What do you think of just iterating over all HTML attributes and exposing
everything with an aria- prefix? That would match what Firefox does.

I guess we'd have to exclude a few like aria-live that we're already handling,
above.

[je_julie(Not used), 2015/06/10 02:16:31]

When I looking into the inspection result from Accessibility Viewer,
Firefox has some html attributes depending on html tag for IAccessible2->Object
Attributes and all aria-attributes for ARIA->Attributes.('->' means inspection
menu depth.)
Chrome also has some html attributes for IAccessible2->Object Attributes and all
aria-attributes for ARIA->Attributes.

Because this part is for handling of IAccessible2->Object Attributes, I think we
don't need to expose all aria-attributes here.
I think it's enough to handle some html attribute according to spec. WDYT?
