   Nothing. You do it all right, but you forgot that Documents and Methods
have different namespace rules. A Method does not have its own namespace,
so objectValues is applied to its (the Method's) container.
   But a Document has its own namespace, so objectValues is applied to the
Document itself! And there is no subobjects to list by objectValues, so you
got nothing.
   Inside DTML Document you would write
<dtml-in expr="PARENTS[-1].objectValues('DTML Document')">
   thus listing objects in Document's parent (e.i. its container).
