/**
 * A panel is a reusable component that holds markup and other components.
 * 
 * Whereas WebMarkupContainer is an inline container like
 * 
 * 
 *  ...
 *  <span wicket:id="xxx">
 *    <span wicket:id="mylabel">My label</span>
 *    ....
 *  </span>
 *  ...
 * 
 * 
 * a Panel has its own associated markup file and the container content is taken from that file,
 * like:
 * 
 *  *  <span wicket:id="mypanel"/>
 * 
 *  TestPanel.html
 *  <wicket:panel>
 *    <span wicket:id="mylabel">My label</span>
 *    ....
 *  </wicket:panel>
