I suspect that some parsers interpret the presence of a <DOCTYPE>
declaration as an instruction to perform DTD validation, and that most
of your problems here are that you don't actually want DTD validation
done. A lot of the confusion here seems to be that DTD validation and
XSD validation are happening at the same time and the messages from both
are getting mixed up.
