CORBA26 — IDL out parameters can't map to EJB?

Section 8.3.1 says "The signatures of the CORBA component operations are mapped to signatures of EJB remote interface methods following the IDL to Java mapping rules."

As far as I can see, this only works if the IDL signature has no out or inout parameters. The Holder classes for out and inout parameters cannot be used in an EJB interface signature because they need not be Serializable, which breaks the rules for an RMI compliant class. Even if they could the EJB stubs and skeletons would not implement their special return value behavior without modifications to the EJB spec.

Someone please tell me I've missed something!
