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”.

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

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).

AckRequested element to the response message, the use RM-Reply Pattern
