* Extension of the {@link org.springframework.transaction.PlatformTransactionManager}

* that they do not use XA transaction enlistment for an open number of resources but
* rather focus on leveraging the native power and simplicity of a single target resource.
*
* <p>This interface is mainly used for abstract introspection of a transaction manager,
* giving clients a hint on what kind of transaction manager they have been given
* and on what concrete resource the transaction manager is operating on.
