Object Sharing Between Scenes

It is possible within MHEG-5 to share objects between some or all scenes of an application. As an example, this can be used to have variables retain their value over scene changes, or to have an audio stream play on across a scene change. Shared objects are alway contained in an Application object. Since there is always exactly one Application object running whenever a scene is running, the objects contained in an application object are visible to each of its scenes.
