swa66: Sorry I don't mean to be aggressive, but I do think it's silly for folks to still be posting duff advice about XHTML and DTD's from over a decade ago. The W3C XHTML2 Working Group was disbanded 4 years ago. Tim Bray suggested XML should drop the doctype 8 years ago. "HTML5" will be ten years old next year. The XML and HTML worlds have long since moved on.
HTML is gradually cleaning up all this pointless legacy SGML/XHTML complexity, and authors can already avoid this legacy stuff altogether by just using <!doctype html> in their web pages. That's what I would heartily recommend to everyone :)
