That's what happens if you serve your document as application/xml or text/xml (and don't use a style sheet).

In that case, my guess is that you've added appliction/xhtml+xm as a recognised MIME type in your Windows registry.

Both work fine in IE Windows here.
They are indeed served as application/xhtml+xml (at least to Opera). I can't check in IE right now (I'm on Linux). You're not using content negotiation to serve it as text/html to non-XHTML browsers?
