[Zope-CMF] CMFTopic problem, passing args in DTML, or just brain damage?

Interesting!  Where do I look in the source for background?  And, do you
have a suggestion of how I could do this from a DTML method?  I tried
<OBJECT data="/list?Subject=something"></OBJECT>, that didn't work...

The background of this is, I'm interested in using CMFTopic as a sort of
tree to get lists of stuff on the site, progressively refined.  But I have a
group of subjects which act as 'modifiers' so they are at the leaves of
every branch.  A pain to construct, so I though I could leave off the leaves
and use that question mark business... which works great from a URL.

Otherwise, I'm about to give up on CMFTopic for this purpose, and just do my
own catalog queries.  Not a big deal, really... news_box is the example I'm
following.

Sorry, I mistyped - I used "list.topic_view(_.None,_)", and variations.
