How about Internet Explorer? XHTML 1.1 *should not* be sent
with a text/html mime type.
http://www.w3.org/TR/xhtml-media-types/#summary
If you send it as application/xhtml+xml IE prompts you to
download the page or open it in another program.

If you send XHTML 1.1 as text/html nonetheless (via content
negotiation on the server, sending text/html when browsers don't
support application/xhtmlxml), you're effectively
going against the spec, and should really be sending compatible
XHTML 1.0 or even HTML 4.01.

Also...the strength of XHTML lies in the ability it gives
developer to mix other technologies (such as MathML) into the
same document and to do things like extending the spec with your
own DTDs. This type of support is, from what I remember, still
quite flaky even in other browsers, not just IE.
