I think that the Doug's change proposal about MessageOrder means:
    - When MessageOrder element appears, message order is guaranteed. If
      it does not appears, message order is not guaranteed.
    - The MessageOrder element has always SequenceNumber element inside.
Is that correct, Doug?

In the current specification (v1.09), SequenceNumber may appear even if
MessageOrderSemantics is set to NotGuaranteed so that receiving
application can use the SequenceNumber to guarantee message order by
itself. I think it was Chris's idea. See:

Doug's change proposal removes the feature. Chris, what do you think?
