* information between {@link #begin(TransactionContext)} and

* Implementors may freely choose whether they support nested transactions. An
* example implementation supporting nested transactions is
* {@link DefaultTransactionProvider}, which implements such transactions using
* JDBC {@link Savepoint}s.
