Per-objref data includes the (protocol-specific) Profile, which is handled by placing it into a subclass of this type along with data that may be used in protocol-specific caching schemes. The type ID (the data specified by CORBA 2.0 that gets exposed "on the wire", and in stringified objrefs) is held by this module. The stub APIs are member functions of this type.
