Steve, is that an implementation issue or a real blocker? Seems like
implementation to me.

Subject: Re: First draft of ARIA 1.1. "text" role
The main issue is that <img> is a void element. If image was like this:
<img> alt text </img>
we would not have a problem, we could just use role=presentation.
<img role="presentation"> alt text </img>
but that ship sailed long ago.

Marco, aria-labelledby or aria-label only takes the place of the contents
of an element if the role specifies that accessible name is from contents.
In the definition of role presentation, it is clear that span is redundant
with or equivalent to presentation.
Role presentation specifies that the accessible name comes from author.
So, based on this, aria-label on a span would "supplement" the content of
the span, not replace it.
The spec is silent about elements that don't have an implied aria role,
for example paragraph. I can not find anything in the spec that says what
should be done with an aria-label on a paragraph. There is probably some
phrase buried in there someplace that covers it.
On the other hand, consider list item, heading, button, and link. These
are examples of roles where the spec is clear that aria-label would
replace the content.
This is a sometimes useful but nonetheless dangerous aspect of ARIA, and I
have, like probably most of us screen reader users, experienced its
unintended consequences to devistating effect at times.

Subject: Re: First draft of ARIA 1.1. "text" role
Well if I remember correctly, it has always been said that if something
has an aria-label* construct, it should be prioritized over any normal
text that might also be there. If some AT vendors don't honor that, or
only honor it if some random selection tells it to, that's not a problem
of the ARIA spec and doesn't need an extra role. If an extra would be what
is needed to make it more palpable to somebody, then we do have a problem,
but not a technical one, but an evangelism one. Because, turning things on
its head, a role does not necessitate an aria-label* construct. In other
words, an aria-label* construct can exist without a role, and should be
treated by ATs accordingly. Likewise, the presence of a role does not mean
there always has to be an aria-label* construct, and ATs should not stop
looking for other means of a name just because there is a role set.
If we suddenly started to require a role always be present if an
aria-label* construct is, and vice versa, it defeats the premise that ARIA
is an addition where the host language falls short. Because if the host
language already provides the correct semantics for a role, which it does
in your example, or for a given widget role, the mechanics of the host
language provide the correct name already, there is no need to use the
other respectively. It would only over-complicate things unnecessarily and
lead to code that is bigger than it needs to be.
And, as Lisa pointed out already, things should not become more
complicated for the average web developer and consultant as it already is.
You, Stefan, will probably get it right if we did this, I would, too, and
presumably everybody else on this list. But the potential for mis-use of
even more roles and stuff is so big that I am really scared. In my
opinion, this has the potential to be misused just as much as role
"application".

Hi Marco,
because (as I have written) from an implementers viewpoint, adding a
“trigger“ or a member in the list of
roles where ARIA labelling has to be supported (which is what they
actually do for some but not all roles) is maybe on a higher acceptance
level.
However,
<span role=”application” aria-label=”Out of stock – That is Critical”
style=”color:red”>Out of Stock</span>
will work already, too, but role=application will be likely deprecated in
ARIA 1.1.
Regarding your last post: Applause for the FF / NVDA support of this but I
do not see any contradiction in emphasizing by role that something is more
than just plain text.

Hi Stefan,
OK, trolling back:
What makes you think they'll support role="text" if they don't get aria
labelling right now?

Hi Marco,
I’m in the mood for some trolling since I don’t understand sometimes
implementation logic behind.
Can you please go ahead and tell FS that they should support aria-label
(or labelledby, describedby) e.g. in
<span aria-label=”Out of stock – That is Critical” style=”color:red”>Out
of Stock</span>
in ALL their modes (important!) according to the ARIA spec WITHOUT having
a role applied on the span or on the body?
If they refuse, having
<span role=”text” aria-label=”Out of stock – That is Critical”
style=”color:red”>Out of Stock</span>
will make things clearer for the screen readers that there is more than
just plain text .. namely ARIA-attributed text.

+1000 to that, Lisa! Given the history of the web, I think it is safe to
assume that everything that is nothing else is text, and that text does
not need its own role. None of the examples I have seen in this thread
convinced me that this is either necessary nor in any way helpful.

My 2 cents
Each new role we introduce will create a learning curve for authors, many
of whom will initially apply it incorrectly, killing the user experience,
until an accessibility consultant tells them how to use it correctly.
(Assuming the consultant is not also using it inappropriately - this is
not to be taken for a given.) I say this based on a lot of personal
experience.
If we do not need a new role we should not create it.
All the best

As Matt alluded, the ARIA 1.0 "presentation" role ("none" is a 1.1 synonym
role of "presentation") does not expose any attribute or role semantics,
so this would not expose the text alternative.

I don't think it'd always be limited to a single character.

The role of the span is ambiguous here. Some platforms don't expose the
span at all, preferring to flatten the selection string, so there is no
element on which to hang the label. (Though that might just be an
implementation detail.)
