Agenda+ DAPT

Latest WD (currently 2025-04-12) published at https://www.w3.org/TR/DAPT/

For information only: Requests for Wide Review and Horizontal Review

DAPT WR outgoing liaisons complete.

HR requests sent to APA WG, PING, Security, TAG and Internationalisation.

Awaiting responses, from all except PING, Internationalisation and TAG who completed their reviews.

APA WG is likely to approve, and are consulting their members about asking for a change in emphasis of the non-normative text about audio description mixing to promote client-side mixing since it allows more user choice. Potentially we could make such a change anyway.
