No way, no how, does that pass validation in check 1.63!

The problem is that MSIE is uploading the file as application/xml
instead of text/html whenever you insert an XML PI at the beginning of
the file. The validator accepts this at face value and treats the file
as XML and never even tries to sniff out DOCTYPEs and similar.
Unfortunately there is a bug in the Validator that makes it treat
explicitly labelled XML (as opposed to "sneak XML" like XHTML) as pure
SGML (i.e. HTML). When SP in SGML mode is fed the XHTML DTD it chokes
producing the error message above.

The attached patch to "check" should take care of it[0].

HTH, -link


[0] - But note that I haven't done extensive testing so it may have odd
side-effects.
      I don't think so though...
