CORBA35 — Section 7.3.10 Value Factories

Summary: Semantic of register_value_factory is not clear
What do applications should expect if a factory is already
registered for a given repositoryId?

The operation returns the previous factory. But it is not
clear whether it is overriden or not.

• When should register_factory be called ?
  I assume that this is after the ORB is initialized (since we
  need a pointer to the ORB). This means that initialization
  of "Component Libraries" is not trivial.
