This class is designed to represent all DocBook tags. It is intelligent enough to understand the <title> tag, and also the <refname> tag for as title for <refentry>
For most DocBook tags, the title is represented with a <title></title> tag pair. The <refentry> top-level tag is a little different. Instead of using <title></title>, phpDocumentor uses the contents of the <refname> tag in the <refnamediv> tag
