rA11y Update:
Got consultation from FARM.
  • Important feedback included the need to reach out to our dev. hours contributors.  Mentioned the prescient of agreeing on hourly rates for development contributions, and that that could be part of how a development donor could work on an issue that represents 110% of donated hours. The need for an estimate of work/need.
 Putting together a plan for further pledges to rA11y.
 Would like to make this asks with the benefit of estimates on the work required - which makes step one getting estimates on the work required.  
Off-screen text
SSB Bart has offered this advice (to be further updated Aug 31st)

Yes, the clip property has been deprecated by the clip-path property. You are correct that it should not be commented out but left in uncommented to support older browsers. From what I understand clip-path is not well supported and thus also required another step to add in some SVG to each page that uses this technique. The technique is discussed here:!/2015/01/updated-offscreen-techniques.html

Regarding WebAIM’s recommendation to just position text off-screen and not use clip or clip-path – we generally don’t recommend that as it causes the screen to jump on mobile device in particular on iOS as the screen reader VoiceOver tries to draw a rectangle off the left edge of the screen.

As you might imagine there is no perfect solution and generally it our recommendation is to not use off-screen text. There may be other ways to provide access to the same information such as putting the text on-screen or on-screen collapsed so it may benefit all users including users with low vision. Other options exist as well to use aria-describedby or aria-labelledby to associate content elsewhere on-screen with a control. As the WebAIM article points out – interactive content should not be off-screen but appear on-screen when focused.

In regards to updating our best practice with this information, it is on the list to be addressed later this week or next. A recent security upgrade caused an issue with editing certain types of examples in AMP and so the update of the best practice was delayed until the issue is addressed.

Best Regards,

Things that need testing for 11.2 - Matt C & J and rest of call tested until screen reader, Matt C to follow up and mark as tested.
General Sakai Accessibility
Someone at UVa asked if it would be possible to have Sakai check PDFs for accessibility when an instructor uploads a PDF and give an alert if it's not marked up correctly for accessibility.  
Any thoughts on this?  Is there, for example, a JavaScript or Java-based library that could look for text showing operators in the PDF file?
Looks like file upload can check here, don't know what they're using:
Here's a java service that was developed for Moodle, don't know what the license is, possibly with some amount of work could be incorporated or at least run locally
