Paul Cotton, one of the HTML WG Chairs, has arranged for me to work with several members of the HTMLWG on a final draft of the `picture` specification, as we discussed at the HTML WG weekly teleconference on July 26th.
picture is tentatively slated for inclusion under the HTML5 umbrella, rather than being pushed to HTML.next. The status of the proposal can be tracked via the W3C Bugtracker. I’ll be working with Adrian Bateman and Frank Oliver from Microsoft on a formal specification in the coming weeks, and will have an update on our progress by August 16th (per https://www.w3.org/html/wg/tracker/actions/220 ).
Laura Carlson has also been working to gather feedback from the HTML WG Accessibility Task Force on the proposed markup, in addition to being tremendously helpful in navigating the standards process. Welcome to the RICG, Laura!
