One way is for the scripting to add some offscreen text content to the end of the working group text, eiither "Show more information" or "Hide more information"

Modified code:

            <H3 class="h4">
               <SPAN class="expand_section" title="Device APIs and Policy Working Group"><A href="#">Device APIs and Policy <span class="offscreen">Show more information</span></A></SPAN>

>Dear WAI IG,

>One suggestion was to use WAI-ARIA's aria-expanded. However, this will
