If interface B inherits from interface A and class B implements
interface B; do I need to explicitly state that class B provides
interface A?
Concrete example:
class IElement(Interface):
value = Object(
schema=IDataValue,
title=_(uvalue),
description=_(uData value of

I believe not. In any case, implements, provides and such things are more
like indications of what is being supported by a class and they are not
enforced by runtime strictly.
I just tried following:

An instance of a class provides not only the interface the class
declares to implement, but also all base
The purpose of this question is related to an earlier question I had

Sorry, you got that backwards. Instances provide the interfaces their
class implements.
