This looks good - with the ul added the W3 validator now reports

• Attribute aria-not-checked not allowed on element li at this point.
• Element li is missing required attribute aria-checked.
• An element with role=menuitemcheckbox must be contained in, or owned by, an element with role=menubar or role=menu.
