    I can't find anything about MENU nesting in the HTML 4.01 
specification. Is that in an earlier specification?

    Okay, that IS in the spec.[1]

    I support the nesting of <menu> elements for the purpose of having 
submenus. Though many zealots would object to submenus because it's 
considered poor UI, I believe there are often situations where submenus 
are difficult or impossible to avoid. Currently, there's nothing in WA1 
that would prevent nesting of <menu> elements, but there's nothing there 
to define how nested <menu> elements should be treated either. That 
needs to be fixed.

    Much of what we plan to do with menus is still up in the air, 
though. Feel free to contribute your own thoughts.
