[VE][html5] Issue with menubar and child menu item's

I’m not sure if this is an issue with my code or the validator.  I thought
that if you have an element with role=menubar you could have children that
are role=menuitem, but the validator is saying its invalid, and that the
parent has to be role=menu.  Is there something I’m missing in my markup? Is
this a validator issue?  Markup is similar to this:



<ul role="menubar"><li class="first" role="menuitem"><a
href="/">Home</a></li><li role="menuitem">



Etc…

Thanks,

Paul
