It's not correct. Here's the exact same XHTML document (verify by
viewing the source), served with different mimetypes:
Notice that the version served as HTML does not render properly. This
is because the browser is treating it as HTML with an unknown doctype,
not as XHTML.
I'm not debating that it's *possible* to serve HTML with an XHTML
mimetype and still see something rendered to the screen. Hundreds of
thousands of sites do so every day. But to call this XHTML is absurd.
