Can someone answer if these will pass the new SC

<label>First Name<input ...></label>

The AccName would supply the purpose


<input aria-describedby="p1" ...></label>
<span id="p1" class="offscreen">credit card</span>

the AccDescription supplies the purpose

I think it should... and I think mapping AT should be able to map it. This
is what understood during a call between Lisa, John, me and a couple of
others early on as we were trying to find a way forward...
