We use XHTML because the wicket web framework recommends XHTML, and it's more strict than HTML4. Wicket does some limited validation of our XHTML syntax; but, it isn't comprehensive, and doesn't flag this case. I was running a snippet of the generated code through the W3C validator to troubleshoot a browser-specific rendering issue when I ran across this error.

I didn't know that script and style require CDATA in XHTML; it makes sense, but, it didn't occur to me. Maybe the W3C validator could detect this condition and provide a warning, before trying to parse the contained data? We'll correct our markup accordingly.

Thanks for your reply,

You don't use HTML, you use XHTML.
But you do not understand the difference.

Stick to HTML 4 as long as you don't understand XHTML.
