/**
* {@link org.springframework.beans.factory.xml.BeanDefinitionParser}
* implementation that allows users to easily configure all the infrastructure
* beans required to enable annotation-driven transaction demarcation.
*
* By default, all proxies are created as JDK proxies. This may cause some
* problems if you are injecting objects as concrete classes rather than
* interfaces. To overcome this restriction you can set the
* 'proxy-target-class' attribute to 'true', which
* will result in class-based proxies being created.
