This notification is intended to allow
EOTemporaryGlobalIDs to be replaced with
the corresponding EOKeyGlobalIDs. In theory one could
interpret this as a mechanism to allow primary key
attributes to be mutable class properties. Even
though EOF also posts this notification in that case,
it fails to consistently propagate the new value through
relationships. GDL2 may attempt to correct
that shortcoming in the future, but it may have serious
performance implications.
