Did you try it and it did not work?

  As I understand it now, a DTML document does (almost) precisely
  what you want:

    It pushes "self.aq_explicit" onto the namespace stack.
    This means, it looks into itself (its properties and
    methods). It normally should not look into its physical parents
    because of the "aq_explicit". The "aq_explicit" disables
    automatic lookup of names in the "aq_parent".

  I know, that this method works only as you want it,
  when the DTML document is called directly from ZPublisher.
  If called indirectly, the document's parents are
  part of "aq_self" and not "aq_parent". Thus,
  "aq_explicit" does not prevent lookup there.

  If you are ready to use an external method for these
  indirect accesses, you can unwrap the document:

	   def unwrapContext(obj):
	     return getattr(obj,'aq_inner',obj)

  You use the result of this call as variant of the document
  for indirect calls.
