RE: aria-level interpretation problem

Thanks Madeleine,

 

Sounds plausible. I didn’t look up further instances of the issue.

 

Is W3C reading these list postings? Looks like they are addressed.

It looks to me like there is an error in the algorithm generating the document. If you look at the Note callouts, they all have a heading level one higher than the containing section; if you look at the Caution callouts, they all concatenate the containing level with the digit one. I suspect they were intended to add the two digits together rather than concatenate them.

HI W3C and community,

 

Is a misinterpretation of aria-level > 6 an issue for WCAG (SC 1.3.1,  4.1.2) or a screen reader bug?

 

For a while I already wondered as a SR-user, why W3C documents flag some notes as H2.

Now I inspected such a component at:

https://www.w3.org/TR/epub-33/#sec-intro-relations

 

In the source was no role=note but an aria-heading with an extraordinary value for aria-level:

 

<div class="caution" id="caution-0">

<div

  role="heading"

  aria-level="31"

  class="caution-title marker">

<span>Caution</span>

</div>

 

For this component , JAWS as well as NVDA announces “heading 2” in Chrome, Edge and Firefox, each for desktop .

 

Possible problems using higher levels are well known: 

“On elements with role  <https://w3c.github.io/aria/#heading> heading, values for  <https://w3c.github.io/aria/#aria-level> aria-level above 6 can create difficulties for users.”

(https://w3c.github.io/aria/#aria-level)

 

So, who has to be addressed for rectification?

 

My preferred mode to get an overview and navigate documents bases on heading hierarchy. And I know, I am not the only one.

 

Thanks,

 

Wolfgang
