The responsibility lies with the code making the change.  For
containers, the container code really is adding/renaming/removing, so
it can take care of the events.  For other objects, it can be hard to
tell what really constitutes a change for the purposes of the
application.  Not every attribute value might be considered part of
the application-level state; variables that simply represent caches
might not "count" for application purposes.  Only the application can
make these determinations.
