<h2>Analysis</h2>
<p>This test currently passes the XSS aspect but fails the validation aspect
due to generalized encoding issues. An augmented UTF-8 smoketest is
pending, until then, consider this a pass.</p>
<p>By making sure that UTF-8 is well formed and non-SGML codepoints are
removed, as well as escaping quotes outside of tags, this is a non-threat.</p>
