What’s the difference between the “wairole” and “role” attributes?

Question

I have begun doing dojo accessibility testing on a web application and have noticed that elements have both a role and a wairole attribute that seem to be the same value.

After much searching I have been unable to understand the difference between the two. Can anyone explain this?

Answer 1

wairole attribute is no longer used. Use role as per WAI-ARIA 1.0 and HTML5
