Pages do not validate as correct anymore with the W3C parser.

The checkup for HTLM5.

They have transferred from the experimental controller to a more definitive controller.

The fault has for example a connection with li and id="imMnMnNode *" class="imMnMn* li id="imMnMnNode14"

14 can be any other number

 they say:

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

Every page has many faults according to their checkup. (more than 40) -- The cause can be one little fault that causes other happenings of course...

Yesterday everything in htlm5 was allright and ONE day later they announced faults in htlm5. --- How come ??  Every page does validate with mistakes with id="imMnMnNode and a li missing some <i>aria-..... </i></p> <p><i>I can't sing aria's</i> and <i>li</i> is missing them.</p> <p>My htlm5 code was checked as allright at first .</p> <p>Everything works allright, but if there are faults -  <span class="underline">or if that aria-stuff isn't really needed -  I can't control my own htlm plugins anymore...

I looked on the internet and I saw some other people with the same happening....
