Ok, So after some *major* hacking, i've realized that the 'md' passed
into the render() method of my dtml tag contains the namespace, and is
of type 'TemplateDict' which appears to contain a stack of
'MultiMapping's.  Weird.  Well, anyways, I just used the 'has_key' and
'getitem' methods to lookup my item.  The question now is how do I
create a new object in the current namespace?  It looks like the
TemplateDict is a read-only type of data structure.  Anybody?  TIA
