The service-side adds objects to the CAS that are in a typesystem that is not know on the client-side

During client initialization the client sends a getMeta request to all
remote services. The getMeta reply includes the service typesystem,
which is then integrated into the client typesystem. By definition
there are no out-of-typesystem types on the client side.

The only explanation for a such client-side error is that the service
typesystem was changed after the client was initialized, on at least
one service instance.
