## NAME
    [XML::LibXML::Dtd] - [XML::LibXML] DTD Handling

## SYNOPSIS
      use [XML::LibXML];

      $dtd = [XML::LibXML::Dtd]->new($public_id, $system_id);
      $dtd = [XML::LibXML::Dtd]->parse_string($dtd_str);
      $publicId = $dtd->getName();
      $publicId = $dtd->publicId();
      $systemId = $dtd->systemId();

## 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 [XML::LibXML::Node], so all the methods
    available to nodes (particularly toString()) are available to Dtd
    objects.

## METHODS
    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);

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

        The same as new() above, except you can parse a DTD from a string.
        Note that parsing from string may fail if the DTD contains external
        parametric-entity references with relative URLs.

    getName
          $publicId = $dtd->getName();

        Returns the name of DTD; i.e., the name immediately following the
        DOCTYPE keyword.

    publicId
          $publicId = $dtd->publicId();

        Returns the public identifier of the external subset.

    systemId
          $systemId = $dtd->systemId();

        Returns the system identifier of the external subset.
