xsl validation error

I have a query for the validation team
 
the html response page in question is valid apart from this error
there is no attribute "xmlns:fo" 
however this namesapce is part of the xsl document type declaration as
you can see below which is generated automatically when its created in
xml spy
the namespacedirecly after it
'xmlns:msxsl="urn:schemas-microsoft-com:xslt"
exclude-result-prefixes="msxsl" ' was added later to allow node set
processing and does not cause a validation error
 
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
exclude-result-prefixes="msxsl" >

why is this causing a validation error?
 
thanks in advance
Gavin Harrison
