FYI. Vocabularies are a broken technologie. Sources are better as they
meet the background abstractions at the right points. The
zc.sourcefactory package makes it more accessible:

class MySource(zc.sourcefactory.basic.BasicSourceFactory):

   def getValues(self):
       theQuery = query.Eq(('workflow_catalog', 'workflow_state'),
       return query.query.Query().searchResults(theQuery)

   def getTitle(self, value):
       return value.title

   def getToken(self, value):
       # This method is optional and I just put it here to demonstrate
       # the sourcefactory.
       return value.iso_code

Then in your field definition you can do:

    country = Choice(title=u"Country", source=MySource())
