/**
* {@code NamespaceHandler} allowing for the configuration of
* declarative transaction management using either XML or using annotations.
*
* This namespace handler is the central piece of functionality in the
* Spring transaction management facilities and offers two approaches
* to declaratively manage transactions.
*
*
One approach uses transaction semantics defined in XML using the
* {@code } elements, the other uses annotations
* in combination with the {@code } element.
* Both approached are detailed to great extent in the Spring reference manual.
