Re: [DS5] Request with acknowledgement - revised

This scenario assumes data is to be delivered from the sender to the
receiver. Therefore there are two
possible outcomes. Either the data was delivered or there was some failure.
I think the scenario should
be more prescriptive than the suggested changes. How about :

DS5     A sender wishes to reliably exchange data with a receiver.
        It wishes to be notified of the status of the data delivery
        to the receiver. The status may take the form of:
        1) The data has been successfully delivered to the receiver,
        or
        2) Some failure has occurred which prevents the sucessful
           delivery to the receiver.

instead of:

DS5   A sender wishes to exchange data with a receiver. Data is sent
      from the sender to the receiver, and a positive acknowledgement
      is returned to the sender indicating a successful transfer.

Note: DS5 differentiates from DS3 and DS4 in that an acknowledgement is
      semantically different from any business-level response which
      the receiver might send.  The acknowledgement only indicates a
      successful transfer of the message from one node to another.
