Update of /cvs-repository/Zope3/src/zope/app/utilities
In directory cvs.zope.org:/tmp/cvs-serv16509

Modified Files:
      Tag: schema_utility_persistence
	schema.py 
Log Message:
This implementation violates a private variable of interfaces. We need
to take a step back and think about the mutability of interfaces.
There is code that counts on interfaces being immutable, in large
part, for caching purposes.  Persistent interfaces already violate
this assumption.
