22  * <code>NamespaceHandler</code> allowing for the configuration of
23  * declarative transaction management using either XML or using annotations.
24  *
25  * This namespace handler is the central piece of functionality in the
26  * Spring 2 transaction management facilities and offers two appraoched
27  * to declaratively manage transactions.
28  *
29  * One approach uses transaction semantics defined in XML using the
30  * <code>&lt;tx:advice&gt;</code> elements, the other uses annotations
31  * in combination with the <code>&lt;tx:annotation-driven&gt;</code> element.
32  * Both approached are detailed to great extent in the Spring reference manual.
