Cleanup html code
The HTML code in the documentation is displaying as intended in the browsers tested but contains errors according to XHTML or HTML4/5.
E.g. these constructs recur several times:
<a name="ancor" /> - "a" cannot be an em[ty element . --> should be changed <a ...></a>
</p></li> - "p" can contain only phrasing content, no flow content (p, ul, div, ...) --> probably div should be used
