SVG lives in its own namespace. Hence, this working group cannot add 
@longdesc to <svg>. What we could do, is to extend @longdesc to any 
element with role='img':

<div role=img longdesc=link ><svg/></div>
<object role=img data=svg.svg type='image/svg+xml' longdesc=link 
></object>

Looking squarely at Laura's Change Proposal: Is there any reason not to 
expand it - before we go to a poll/survey - to cover any element where 
the author has given it role='img'?

I mean: If we want to put the horse *before* the cart?

It would be futile to ask the chairs to consider @longdesc a second 
time, for other use cases, if we are not able to the the single, most 
logical step.

An element with role=img is - from an AT user's point of view - 
entirely closed. It is only the info that the author has placed there - 
in @title, @aria-label, @alt etc - specifically for that purpose, that 
makes a role=img element perceivable to that user group.

Laura, Janina, Chairs?
