Hi Frank, David

I spoke with Charles and I think we can reproduce the same functionality
with existing ARIA attributes on existing HTML elements in canvas using


We could basically have:

<mark aria-invald="grammar"> See Spot fast run </mark>


<mark aria-invald="spelling"> See Spot fast run </mark>


<mark aria-selected="true"> See Spot fast run </mark>

This eliminates the need for any new HTML 5 tags. It uses existing ARIA
markup. We would simply need to define its API mapping in the HTML 5
accessiblity mapping document.

These can then be wired to the <canvas> UI and we don't need to make use of
any new API calls. Authors would be required to mark the areas accordingly.

Would you support this approach? To me this is low impact comparative to
any other solution we have now.

The only think we don't address is a replacement for the caret found in
contenteditable areas. So, to have a caret we would need to use either a
textfield or a contenteditable area - unless we add a feature.
