How about following definition for Once-and-Only-Once?

  P. 49, Line 2009.
    The MessageOrder element MUST be used with the duplicateElimination
    attribute set to true.


    The MessageOrder element MUST be used with delivery behavior of
    Once-and-Only-Once. In the specification, the Once-and-Only-Once
    delivery behavior means that two conditions below are satisfied at
    same time:

    1) No lost message by one of following two mechanisms
        - Reliable messaging described in "7.5 ebXML Reliable Messaging
          Protocol". It means that the messages includes AckRequested
          element or Acknowledgment element.
        - Reliable communication protocol
    2) No duplicate message by the mechanism described in "7.5.6
       Duplicate Message Handling". It means that duplicateElimination
       attribute is set to true.
