    Gathering info from here and The WHATWG Blog, the minimal XHTML 5 document.
(This is served with Content-Type: application/xhtml+xml.)
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <title></title>
  <meta charset="UTF-8" />
</head>
<body>
</body>
</html>


Warning
XHTML must be served as application/xhtml+xml at the HTTP layer.
However, Internet Explorer only supports this in IE 9 and later.
(caniuse.com) Prior to that, IE requires that XHTML be served using the
erroneous Content-Type of text/html.


Note
The <!DOCTYPE html> is optional, but prevents browser quirks mode.
(The WHATWG Blog)


Note
The <meta charset="UTF-8" /> isn't strictly required, but is strongly
recommended. (See the MDN documentation for <meta charset> for reasons.)


Note
The XML declaration, <?xml version="1.0" encoding="UTF-8"?>, is not
required as long as the document in is UTF-8 (an XML decoder will assume
UTF-8). (The WHATWG Blog)
