13     * DynUnion objects support the manipulation of IDL unions.
14     * A union can have only two valid current positions:
15     * <UL>
16     * <LI>zero, which denotes the discriminator
17     * <LI>one, which denotes the active member
18     * </UL>
19     * The component_count value for a union depends on the current discriminator:
20     * it is 2 for a union whose discriminator indicates a named member, and 1 otherwise.
