CORBA35 — Keyword identifiers (02)

Summary:
The Objects By Value (OBV) Specification (orbos/98-01-18) introduced
the concept of "keyword identifiers" in an effort to avoid breaking
existing IDL specifications.It allows IDL specifications that are simply unparseable. For example:

interface ValueBase {};
struct S

;

This is ambiguous because the compiler cannot know whether the type
of struct member "v" refers to the ValueBase interface or the
ValueBase keyword identifier.
