that it is intended to extend WCAG 2.0 in needed areas such as low

The "post-wcag2" wiki page was subsequently transformed into the "Post
WCAG 2 Issues Sorted" wiki page. Check the "category" and "What should
WCAG do?" columns for Low vision, Cognitive, Mobile in the first

Z?

I think we may be having concrete examples fairly soon with the Mobile
Task Force's work.
