Re: Proposal: remove aria-describedat from the ARIA 1.1 specification

You also do the following:

Deborah,

Is it important to show the relationship to the extended description or
could an implied grouping work?

<div role="group" aria-label="Periodic Table">
<img src="foo" aria-describedby="baz" title="periodic table">
<div id="baz">This is a picture of a the periodic table as it would appear
in 1900</div>
<details>
<iframe src="extended description file"/>
<summary>Extended Description</summary>
</details>
</div>

I am sorry about that. We tried to make it very clear in the
requirements documents but obviously did not succeed.

DPub Has no opinions about which solution gets proposed, as long as one
does. We understand that the only way in which aria-describedat would
have solved the problem was by implicit association; it was being
implied that it would be used to mean extended description only, which
is not rational, since that was not part of the definition.

Regular describedby clearly has a use case of being something that
content creators need need for descriptions which automatically show in
the page, because people are using it that way in the wild. Extended
description is definitely something else -- serving the use case also
served, for images only, by longdesc.
