Ahh, of course, doh.
I guess there really is no way in Zope to distinguish between an object
which represents itself (ie is a leafnode) from those which represent
others -- for the simple reason that they are the same: the same code
and same inheritance trees are present in both. I'm going to have to
think about this a bit more.
