title: How to reuse "choice exception strategy" in mule
body: <p>In Mule flow how can I re-use choice-exception-stretegy across several flows?
  I tried the following, but it throws error when I run mule application.</p>
  
  <pre><code>&lt;mule ....&gt;
  &lt;choice-exception-strategy doc:name="My_exception_strategy"&gt;
        &lt;catch-exception-strategy when="exception.causedBy(java.net.SocketTimeoutException)"   doc:name="Strategy1"&gt;
        &lt;logger message="message 1" level="INFO" doc:name="Logger"/&gt;
        &lt;/catch-exception-strategy&gt;
        &lt;catch-exception-strategy when="exception.causedBy(java.lang.Throwable)" doc:name="Strategy2"&gt;
        &lt;logger message="message 2" level="INFO" doc:name="Logger"/&gt;
        &lt;/catch-exception-strategy&gt;
    &lt;/choice-exception-strategy&gt;
  
  &lt;flow name="Test1" doc:name="Test1" processingStrategy="synchronous"&gt;
      &lt;logger message="message 3" level="INFO" doc:name="Logger"/&gt;
      &lt;outbound-endpoint ref="myendpoint" doc:name="MyEndPoint"/&gt; 
      &lt;exception-strategy ref="My_exception_strategy" doc:name="Reference Exception Strategy"/&gt;
      &lt;set-variable variableName="somevalue" value="#[something]" doc:name="statusCode"/&gt;
  &lt;/flow&gt;
  &lt;/mule&gt;   
  </code></pre>
