To me it doesn't feel right to store Address details in annotations as
company/person address is part of the actual data model and should be
included in the schema.  I would probably have something like addresses
Dict attribute as part of the ICompany and IPerson schema.  The
dictionary would have address type ('personal', 'work', 'home' etc.) as
the key, and values of the dictionary being IAddress type objects.
