See minutes online for a more detailed record of the discussions.
There were only one topic discussed on the call: Issue 291 on the structure of Table of Content (ToC). The current draft is fairly often as for the exact content of an element designated as a ToC and the issue is whether more should be said. A summary of the issue is also available, which was the starting point of the discussion.
However, no consensus have been identified on the call. One possible compromise solution was put forward on the call, namely the possibility to define two, different approaches: one a more structured version which puts structural requirements on the HTML element identified as a ToC (reminiscent of the similar requirements in EPUB), the other being completely unstructured, under the full control of the author but that the User Agent may not interpret as part of some pop-up ToC, “just” display unchanged.
The discussion is going on; see the issue comments for further details.
There will be no call on the 3rd of September (Labor day in the US).
