: Is an implementation supporting a smaller max messagenumber valid? [Re: [ws-rx] NEW ISSUE: Max message number in policy]
*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] thanx, doug On 12/07/05 07:39, Doug Davis wrote: > > *Title*: Max message number in policy > *Description*: define a policy assertion that defines the highest > message number the RM destination will accept. > *Justification*: without knowing in advance what the highest message > number is the RM source may exceed it, causing the entire sequence to be > terminated - when it may have been able to start a 2nd sequence to > continue its work.
