For once I think I might be able to answer something.  Through the ZMI these
choices should be verified automatically.  However, in your implementation
class you may want to consider the following:

class MyFruitClass(Persistent,Contained):
    
    fruit = FieldProperty(IMyFruitClass['fruit'])

I use this and have found it to work well(if I understand you).  I poached
this from Phillip's _Web Component Development_ book (section 5.2).
