Yes, it does.  You can have multiple database sections
and database sections can now have a name.  The databases
are registered as utilities and participate in a ZODB multidatabase.
The first database defined is used as the root database.

Zope 3 doesn't support mounting, but the same functionality
is mostly trivially obtained using the ZODB multi-database APIs.
