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.
