An IUccContact instance is a type-specific category instance. A contact instance is created when a contact's IUccCategoryInstance is created. This interface can be queried from an IUccCategoryInstance object. A contact is a user whose presence and other category instances the local user has subscribed to. In contrast a subscriber (IUccSubscriber) is a user who is subscribing to the presence and other category instances of the local user.
