Here's an except from my Python interactive interpreter:

 >>> import DocumentTemplate
 >>> my_dt=DocumentTemplate.HTML("""<dtml-var "1+a">""")
 >>> my_dt(None, {'a':4})
'5'

The object my_dt is callable, and takes the arguments (client, 
namespace). You can put a REQUEST in place of the simple dictionary I 
used above.

If you're trying this, make sure you have the PYTHONPATH environment 
variable set to /your/zope/directory/lib/python
