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.
