Text in a documentation comment may use HTML markers for formatting, with
the exception that the specific markers <H1>, <H2>, <H3>, <H4>, <H5>, <H6>, and
<HR> are reserved for use by the documentation generator and should not be used
in the text. A complete description of HTML is available from the web site
http://www.w3.org/ and also through the Internet documentation database at
http://www.internic.net/, where the document "Hypertext Markup Language
-Version 2.0" by T. Berners-Lee and D. Connolly may be found as RFC1866.
