A <sect2> element represents a second level section, always nested within a <sect1> . It may contain <sect3> sections, plus any other type of element supported by <sect1> with the exception of other <sect2> elements.
See <sect1> for full details of how to use the various section tags.
The title should be less prominent than that of <sect1> titles, but still very prominent. Bold text and large fonts are suggested.
