Product

axe-core

Feature Description

A new authors MUST to the ARIA spec: w3c/aria#2500

It is all in the name :)

For example, this should error:

<div role=tablist>
  <button role=tab aria-selected=false>foo</button>
  <button role=tab aria-selected=true>bar</button>
</div>

<article>
  bar content goes here
</article>

@spectranaut When are you expecting to see this in rec? There is a lot of stuff in ARIA 1.3 that hasn't gone through public review yet. I'm less concerned about adding exceptions and clarifications based on editor drafts, but adding new requirements before they've gone through public review is a little more difficult to argue.

Good question @WilcoFiers . We are moving ARIA towards a living standard, but right now we are in between a versioned and living standard process. I just wrote you an email to suggest a time to meet to get your feedback on our procedural changes and how they effect axe core :)
