 * the changes to the datastore with no checking as to the current state of the instances in the
 * datastore. That is, the changes made outside the transaction together with any changes made
 * inside the transaction will overwrite the current state of the datastore.]
 *
 * <p>A5.6.2-6 [If a datastore transaction is begun, rollback will not write any changes to the
 * datastore.]
 *
 * <p>A5.6.2-8 [If an optimistic transaction is begun, commit will write the changes to the
 * datastore after checking as to the current state of the instances in the datastore. The changes
 * made outside the transaction together with any changes made inside the transaction will update
 * the current state of the datastore if the version checking is successful.]
 *
 * <p>A5.6.2-10 [If an optimistic transaction is begun, rollback will not write any changes to the
 * datastore. The persistent-nontransactional-dirty instances will transition according to the
 * RestoreValues flag. ]
