Is the IRenderer interface not exactly the same
like the IContentProvider?

Does it provide an additional __call__ method?
Or only  __call__ method?

It smells to me that we should name it to something like
IProvider if it's a base for our IContentProvider or
IXHTMLProvider if it provides XHTML based on z3c.pt

I preferre anything with the word provider instead of
renderer.

yes, this package must be a zope.* package.
Then we could move the ITerms interface to this
package too rather then add a new one like zope.term.
