    A while ago, I suggested the use of <select> as a way of 
implementing menus. If nested <optgroup> elements were permitted, a 
select could easily be used to define a menu. It could be defined like this:

<select type="menu" label="File" accesskey="f">
   <optgroup label="New" accesskey="n">
     <option label="Document">Document</option>
     <option label="Template">Template</option>
     <optgroup label="Web Application">
       <option label="Web Forms 2.0">Web Forms 2.0</option>
       <option label="XForms 2.0">XForms 2.0</option>
       <option label="SVG 1.2">SVG 1.2</option>
       <option label="XAML">XAML</option>
       <option label="XUL">XUL</option>
     </optgroup>
   </optgroup>
   <option label="Open" accesskey="o">Open</option>
   <option label="Save" accesskey="s">Save</option>
   <option type="menuseparator" disabled>-----</option>
   <option label="Exit" accesskey="x">Exit</option>
</select>
