Internal Program Version: HTML::Tagset  3.240.0.5.42.0

This module contains several data tables useful in various kinds of HTML
parsing operations.

Note that all tag names used are lowercase.

In the following documentation, a "hashset" is a hash being used as a set
-- the hash conveys that its keys are there, and the actual values
associated with the keys are not significant. (But what values are there,
are always true.)
