=head1 NAME
XML::DOM::Comment - An XML comment in XML::DOM
=head1 DESCRIPTION
XML::DOM::Comment extends L<XML::DOM::CharacterData> which extends
L<XML::DOM::Node>.
This node represents the content of a comment, i.e., all the characters
between the starting '<!--' and ending '-->'. Note that this is the
definition of a comment in XML, and, in practice, HTML, although some
HTML tools may implement the full SGML comment structure.
