Ben,

you'll find an explanation in your online-help,under
Zope Help->Api Reference->DTML Method
see the block about __call__.
Another source (highly recommended!) would be
the book Dieter Maurer is writing about zope at
http://www.handshake.de/~dieter/pyprojects/zope/book/book.html

esp chapter 3, paragraph 4.4.

cheers,
oliver
