Very cool :).  Two feature requests are:

1. Allow a data handler like the "DataHandler" shown in the announe for
2Simple.  Since SAX is about event processing, it makes sense to be able
to fire off events (sub calls) when Simple builds an object (see
examples below).

2. Allow a that handler to reemit the object as a new XML document via
SAX, sorta like this:

    my $h = XML::Handler::Foo-> new();

    my $xp = XML::Simple-> new(
        Handler =>  $h,
        DataHandler =>  sub {
            my ( $simple, $ref ) = @_;
            
            ....do something to / with $ref-> ...

            $simple-> XMLOut( $ref );
        },
    );

    $p = XML::SAX::ParserFactory-> parser( Handler => $xp );

That would be quite powerful.  Hmmm, if you provide a set_handler()
method like XML::SAX::Base's (assuming you're not already subclassing it
to leverage its various event passing features), then this becomes a
neat way to transmogrify record oriented XML:

    ByRecord(
        XML::Simple-> new(
            DataHandler =>  sub {
            my ( $simple, $ref ) = @_;
            
            ....do something to / with $ref-> ...

            $simple-> XMLOut( $ref );
            },
        ),
        \*STDOUT
    )-> parse( \*STDIN );

or plain ol' XML:

    Pipeline(
        XML::Simple-> new(
            DataHandler =>  sub {
            my ( $simple, $ref ) = @_;
            
            ....do something to / with $ref-> ...

            $simple-> XMLOut( $ref );
            },
        ),
        \*STDOUT
    )-> parse( \*STDIN );

I'd love to retire XML::Handler::2Simple in favor of the forthcoming
XML::Simple.

Sincerely yours in feeping creaturitus,
