Both of these cases are indeed invalid IDL in CORBA 2.3, and omniidl
is right to complain about them. omniidl is intentionally very strict
about IDL conformance.

Section 3.2.3 of the 2.3 spec says "Identifiers which differ only in
case collide...". Section 3.15.2 says "The name of an interface,
value type, struct, ... may not be redefined within the immediate
scope of the interface, value type, struct,..."  These two sections
taken together cause your first error.

Section 3.2.4 says "Identifiers that collide with keywords (see
section 3.2.3) are illegal."  That causes your second error.

Cheers,

Duncan.
