268* months and years.</p>
269* <p>To construct the placeholder for the calendar widget, the code is as
270* follows:
271*       <xmp>
272*               <div id="cal1Container"></div>

282                                                                MM/DD/YYYY-MM/DD/YYYY. Month/day combinations are defined using MM/DD.
