We can determine the container, but we can't reliably the name:

 >>> class Foo:
...    def eeek(self): pass
...    oook = eeek

 >>> Foo().oook.__name__
'eeek'

No can do.  I'll note that validateValue is hardly every used, at least
in the Zope CVS.

We really *do* need to refactor this stuff. What we're doing now is a stop-gap
measure. Before releasing 2.8, I want to try to design what we want in 2.9
and have 2.8 include warnings and other guidence that will help people get ready
for 2.9.
