title: how do i set value of a Jaxb XMLelement?
body: <p>my question is: from the <code>xml</code> scheme :</p>
  
  <pre><code>&lt;topnode&gt;
      topNodeValue
     &lt;bottomnode/&gt; 
  &lt;/topnode&gt;
  </code></pre>
  
  <p>generated class with Jaxb looks like </p>
  
  <pre><code>class topnode {
      List&lt;bottomnode&gt; bottomnodeList;
  }
  </code></pre>
  
  <p>Which does not generate the value field to set value for topnode. </p>
  
  <p>How can I acheive this? Thanks.</p>
