       I will appreciate any type of feedback (include your opinions and/or suggestions). ;-P

       The DTD parser was based on XML-DTDParser-1.7 by Jenda@Krynicky.czhttp://Jenda.Krynicky.cz

       itself.

         use XML::Smart::DTD ;

         my $dtd = XML::Smart::DTD->new('some.dtd') ;

         if ( $dtd->child_exists('tag1','subtag1') ) {
         ...
         }

         use Data::Dumper ;
         print Dumper( $dtd->tree ) ;
