David: You asked me to check the contents of the Via element to see if the Via element can be omitted when QOS is BestEffort for the single-hop case: ><db>Not sure this works. There are additional attributes in the NAD (Via) >element that are currently required such as syncReply. Arvola. Can you ckeck >the spec and determine which is optional which is required and specify what >the default semantic should be for each of these elements/attributes if the >NAD/Via is not present.</db> Your proposed change #11 calls for having syncReply both under MessageHeader and Via, so for the single-hop BestEffort case, the information can be obtained from the MessageHeader. The elements and attributes under Via are: - CPAId -- not needed for single-hop - Service -- not needed for single-hop - Action -- not needed for single-hop - id -- not needed when Via is not present - version -- not needed when Via is not present - actor -- not needed when Via is not present - syncReply -- can be obtained from MessageHeader - reliableMessagingMethod - not needed when QOS is BestEffort - ackRequested -- not needed when QOS is BestEffort Therefore, my conclusion remains that the Via element is not needed when QOS is BestEffort and no intermediary is involved.
