  <pre><code>&lt;definition name="myapp.homepage.body" template="/layouts/three_rows.jsp"&gt;
    &lt;put-attribute name="one" value="/tiles/headlines.jsp" /&gt;
    &lt;put-attribute name="two" value="/tiles/topics.jsp" /&gt;
    &lt;put-attribute name="one" value="/tiles/comments.jsp" /&gt;
  &lt;/definition&gt;
  
  &lt;definition name="myapp.homepage" template="/layouts/classic.jsp"&gt;
    &lt;put-attribute name="title" value="Tiles tutorial homepage" /&gt;
    &lt;put-attribute name="header" value="/tiles/banner.jsp" /&gt;
    &lt;put-attribute name="menu" value="/tiles/common_menu.jsp" /&gt;
    &lt;put-attribute name="body" value="myapp.homepage.body" /&gt;
    &lt;put-attribute name="footer" value="/tiles/credits.jsp" /&gt;
  &lt;/definition&gt;
  </code></pre>
  
  <p>I need to extend <code>myapp.homepage</code> and in that extended definition I need to add another attribute to  <code>myapp.homepage.body</code> . Hope it make sense.</p>
