That XPath cannot (in XPath 1.0 context, anyway) identify anything in
your documents (either version).  XPath 1.0 specifically states that
the default namespace declaration has _no effect_ on the
interpretation of XPaths, so the occurrences of 'Payload' and 'MsgID'
in the above path should never match any ns-qualifed elements, an in
particular should fail to match anything in _either_ version of your
documents, since all the elements therein are ns-qualified.

So either you're not reporting the situation accurately, or _both_
processors are broken.
