Note – $, $$All features that have been added after CORBA 2.3 have been marked as optional in GIOP 1.2. These features cannot
be compulsory in GIOP 1.2 since there is no way to incorporate them in deployed implementations of 1.2. However, in order
to have the additional features of CORBA 2.4 work properly these optional features must be supported by the GIOP 1.2 implementation
connecting CORBA 2.4$ or CORBA 2.5 or 2.6$$ ORBs.
