This calls (renders) the DTML object

this does not call (render) the DTML object but means the object itself.
The using environment converts the DTML object into a string by
calling "str". "str(dtmlObject)" returns the object's source -- html quoted.


When you are using Python syntax ("expr" attribute),
you must yourself take care of calling the object (it
happens by magic when you use the "name" attribute (no Python syntax)).

Note, that calling DTML objects yourself has a caveat: you must
pass the two positional arguments "None, _" (in order not
to loose the DTML namespace).
