RE: using Javascript in XSL-XML

I'd second everything that Michael has said, except to amend slightly the recommendation for using XML/HTML comment tags around script tag contents in XHTML docs.

The javascript programming language is not necessarily XML-well-formed and it has constructs that can break XHTML validation.  Ampersands, gt and lt used in conditionals cannot be escaped, document.write("some messy partial html fragment"); are not that uncommon, etc.

If you do need/want your page to validate, you can wrap script tag contents in XHTML comment tags on an as-needed basis, though it's maybe easier just to make it a general practice.
