Also, you'll want a DTD and you should use an iso charset to overcome that "won't validate" issue Paul pointed out. For example:
<meta http-equiv="content-type" content="application/xhtml+xml; charset=iso-8859-1" />
Also, on your Browser Updates section, you should add Firefox, Opera, Safari, etc. Also, it isn't called Netscape Navigator anymore, but just Netscape.
