This mail is my contribution for fixing the definition for ReplyToShall we call it 'Response' since we decided to call the first pattern
element. I also made necessary
changes to the ackRequested element to get rid of the words
"asynchronous" and "synchronous".--------------------
The current text states:
“
*3.2.2. ReplyTo Element*
This is a REQUIRED element, used to specify the initial sender’s
endpoint to receive anasynchronous Acknowledgment message or Fault Message. The value of this
element isREQUIRED to be URL as defined in [RFC 1738].
“
However this does not properly reflect the differences between use of
the replyacknowledgment binding pattern and the callback acknowledgement pattern.
Lets first modify the definition for the AckRequested element to change
the use of theterms synchronous and asynchronous to the new terms “reply
acknowledgment pattern”and “callback acknowledgement pattern”.
“*3.2.4. AckRequested Element*
The AckRequested element is an OPTIONAL element. It is REQUIRED for
guaranteeing message delivery and message order. However this element
MUST NOTappear in a non-Reliable Message. This element is to be used for a
sender to request thereceiver to send back an Acknowledgment message for the message sent. The
AckRequested element contains the following attribute:
- an *ackPattern *attribute
*(1) ackPattern attribute*
The ackPattern attribute is an OPTIONAL attribute. This attribute is
used to specifywhether the Acknowledgment Message should be sent back directly in the
reply to the reliable message orin a separate callback request. This attribute, when used, MUST have one
of the following two values.The default value of this attribute is “Reply”, when omitted.
It may also be useful to add a third value call 'Poll', to indicate client's
- *Reply *: An Acknowledgment Message MUST be sent back directly in the
Reply to the Reliable Message.- *Callback*: An Acknowledgment Message MUST be sent as a callback
request, using the address in the ReplyTo element“
I'd also suggest to remove 'ReplyTo' as a sub-element of
With this modification the ReplyTo definition can be modified as follows:“
*3.2.2. ReplyTo Element*
This is an OPTIONAL element, used to specify the initial sender’s
endpoint to receive a callbackAcknowledgment message or Fault Message. A value of this element MUST be
present in the requestmessage if the AckRequested element indicates that the Callback
Acknowledgement pattern is requested.If present, the ReplyTo element is required to be URL as defined in [RFC
1738].“
