Menu
Just covered out some strage specs regarding ARIA roles. Why does ul have ARIA role menu but menuitem is forbidden for li?
I would like to describe a navigation bar using ul, li and HTML5's nav element in combination with the ARIA roles navigation, menu and menuitem.
<!DOCTYPE html>
<html>
<head><title>ARIA role bug?</title></head>
<body>
<nav role="navigation">
<ul role="menu">
<li role="menuitem"><a href="http://example.com/">example.com</a></li>
</ul>
</nav>
</body>
</html>
W3's HTML5 validator nag me here:
Bad value menuitem for attribute role on element li.

The document role is for focusable content within complex composite widgets or applications for which assistive technologies can switch reading context back to a reading mode. ARIA document-structure roles are used to provide a structural description for a section of content.
The ARIA img role can be used to identify multiple elements inside page content that should be considered as a single image. These elements could be images, code snippets, text, emojis, or other content that can be combined to deliver information in a visual manner.
Accessible Rich Internet Applications ( ARIA ) is a set of roles and attributes that define ways to make web content and web applications (especially those developed with JavaScript) more accessible to people with disabilities.
The menu role is a type of composite widget that offers a list of choices to the user.
Jukka is incorrect here. The W3C validator does not check against the WHATWG LS, instead it checks against the W3C HTML specification. The W3C HTML spec is the authoritative source for conformance checking requirements for the W3C Validator.
In regards to menuitem not being allowed as per the HTML spec, I believe this is a bug. And as such I have filed a bug. It is now in my bug queue to be resolved.
I have filed a bug against the W3C validator and wai-aria in HTML doc as well. Until such times the validator is fixed, I suggest you use the roles as per the WAI-ARIA spec and ignore the validator.
addendum:
I looked back at history of ARIA integration into HTML could not find any reason why menuitem was not allowed, so believe it was an oversight. I fixed and resolved the bug I referenced above.
