22   * Extension of the {@link org.springframework.transaction.PlatformTransactionManager}
23   * interface, indicating a native resource transaction manager, operating on a single
24   * target resource. Such transaction managers differ from JTA transaction managers in
25   * that they do not use XA transaction enlistment for an open number of resources but
26   * rather focus on leveraging the native power and simplicity of a single target resource.
27   *
28   * <p>This interface is mainly used for abstract introspection of a transaction manager,
29   * giving clients a hint on what kind of transaction manager they have been given
30   * and on what concrete resource the transaction manager is operating on.
