RE: aria-labelledby pointing to an element with aria-hidden=”true”

Final comment (I promise):

http://w3c.github.io/aria/core-aam/core-aam.html#exclude_elements2


A respective

>>> Note
>>> Text equivalents for hidden referenced objects may still be used in the name and description >>> calculation even when not included in the accessibility tree.

Is added in chapter below

http://w3c.github.io/aria/core-aam/core-aam.html#include_elements


which I was looking for as “allowing” specification. So all fine for me.

Hi Steve,

On reading

http://w3c.github.io/aria/accname-aam/accname-aam.html#dfn-hidden


I had the impression that aria-hidden falls NOT in this realm since you can also flag visible text with aria-hidden=true violating the ALL users precondition for that definition.

So are we back at square one with my question? Or should the definition changed for it covers also aria-hidden?

Regards
Stefan

Thanks! This was exactly I was looking for. It’s not in the ARIA spec but the mapping guide…
>> that and include *hidden text* as ..

A even sharper one would be clarifying additionally by which means hidden text was hidden (there quite a few, aria-hidden is just one of them).

If this reads

>> that and include *text hidden with any known method (aria-hidden, CSS, display=none etc* as ..

we are fine.

refer to Accessible Name and Description: Computation and API Mappings 1.1

Comment:
By default, assistive technologies<http://w3c.github.io/aria/accname-aam/accname-aam.html#dfn-assistive-technologies> do not relay hidden information, but an author can explicitly override that and include hidden text as part of the accessible name<http://w3c.github.io/aria/accname-aam/accname-aam.html#dfn-accessible-name> or accessible description<http://w3c.github.io/aria/accname-aam/accname-aam.html#dfn-accessible-description> by using aria-labelledby or aria-describedby.

I have a question to the group regarding aria-labelledby pointing to an element with aria-hidden=”true”.

Is that an allowed relation according to http://www.w3.org/TR/wai-aria/ ?

Also, http://www.w3.org/TR/wai-aria-1.1/#aria-hidden and http://www.w3.org/TR/wai-aria-1.1/#aria-labelledby give no clue about this so it seems to be OK.
I do not speak of better alternatives for respective use cases, just if the specification explicitely leaves that as a possible option.
Screen readers (Jaws) currently read information in nodes with aria-hidden=”true” associated with aria-labelledby when respective elements with that relation are focused.
