I agree. So my proposal for the line, considering the Doug Bunting's
comments too, should be revised as following:

  - P. 49, Line 2009 should be deleted.
  - Insert following sentences after line 2016.

        When the value of the messageOrderSemantics attribute is set to
        "guaranteed", delivery behavior Once-and-Only-Once MUST be used.
        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.
