ARIA works fine on HTML 4. HTML 5 will have some restrictions. I think the
problem is related to the labelling. Either IE (API Mapping) or JAWS is not
dealing with this properly. Also the checkbox in HTML 4 is in quotes unlike
in html 5. I don't know if that is an issue.

Do they support role/other ARIA attributes which would make the example
work? Of course I want their support for HTML 5, but I've always got an eye
out for workarounds when it comes to installed client software.

      Hi Gregory,

      Thanks for giving it a spin. I think I know the main problem. We are
      using the HTML 5 labelling mechanism:

      <label><input type=checkbox id=showA> Show As</label>
      <label><input type=checkbox id=showB> Show Bs</label>

      versus the standard:

      <input type="checkbox" id="foo" />
      <label for="foo">Show As</label>

      So, either IE does not map the accessibility API properly or JAWS
      simply does not handle this. I will send the example off to Freedom
      Scientific. Freedom Scientific does not yet support HTML 5 in their
      products.

      aloha, rich!

      using IE9 beta and JAWS 12 (latest official release) i can minimally
      access the contents of

      http://lists.w3.org/Archives/Public/public-canvas-api/2010OctDec/att-
      0035/CanvasEditor.html

      1. when i issue a ReadAll command, i hear: "Show As Show Bs";

      2. when i tab navigate to the document via the IE9 chrome, i hear:
      "Show As Show Bs";

      3. when i tab navigate the document itself, i hear: "Show As" -- a
      subsequent tab does not cause JAWS to announce the second item in
      the canvas ("show Bs")

      3A. if i tab navigate the document itself, whilst nothing is
      announced
      when i tab a second time, a DownArrow causes JAWS to speak "Show Bs";

      4. the checkboxes which the document source indicates should be
      included
      in the canvas element are totally invisible to JAWS;

      5. i could not determine if pressing the SPACEBAR while on 1 of the 2

      checkboxes activated the checkbox;

      6. i could not use JAWS' checkbox hot key (x) to access either
      checkbox;

      7. using the "List of Form Controls" command (INSERT+F5) i received a

      list of two items:

      check box not checked
      check box not checked

      but only the existence and state of the checkboxes are reported, not
      their labels ("Show As" and "Show Bs"); when i attempted to select
      one of the checkboxes using this mechanism, a recheck of the "list
      of form controls" indicated that the checkbox remained unchecked

      7A. i could not activate either checkbox using the "List of Form
      Controls"

      let me know if you want/need more testing

      hope this helps, gregory.
