   * lazily the next time the value is requested. All bindings and properties in
   * this library support lazy evaluation.
   * <p>
   * An {@code ObservableValue} generates two types of events: change events and
   * invalidation events. A change event indicates that the value has changed. An
!  * invalidation event is generated, if the current value is not valid anymore.
!  * This distinction becomes important, if the {@code ObservableValue} supports
   * lazy evaluation, because for a lazily evaluated value one does not know if an
   * invalid value really has changed until it is recomputed. For this reason,
   * generating change events requires eager evaluation while invalidation events
   * can be generated for eager and lazy implementations.
