Yes you are right, that was the reason I didn't define the 
__init__ method in the interface. But I still think a 
IPagelet isn't a IContentProvider by default. Of corse 
another class can be defined as IContentProvider and IPagelet. 
Such a class whould then provide a different __init__ method 
then the pagelet does right now.

Thomas;
Should we implement a z3c.form/z3c.pagelet package?
There we could support z3c.form base classes built
up on pagelets.

Probably called z3c.formpagelet which contains
IPageletForm, IPageletAddForm etc.
