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