Yes. I forgot to mention that. And, I realized just after posting the 
email to the list that calling a method "getattr" is asking for trouble :-)

Actually, my workaround doesn't work except in the most trivial cases.
My code was making more errors as Zope tried to look up the _ variable 
via __getitem__ and thus via my PythonScript.

I've ended up using a dtml-if to choose whether to use a <dtml-with 
stuff mapping> block or just a plain <dtml-with stuff> block.

I'd still like to know why a Dataskin from a specialist is behaving 
differently from one in the ZODB in this respect.
