That is (almost) as it is supposed to be.

  In both cases, "objectItems" is looked up in the so called
  DTML namespace.

  If your object is a DTML document, then the (relevant) top level
  element is the document itself. If it is a DTML method,
  the method itself is not placed on the namespace, only
  its "client", i.e. the object for with the method has been
  called (usually, but not necessary a folder).

The only maybe a bit surprising thing is that a DTML document
seems to have an "objectItems" method which, of cause,
returns the empty sequence.

If you use "PARENTS[0]", then you get a similar result
to that, you would have with a DTML method.
