A5.6.2-4 [If a datastore transaction is begun, commit will write 
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.] 

A5.6.2-6 [If a datastore transaction is begun, rollback will not write 
any changes to the datastore.] 

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.] 

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. ]
