You define your format.

wp_list_comments( ... , 'myformat', ...);

// create a callback
if( function_exists( 'myformat_comment' ) )
{
    $args['format'] = 'myformat';
    $args['callback'] = 'myformat_comment';
}

Within a new function.

function myformat_comment( $comment, $depth, $args ){}

based on:
