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

Ah right, remember a discussion about this. The media query could look at either a setting in de reader or at OS level. Thanks for your explanation!

What they would like to do is have a media query that says expose extended descriptions which would be used to show or hide the details buttons. The user would then need to click on the button (represented by <summary>) to expose the description. So, by default these detail buttons would be hidden. I don't know what they would like to call the media query property.

It also could be an operating system feature that could be exposed by the browser as a media query. All these epub readers are browser based.

This addresses the gaps in browser support. A media query will need to be created at some point to handle the showing/hiding of this element, and I see those discussions are happening, but I believe this addresses the requirements of the digital publishing industry.
