* <li>opening tag without its closing tag</li>
|

* <li>closing tag without its opening tag</li>

* "bgsound", "link", "meta", "style", "title", "blink", "xml" etc.</li>

* <li>javascript:/vbscript:/about: etc. protocols</li>

* <li>expression/behavior etc. in styles</li>
|

* <li>any other active content</li>
