My variable is named "zone". The following Python-statement yields 1:

	return namespace.has_key("zone")

The following calls yield an error (each one):

	return namespace.items()
	return namespace.keys()
	return getattr(namespace, "zone")

I am using Zope-2.4.0

A second test with explicit calling:

DTML method:

<dtml-let xy="test">
<dtml-var expr="get_status_a(ns=_)">
</dtml-let>


python script get_status_a:

## Script (Python) "get_status_a"
##bind container=container
##bind context=context
##bind namespace=namespace
##bind script=script
##bind subpath=traverse_subpath
##parameters=ns
##title=

return ns.has_key("xy")   # OK, yields 1
return ns.xy              # ERROR:  Error Type: AttributeError, Error Value:
xy
