No, SyncReply is NOT perMessage. I added a paragraph in 6.1 to cover this issue. My problem is that you never know if there is an intermediary so should you always include SyncReply if SyncReplyMode not equal *none*? If SyncReply is included, it will make it all the way to the end (one hop at a time), isn't there always a potential for mismatch? If it is always going to be pass all the way through, why put actor=next? If it is always included, then why bother with it in the CPA? What was the value of taking this out of QualityOfServiceInfo and making it an element? IMO, we just added 100+ bytes for nothing. Regards, David.
