As my first sentence should have told you, I'm by no means an expert or
even an advanced user of formlib. So vocabularies were just what I found
working for me quite easily.

I know there have been some talk on the Zope3 mailing list a while back
that vocabularies are going to be deprecated in favor of sources
someday, but it also sounded like sources are not yet as well documented
and easy to use.

If you could enlighten us how to use sources instead for one of the
vocabularies currently in plone.app.vocabularies that would be awesome.

Thx,
Hanno
