Regarding this statement, MQSeries provides an application-level api that can be used to send a DR, but it is optional. That doesn't make MQSeries any less reliable. MQSeries nodes only concern themselves with ensuring that the message is safely persisted in the adjacent node/queue. Let's be careful. IBM MQSeries is a proprietary protocol and implementation that assumes, at least for the purposes of reliable messaging, that all nodes on the path have it. That enables it to guarantee exactlyOnce delivery with a minumum of fuss. ebXML does not have the luxury of that assumption. We can't make any assumptions on the implementations of any of the nodes. We have to make crystal clear what are the responsibilities of intermediate nodes to assure that reliable delivery goes all the way down the path. Some assurance that the message got there helps considerably for this open system. Regards, Marty ************************************************************************************* Martin W.

Someone please check for pods in David's office!!! More comments below. I won't <snip/> as this is a valuable artifact for the resolution of these issues. My comments with <cf1/> this go. Cheers, Chris ----------------------------------------------------- Chris Changea 4 & 5 suggest "Make the return of a Delivery Receipt required if deliverySemantics=OnceAndOnlyOnce" Arvola and David F agree with this whereas Chris Ferris disagrees. I can see benefits in both approaches. So I think we should talk about this on next Monday's conference call. See other comments below marked with <db1></db1> to distinguish from earlier comments.
