And as always happens when you actually need something to work for a
project, as we did, the documentation trails the implementation.
We've implemented some advanced widgets using the vocabulary support
for customer projects, and the foundation is holding up well.

So the foundation (the vocabulary interfaces and the schema fields,
and way widgets are assembled) is pretty solid.  The specific widgets
in the Zope 3 core have seen some use, though not as much as the
core.  Widgets for the bag and set fields really aren't ready; those
fields are there for completeness of the model, but we've had no
concrete requirements for them, so widget needs haven't been explored
as much.  The base edit widgets for list and unique-list fields could
also stand some work, but we've a better idea how those should work
since we've implemented solid examples to meet customer requirements.

Definately!  Please let us know how you make out with this.
