Re: Possibility of moving Personalization Semantics out of ARIA and into APA

I'd also just like to add that moving Personalisation from under the ARIA
WG to under the APA WG will have zero practical impact on the work being
done by the Task Force. It is in many ways organizational, and in the
process opens the TF to potential techniques and technologies not directly
impacted by, or required to conform to ARIA notation or methodologies (not
all AT requires ARIA to function properly). I see that as a positive
outcome of the move.

Additionally, as Joanie notes, if we need "something" from the ARIA WG,
they are committed to addressing that need in the future. This matches the
current commitment today, so we lose nothing in the move.
