CORBA3 — IDL inheritance issue

The IDL specification is unclear about the names that can be used to
denote a base interface. Section 3.7.2 says

"Each <scoped_name> in an <interface_inheritance_spec> must denote a
previously defined interface."

but the word "denote" is not defined. In particular, is the following
legal?

interface I { };
typedef I J;
interface K : J { };

There is real IDL in use in the world that assumes that inheriting
from a typedef is permitted. I therefore suggest re-wording the part
of section 3.7.2 to be

"Each <scoped_name> in an <interface_inheritance_spec> must be the
name of a previously defined interface or an alias to a previously
defined interface."

A similar clarification is required in section 3.8.1.3, regarding
valuetype inheritance.

Good point. Incorporate the clarification
