I have a branch in CVS which makes TypeInformation objects also derive
from ActionProviderBase:

 <
http://cvs.zope.org/CMF/CMFCore/TypesTool.py?only_with_tag=tseaver-typeinfo_as_apb-branch>

I am planning to land this on the head soon (i.e., before the next
release).  It may have forward-compatibility issues, which is the major
blocker;  we would probably need to add a method to the TypesTool to
allow managers to upgrade their type objects in place.
