The new PrefabDocument handles the Prefab and the Instance. This reduces the number of times the Instance has to be reloaded from the Prefab and keeps the entity ids stable between steps. The intention is for all the PrefabDocument to conceptually manipulate the Prefab DOM, although behind the scenes it will manipulate the Instance for now. The Instance should only be directly used in case the PrefabDocument doesn't provide the functionality yet.
