Used for view data persistence (ie. tree expanded states, scroll position, zoom level).

If set, it can be combined with the persistenceKeys of the parents to locate persistency data for this VisualElement in the EditorWindow's persistent data store. Not setting this key will disable persistence for this VisualElement. To get the fully derived key, call VisualElement.GetFullHierarchicalPersistenceKey.
