The object class definition page lists the flags that are turned on for the object class. If the flag isn't listed, you can assume that the flag is turned off for that object class. Flag Description Container Flag Indicates whether the object can contain other objects. Turn the flag ON for those object classes that are designated as container classes. Leave the flag OFF for leaf object classes.
Effective Flag Indicates whether an object class is effective or noneffective.
Turn the flag ON for effective classes, or those classes that can be used both to provide definition and to create objects. Leave the flag OFF for classes which provide definition but cannot be used to create objects. Auxiliary Flag Indicates whether an object class is an auxiliary class. When this flag is turned on, NDS ignores the container and effective class flags. Turn the flag ON for auxiliary classes.
