[Zope] DTML Container?

[Steve Spicklemire]

Hi Mike,

   Hmmm.. how about just letting each instance of your
ObjectManagerish ZClass contain a "DTML Method" called
story_dtml or something. Then the index_html method of
the Zclass could (among other things possibly..) call

<dtml-var story_dtml>

which can then us all the tags your're talking about freely?

more soon I'm sure... ;-)
