DTML methods do this, DTML documents do not. Think "Containment before
context" as a mantra. The only way to make a DTML Document act like it
is contained in a different container would be to use an external method
like so that rewrapped the document:

def rewrap(DTMLdoc, folder):
	"""Returns a document in the context of another folder"""
	return DTMLdoc.aq_base.__of__(folder)

I am not sure I would recommend this approach, however, as it goes
against the original DTML document design. What exactly are you trying
to do? I suspect an aspect of your design could be changed to alleviate
this.
