Didn't you speak of a Python Script originally?

The "getattr" is for the Python Script.

In DTML you have either:

	<dtml-with expr="_.getitem(_['sequence-item'])">

if your object is already on the DTML namespace
or

	<dtml-with expr="_.getattr(obj,_['sequence-item'])"

if you are interested in the attributes of "obj".
