/**
 * {@code NamespaceHandler} for the {@code aop} namespace.
 *
 * <p>Provides a {@link org.springframework.beans.factory.xml.BeanDefinitionParser} for the
 * {@code <aop:config>} tag. A {@code config} tag can include nested
 * {@code pointcut}, {@code advisor} and {@code aspect} tags.
 *
 * <p>The {@code pointcut} tag allows for creation of named
 * {@link AspectJExpressionPointcut} beans using a simple syntax:
 * <pre class="code">
 * &lt;aop:pointcut id=&quot;getNameCalls&quot; expression=&quot;execution(* *..ITestBean.getName(..))&quot;/&gt;
 * </pre>
 *
 * <p>Using the {@code advisor} tag you can configure an {@link org.springframework.aop.Advisor}
 * and have it applied to all relevant beans in you {@link org.springframework.beans.factory.BeanFactory}
 * automatically. The {@code advisor} tag supports both in-line and referenced
 * {@link org.springframework.aop.Pointcut Pointcuts}:
 *
 * <pre class="code">
 * &lt;aop:advisor id=&quot;getAgeAdvisor&quot;
 *     pointcut=&quot;execution(* *..ITestBean.getAge(..))&quot;
 *     advice-ref=&quot;getAgeCounter&quot;/&gt;
 *
 * &lt;aop:advisor id=&quot;getNameAdvisor&quot;
 *     pointcut-ref=&quot;getNameCalls&quot;
 *     advice-ref=&quot;getNameCounter&quot;/&gt;</pre>
