IIRC correctly this should be an error, not a warning, and clients are
supposed to fall over on it.

Those contexts are specific to HTML and don't apply in XHTML.

Yes, it is an error, not a warning. The CSS validator couldn't parse
the XML because it had such an error in it.

As it said - 'it is recommended to use "&amp;"'

... except you are serving XHTML as text/html and have to contend with
the joys of having to make the XHTML as much like HTML as possible.

Since text/html XHTML can't gain any of the client side benefits of
XHTML I suggest you switch to HTML 4.01 (either in your source
document, or in a transformation during the publishing or serving

If you want to stick with XHTML, then I suggest you reread the
sections on script and style elements in the spec (in the changes from
HTML 4.01 section and in Appendix C).

(on the subject of Appendix C, you should also check out C2 as you are
missing some trailing spaces)
