/**
 * 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.
 *
 * <p>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.
 *
 * <p>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.
 *
 * <p><b>For advanced needs, consider using a {@link DefaultListableBeanFactory} with
 * an {@link XmlBeanDefinitionReader}.</b> The latter allows for reading from multiple XML
 * resources and is highly configurable in its actual XML parsing behavior.
