   Sort of. I'm leaning towards having all elements but <option> nested
in an <li> element, though. It just seems to have better semantics, and
it also allows you to use multiple elements to build a menu item, like
having an <img>, a <input type="checkbox"> and a <label> in the same
<li> to create a menu item with a checkbox and an icon.

   I fail to see what's wrong with using the activation of <menulabel>
to display menus. It allows handling of both menus that appear when you
press a "button" (which could be the default styling of <menulabel>
outside of a <menu>) and submenus within a menu:

| <menu>
|   <li>
|     <menulabel for="submenu">Submenu Label</menulabel>
|     <menu id="submenu"/>
|   </li>
| </menu>

   I believe you already state that <menu> elements are hidden until
activated when they have a label, so I don't see the problem.

   Should we be using <menu> for toolbars at all?
