you can do that by having your object be non-callable (or returning self
on __call__) and implementing __str__ where you can have access to the
REQUEST thru self.REQUEST. <dtml-with content> works as expected because
you're getting the object itself. To make <dtml-if content> work you
should implement __len__ (if your object implements sequence or mapping,
which it probably doesn't) or __nonzero__. Read the python docs for
details on the implementation of these methods.
