title: logging from inside dataweave
body: <p>Just like we use  </p>
  
  <pre><code>&lt;xsl:message&gt; 
  </code></pre>
  
  <p>inside XSL transformer and </p>
  
  <pre><code>system.out.println
  </code></pre>
  
  <p>for datamapper, do we have any logging mechanism for dataweave ? If not a direct component, do we have any other alternate mechanisms to achieve logging from inside dataweave ?</p>
