Re: ACTION-1349: Creation of aria-placeholder

Right. Neither of IAccessible2 or ATK provide an API to expose it and I
don't recall that anybody had asked for it. Iirc OS X API only has a way to
expose a placeholder. So aria-placeholder should be a nice addition for
VoiceOver, everyone else probably won't benefit from having it.
Thanks.
