=head1 NAME

XML::LibXML::Dtd - XML::LibXML DTD Handling

=head1 SYNOPSIS

  $dtd = XML::LibXML::Dtd->new($public_id, $system_id)
  $dtd = XML::LibXML::Dtd->parse_string($dtd_str)


=head1 DESCRIPTION

This class holds a DTD. You may parse a DTD from either a string, or from an
external SYSTEM identifier.

No support is available as yet for parsing from a filehandle.

XML::LibXML::Dtd is a sub-class of Node, so all the methods available to nodes
(particularly toString()) are available to Dtd objects.

=item B<new>

  $dtd = XML::LibXML::Dtd->new($public_id, $system_id)

Parse a DTD from the system identifier, and return a DTD object that you can
pass to $doc->is_valid() or $doc->validate().

   my $dtd = XML::LibXML::Dtd->new(
                        "SOME // Public / ID / 1.0",
                        "test.dtd"
                                  );
   my $doc = XML::LibXML->new->parse_file("test.xml");
   $doc->validate($dtd);


=item B<parse_string>

  $dtd = XML::LibXML::Dtd->parse_string($dtd_str)

The same as new() above, except you can parse a DTD from a string.
