And this even applies to XML documents with the encoding set in
the XML declaration. For example, if you this XHTML document
sent as 'text/xml' over HTTP:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html
  PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html>
  <head>
      <meta http-equiv="Content-Type" content="text/html;
charset=utf-16" />
...
</html>

The character encoding is *neither* 'iso-8859-1' nor 'utf-16',
but 'us-ascii'. (This will no doubt lead to many
interoperability problems.)
