Funny that you're asking this now that we discuss optimistic locking ;)

This flag indicates which attributes optimistic locking will check when
it is about to save changes: if value for attribute 'lastname' has
changed and 'usedForLocking' is set for tha attr., then under the
optimistic locking policy saveChanges() will raise; if the flag is
unset, the attribute will be silently overriden (for example, you
probably won't mark an object's timestamp as used for locking).

        Cheers,
