My comment was intended as: we should wait to break current behavior, 
until HTML6. If you want to consider it like breaking a bone to reset 
it, that's the idea.
The current situation of position, visibility: hidden and display: none 
is well tested, and I am certainly being conservative in my position of 
altering core CSS architecture.

As I understand it, @hidden is a shortcut for display: none, in 
implementation and markup and may be implemented through the css 
selector: [hidden] { display: none; }.

I'm concerned about the structural problems of altering the CSSOM 
behavior display: none.

I'm concerned that encouraging display: none for perceivable content may 
lead to a digital divide for users of older browsers and ATs.

It's certainly possible for @hidden to be decoupled from display: none, 
I don't know what kind of compatibility fallout we'd see.

My objection is that altering display: none may break some strong 
precedents and long standing practices and that @hidden may mean a 
distinction between sighted and non-sighted interfaces. The language 
itself is discriminatory.

While we do say "hidden" or "display"; the effect of those two is very 
specific and technical it's about the side-effects of the object, not 
about visibility. Altering @hidden may make it about visibility.

I have no objections about aria-describedby -- I'd like to see more 
vendor discussion about flowto and describedby.
It's altering the semantics of @hidden that I'm concerned about. I'm 
also concerned about the long-lasting tug of war to maintain <img 

Those are three separate issues, that weave in and out of this thread. 
They're connected, because they're part of your proposal. You're trying 
to work with those semantics, and I seem to be rather immovable on 
@hidden and @longdesc.
I think there's a lot of good that can come from focusing on ARIA flow. 
But right now, we're looking at two attributes that I'd rather have left
