=item TAG

something that has the form of an HTML tag

=item DECL

something that has the form of an SGML declaration

=item PI

something that has the form of an SGML processing instruction

=item DIRECTIVE

a Template Toolkit directive

=item COMMENT

something that has the form of an HTML comment
(and is not recognized as an HTML::Template directive)

=item UNKNOWN
