NXP/MSXML confusion

[Chris Lovett]

	The way I see it the <Y> element satisfies the choice (x|y)
allowing it to move on to the sequence (s,t) which appears in the XML
correctly.  So I think MSXML is correct in saying the document is valid,
don't you agree ?

	By the way you can run msxml without the -d argument "java msxml
te.xml" and if no errors are displayed then the XML is valid.
