role=tree on svg

[pkra]

Could the spec allow SVGs to have role=tree? In my experience, browsers and ATs support this combination quite well.

Or, I suppose more generally, @LJWatson's point at #158 (comment) to allow any role on svg (matching SVG-AAM).

Thanks for the issue @pkra. yes, work on 158 may well resolve this issue. Currently planning to discuss this with @stevefaulkner tomorrow or this week.

Thanks, @scottaohara.

takeaway on discussing this today: yes, we need to open up the allowed roles on svg elements, and I see no reason why role=tree would not be one of them.

I personally wonder if things like role=textbox and role=searchbox on the <svg> itself are necessary allowances... noting that any roles are presently allowed on child elements of the <svg> so any possible need for those roles would be allowed within. but I digress. really just wanted to make it known that this will be updated.
