Re: [Accessibility-ia2] Reverse relationships

[Richard Schwerdtfeger]

Hi Alex,

 

Correct, aria-details requires no special role. However, the use case is for the digital publishing industry. They want to be able to take a piece of content and go to the alternative content that provides detailed information which could be alternative content as we discussed previously. The user may or may not wish to go back to the content the details is being provided for.

 

The need for a reverse relationship for the error message is more critical.

 

So, do we agree on a reverse relationship for error message and not details?

You're right. An element referred by aria-errormessage can be an alert of live region and thus should be announced by a screen reader, when it pops up. In this case, it seems the screen reader may need to find a context element, and if this is true, then the reverse relation is needed.
 

aria-details are different, since they are more like labels and descriptions, and I guess thus they should be skipped when navigating the virtual buffer. That suggests that aria-details either needs a role (or xml-roles object attribute) or a reverse relation.

Hi,

Is that documented somewhere?

I read through the information on error and I don’t see anything about AT skipping error messages if encountering them while reading through the virtual buffer.

Have I misunderstood something?

Thanks,

Brett

Hi, Brett.

Can you please elaborate your use case? My understanding is AT skips error/details, if the user encounters them, but announce them, when the user navigates to an element related with error/details. Why would AT need to find a related element by error/details?

Thanks.

Alex.

Hi Rich,

I think we do need the reverse relationships.

Web authors can place the error/details anywhere on the page and there doesn’t seem to be any simple way for the user to determine what element the error message or details applies to without such a reverse relation.

We need agreement:

 

Should the error message and details relationships have reverse mappings?
