Well "...ish".

You can't write HTML 4.01 that conforms to XML standards, but XHTML 1.0 is a language that reimplements HTML 4.01 in XML.

The obvious change to give as an example is that <br> in HTML is <br/> in XHTML - but if you tried to use <br/> in HTML then it would mean the same as <br/>> (or a line beak followed by a greater than symbol).

So you can't just output XHTML and then slap an HTML Doctype on it. (Heck, its not really safe to serve XHTML as text/html despite what it says in Appendix C of the XHTML 1.0 Spec.)
