/**
* Convenience extension of {@link DefaultListableBeanFactory} that reads bean definitions
* from an XML document. Delegates to {@link XmlBeanDefinitionReader} underneath; effectively
* equivalent to using an XmlBeanDefinitionReader with a DefaultListableBeanFactory.
*
* The structure, element and attribute names of the required XML document
* are hard-coded in this class. (Of course a transform could be run if necessary
* to produce this format). "beans" doesn't need to be the root element of the XML
* document: This class will parse all bean definition elements in the XML file.
*
*
This class registers each bean definition with the {@link DefaultListableBeanFactory}
* superclass, and relies on the latter's implementation of the {@link BeanFactory} interface.
* It supports singletons, prototypes, and references to either of these kinds of bean.
* See {@code "spring-beans-3.x.xsd"} (or historically, {@code "spring-beans-2.0.dtd"}) for
* details on options and configuration style.
*
*
For advanced needs, consider using a {@link DefaultListableBeanFactory} with
* an {@link XmlBeanDefinitionReader}. The latter allows for reading from multiple XML
* resources and is highly configurable in its actual XML parsing behavior.
