Subject: Editorial comment on Application Notes for Reliable Response.
I think the wording "ack response not as critical" and "less critcal to ack response" could be improved. Suggested change: change: " Given the above, acknowledging a response message is not as critical as acknowledging a request message. Request acknowledgement (or failure to get one) is sufficient to ensure the following: (1) resending of the response message as a consequence of resending the request message, (2) delivery failure notification for both request and response, to the request Producer party. Because of this, it is less critical to acknowledge a response message than a request message. This response acknowledgement may be considered as optional, and will serve the following objectives: (a) More efficient cache management. (b) Notify the request Consumer party of failure to deliver its response message (even though the request Producer was also notified). In case an implementation adds the wsrm:Request element with an AckRequested element to the response message, the use RM-Reply Pattern value must be “Callback”. " to the following: " Given the above, request acknowledgement (or failure to get one) is sufficient to ensure the following: (1) resending of the response message as a consequence of resending the request message, (2) delivery failure notification for both request and response, to the request Producer party. However, without acknowledgment of the response, the response producer must be willing to cache each response until its request message expires since it is would not received delivery failure notifications for its responses. In some cases, a producer may choose to request an acknowlegement of receipt of its response messages.. This response acknowledgment will serve the following objectives: (a) More efficient cache management, since the response may be removed from the cache when its acknowledgment is received. (b) Notification the request Consumer party of failure to deliver its response message (even though the request Producer was also notified). In case an implementation adds the wsrm:Request element with an AckRequested element to the response message, the use RM-Reply Pattern value must be “Callback”.
