CORBA23 — Forward-Declared Interfaces

Summary: there just has been raging discussion on the OB list about forward-declared
interfaces. The words we have right now are inadequate. You could argue that the
interface is defined in the same "specification" here. However,
current IDL compilers (if they implmement the check at all) require
the interface to be defined in the same compilation unit as the
forward declaration.

Now, we could allow a forward-declared interface to not be defined in
the same compilation unit, but then, I think, we would have to very
carefully specify what sort of things I can do with the forward-declared
interface. (If we don"t do that, we"ll make separate compilation impossible
because the compiler doesn"t know the size of a forward-declared interface
nor its base interfaces.)

What"s the general feeling here? I think we could simple change "specification"
to "IDL source file" and be done with it. That"s the simple way out.
