CORBA35 — Correction of CORBA specification (page 18-51)

>You write on page 18-51:
>In COM V2.0, interfaces can have single inheritance. However, as opposed to
>CORBA,
>there is a standard mechanism by which an object can have multiple interfaces
>(without
>an inheritance relationship between those interfaces) and by which clients can
>query
>for these at run-time. (It defines no common way to determine if two interface
>references refer to the same object, or to enumerate all the interfaces
>supported by an
>entity.)
>
>It's not right, that there's no common way to determine if two interface
>references refer to the same object. The IUnknown-Pointer of two different
>interfaces of the same object must be the same (object identity in COM).
