Here is how that would be done using the current proposed model:

  <menubar id="sample-menubar">
   <menu label="Application Menu">
    <select>
      <option value="" selected> Application Menu </option>
      <optgroup label="File">
        <optgroup label="New">
          <option label="Document">New - Document</option>
          <option label="Template">New - Template</option>
          <optgroup label="Web Application">
            <option label="Web Forms 2.0"> New - WebApp - WF2 </option>
            <option label="XForms 2.0"> New - WebApp - XForms 2.0 </option>
            <option label="SVG 1.2"> New - WebApp - SVG 1.2 </option>
            <option label="XAML"> New - WebApp - XAML </option>
            <option label="XUL"> New - WebApp - XUL </option>
          </optgroup>
        </optgroup>
        <option label="Open">Open</option>
        <option label="Save">Save</option>
        <option value="" disabled>-----</option>
        <option label="Exit">Exit</option>
      </optgroup>
      <optgroup label="Edit">
        <option label="Undo">Undo</option>
        <option label="Redo">Redo</option>
      </optgroup>
      <option label="Help">Help</option>
    </select>
   </menu>
  </menubar>

(In both cases, appropriate logic would have to be included in the
<select> element's onchange="" attribute to actually make anything
happen.)

The thing I'm still not really sure about is the whole thing of how to
make it look like a menu bar when it is used inline, instead of being
used in the actual menu bar.

At the moment that requires the use of <a> elements, so that the top
would look like this:

  <menubar>
   <a href="#sample-menubar">Application Menu</a>
   <menu id="sample-menubar">
    <select>
      <option value="" selected> Application Menu </option>
      <optgroup label="File">

...which is rather poor. Suggestions welcome.

I thought of making it just work with:

  <menubar>
   <menu label="Application Menu">
    <select>
      <option value="" selected> Application Menu </option>

...but I couldn't work out how to define it so that the CSS and DOM
Events models would work sanely with that. It would need CSS3 Content
type stuff at least. (Or XBL, I guess.)

In the proposed model, this is achieved by using a <menubar> element
instead of an attribute. This allows other elements (such as links,
buttons, etc) to be used instead of a <select> depending on exactly
what behaviour is desired.

Once you know it's a menu bar, none of this is really necessary.

There have been a lot of requests for nested OPTGROUPs, so I'm
thinking maybe we should just allow them.

Instead of type="dummy" the current proposal says that value="" does
this.
