RE: 4.3 Text Alternative Computation Example under 2B

Hi Bryan,

Thanks for the explanation. I think an example with child node under 2 B should
be added to show that acc name changes under certain circumstances.

Hi,

Both examples are correct.



The first one in the spec is correct because the “/>” at the end of the
element indicates that this is an automatically closed element that has no
inner HTML. This is also true for elements that have no child elements by
design such as IMG, Input, etc.



Your example however uses an element that does support child elements and
does have embedded content, so your example changes the accessible name to
reflect the content as the accessible name in accordance with the spec.

Refer to the code snippet under #2B (https://www.w3.org/TR/
accname-aam-1.1/#mapping_additional_nd_te) –

<element1 id="el1" aria-labelledby="el3" />

<element2 id="el2" aria-labelledby="el1" />

<element3 id="el3"> hello </element3>

Where second bullet says, “element2 has no accessible name. The computation
involves a first traversal of its aria-labelledby leading to element1, but
element1's aria-labelledby is not subsequently followed.”

I think element2 does have an accessible name. It is the innerHTML of
element1. Note - IDREF upon subsequent traversal at element2 points to
element 1.

 Here is an example similar to the one under #2B:

 <a id="el1" href="#" aria-labelledby="el3">Link 1</a>

<a id="el2" href="#" aria-labelledby="el1">Link 2</a>

<a id="el3"> hello </element3>

On testing with JAWS 17 / 18 and NVDA 2017, Link2 (with aria-labelledby
pointing to Link1) is read as Link1, which implies Link2’s accessible name
is Link1.

Thanks,
