HTML5 validator Errors:Element li is missing one or more of the following attributes: aria-checked, aria-expanded, aria-valuemax, aria-valuem

HTML 5 code that used pass without errors few days ago are now showing errors when I run it through W3C validator. Errors look something like this:

Element li is missing one or more of the following attributes: aria-checked, aria-expanded, aria-valuemax, aria-valuemin, aria-valuenow, aria-valuetext, role.

Any idea what's going on and how do I get rid of these errors?

Solution

  • This is an error of the W3C validator. It will be fixed.

    From http://lists.w3.org/Archives/Public/www-validator-cvs/2013Apr/0038.html:

    It's a validator issue. I made some updates today today to the ARIA support and it seems I likely introduced some unintended change. Thanks for the heads up. I will look into it and fix it as soon as possible and then respond here again.
