Re: [aapi] live roles

Hi Stefan,

When a user agent is mapping aria roles to platform roles, sometimes
there is no good candidate platform role. In these cases we can go with
a best-guess match for a platform role, or we can fall back to a role
based on native markup. Note in these cases we can still expose events
and states to capture the 'live'-ness.

Aside: I feel aria is pushing platform accessibility, so we are in the
churn right now, and probably for the next few years.

cheers,
David
