It does work, but only if you deliver the content in XHTML mode, that is, using 
a Content-Type of "application/xhtml+xml" (because then the browsers use their 
strict XML parser). Otherwise, when it is delivered as "text/html", Browsers 
will always use their HTML parser, even if you use a Doctype that declares the 
document as XHTML.
On a local Windows and Linux filesystem, if you save the file as .html, it will 
be treated by browsers as HTML, whereas if you save it as .xhtml, it will be 
treated as XHTML.

For example, if you use the following XHTML document:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";><head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title>Testpage</title>
<style type="text/css">
p { background-color: #F66; height: 50px; }
</style>
</head><body>
Text <p/> Text2
</body></html>

If you save this file as .xhtml on your filesystem and open it, the Browser 
will render the page correctly (the red <p> is between Text1 and Text2). At 
least it works with IE 9 (IE <= IE8 don't support XHTML), Firefox, Chrome and 
Opera. ;-)
