Remarks

On receipt of this notification the snap-in should enumerate the children (sub-containers only) of the specified scope item, if any, using IConsoleNameSpace methods. Subsequently, if a new item is added to or deleted from this scope object through some external means, then that item should also be added to or deleted from the console's namespace using IConsoleNameSpace methods.
