=head1 HTML TAG GROUPS

The following groups can be disallowed or allowed as you choose. Some tags are
present in more than one group. In these cases, the tag must be present in
I<every> allowed group, or the tag will be removed.

=head2 everything

All HTML.

=head2 document

Markup that defines the basic structure of a document (e.g. html, head, body).

=head2 dynamic

Markup that specifies JavaScript or some other embedded format (SVG, Flash,
Java, etc.) Possibly dangerous.

=head2 misc

Usually seldom-used, typically-harmless HTML tags that specify special types
of inline text. (e.g. abbr, dd, span).
