Comment:

 I see your point, but it would still be nice if the ''start_el'' function
 could get this argument passed on by default, because now it only knows of
 this argument if the ''$args'' object passed to ''display_element'' is an
 array.. or am I missing something something there? I mean,
 ''$children_elements'' is not available to ''start_el'' in some way is it?

 for now I resorted to adding the has_children argument to the $args object
 if it is an object (in ''display_element''):

 {{{
                 //display this element
                 if ( is_array( $args[0] ) )
                         $args[0]['has_children'] = ! empty(
 $children_elements[$element->$id_field] );
                 else
                         $args[0]->has_children = ! empty(
 $children_elements[$element->$id_field] );

                 $cb_args = array_merge( array(&$output, $element, $depth),
 $args);
 }}}
