Does the real work. Needs to acquire locks if accessing nodes, depending on the value of locking. If run inside a transaction, needs to (a) add newly acquired locks to TransactionEntry's lock list, (b) add nodes that were created to TransactionEntry's node list and (c) create Modifications and add them to TransactionEntry's modification list and (d) create compensating modifications to undo the changes in case of a rollback

Parameters:

fqn -

data -

create_undo_ops - If true, undo operations will be created (default is true). Otherwise they will not be created (used by rollback()).
