[Zope-CMF] How to select"published" documents with discussions "enabled."

[Troy Farrell]

Welcome new zope user.

When you run these queries against the portal_catalog, you can only 
query variables that are stored in the catalog.  In CMFDefault (I'm not 
a plone user), there are no "discussion" related variables cataloged. 
You would need each item to have a function that verified that the item 
was discussable by calling the discussion tool's isDiscussionAllowedFor:

context.portal_discussion.isDiscussionAllowedFor(item)
