Dangerous flag in ObjectModes.
If you set it on an object and then perform a document.GetValue(treename), the object self destructs.
The flag seems to be intended for a particular internal use case, but does not seem to be set intentionally, ever. Either simply remove its functionality or safeguard it against outside use (in Serialize, OnValueChanged and the COM SetMode function).
