title: multiple <c:when> inside <c:choose>
body: <p>I am just wondering whether the below code is valid?</p>
  
  <pre><code>&lt;c:choose&gt;
      &lt;c:when test="${empty example1}"&gt;
      &lt;/c:when&gt;
      &lt;c:when test="${empty example2}"&gt;
      &lt;/c:when&gt;
      &lt;c:otherwise&gt;
      &lt;/c:otherwise&gt;              
  &lt;/c:choose&gt;
  </code></pre>
