    As a minimum, the implementation should return a TNotifierInfo instance

    describing the notifier parameters. A good implementation would be to set

    up a TNotifierInfo as a data member, and then to return it. This is because

    the same information is returned by Info().

    It is important to return from this function as soon as possible,

    The implementation of a derived class must make sure that Complete() is

    called on the RMessage2 object when the notifier is deactivated.
