[public-html] <none>

Chairs, please see my reasoning in the quote from 14th of March, below, 
and answer the following question:

QUESTION: Can you give us a hint about how it would be evaluated if 
Lauras - or another - proposal promotes @longdesc for *any* element 
that have role=img, versus Laura's current proposal - which - though it 
also contains language which says that one could expand its use - 
allows it on the img element alone?

In particular: Would it necessarily become any simpler to expand 
@longdesc to other elements if HTML5 first allows it on img? Would it 
be *expected* that it then gets expanded? In earlier Decisions, ideas 
that were presented but not presented as The Change Proposal, have been 
dismissed.

In your original Decision, you mentioned that @longdesc in HTML4 is 
permitted on both iframes and img. Also, in the Decision and later, you 
have asked for justification for why only <img> should have @longdesc - 
which is what the proposals to make @longdesc conforming, have argued. 

Currently, there seems to be agreement amongst the @longdesc supporters 
that a long description link feature for more situations than <img> 
elements with the ARIA role of an 'img', is needed. And one way to 
justify the focus on img alone, could be the possibility of 
@aria-describedAT - in which case @longdesc on img alone, becomes more 
defendable. It could also be argued that <img> is a unique element that 
deserves some special casing.

The absolutely lowest fruit would be a CP that extends support to 
iframe: It ought to already be implemented and working, and iframe does 
sometimes act as an image. A little bit higher up, hangs the fruit 
called 'any element that has - or is given - role=img'. And close to 
that is <video> and poster image. Plus allowing it to describe any 
embedded content. The highest fruit is to allow it to describe 
'anything', regardless of the role of the element.
