Based on feedback from a co-worker (see below), I have added a proposed
new XHTML test:

Subject: Testing for XHTML support

The current test for XHTML support simply checks if the browser does not
die when faced with the XHTML mime type. Browsers that treat it as HTML
will appear to pass even though they do not actually support XHTML. While
it is very hard to check if they produce an XML error if parsing fails
(which is what they should do if they support X[HT]ML), it is easy enough
to test for the other parts of XHTML, such as case sensitivity and

Case sensitivity:
html, body { background-color: green; }
HTML, BODY { background-color: red; }

Simple namespace support (without needing namespaced selectors in CSS):
attached namespace.xhtml (also tests case sensitivity)

Complex namespace support (needing namespaced selectors in CSS):
attached complexnamespace.xhtml (also tests case sensitivity and several
other possible hacks instead of real support)
