The Cobject class was originally created in order to provide classes that were not a subclass of Xobject and that did not have an ID attribute with an ID attribute. However, now that the INSERT operation in OPM returns the _oid of the newly-created object, the Cobject class serves to provide an optional ``displayName'' for database objects.
