I don't think we should flatten the hierarchy totally, just like so:

[menubar]
-[menubar.menu1]  
--[menubar.menu1.menuitem1]
--[menubar.menu1.menuitem2]
--[menubar.menu1.submenu(3)]
---[menubar.menu1.submenu.menuitem1]
---[menubar.menu1.submenu.menuitem2]
-[menu2] 
...

Why not expose all the submenu-items as children instead?  This
(proposal for one child that then has more menuitem children) seems
like a useless indirection.
