  * {@link org.springframework.beans.factory.xml.BeanDefinitionParser} that parses the {@code annotated-controllers} element to setup
  * <code>@Controller</code> configuration in a Spring MVC web application.
- * 
+ * <p>
+ * Responsible for:
+ * <ol>
+ * <li>Registering a DefaultAnnotationHandlerMapping bean for mapping HTTP Servlet Requests to @Controller methods using @RequestMapping annotations.
+ * <li>Registering a AnnotationMethodHandlerAdapter bean for invoking annotated @Controller methods.
+ * Will configure the HandlerAdapter's <code>webBindingInitializer</code> property for centrally configuring @Controller DataBinder instances:
+ * <ul>
+ * <li>Configures the conversionService to be the bean named <code>conversionService</code> if such a bean exists,
+ * otherwise defaults to a fresh {@link ConversionService} instance created by the default {@link FormattingConversionServiceFactoryBean}.
+ * <li>Configures the validator to be the bean named <code>validator</code> if such a bean exists,
+ * otherwise defaults to a fresh {@link Validator} instance created by the default {@link LocalValidatorFactoryBean} <i>if the JSR-303 API is present in the classpath.
+ * </ul>
