Right, but annotations are still content in their own right. And we fire 
events that are specific to annotations all the time, for example in workflow 
instances.

It does not have to be like a container. It could be:

IAnnotationAdded(object, key, annotation)

Right now, I have no hook that allows me to do something else after I added a 
new annotation for an object. Events are designed to allow expanding the 
system without touching the original code. And that's what I want to do. We 
do it in all the other packages of Zope 3.
