RE: Mysterious appearance of xmlns="" in output

The head element in your Header template in in no namespace. Since there's
no prefix on it, it has to be in no namespace or the default namespace. And
since there's no default namespace in scope (in your stylesheet) for that
element, MSXML has to turn off the default namespace when serializing the
head element that it turned on with the html element. You have to think of
the elements in your stylesheet as being a completely independant XML
document form the result document.

Just move your default namespace declaration in your stylesheet up to the
xsl:stylesheet element and that will make all of the unprefixed elements in
your stylesheet be in the same namespace which is probably what you want. Or
you could but another default namespace declaration on your head element but
that could start to get cumbersome and error prone depending on the size of
your transform.

Hope this helps,
Jason
