Re: ISSUE-163 navigating-tracks: Chairs Solicit Change Proposals

Hi Paul, all,

after analyzing this problem thoroughly, which I have documented [1],
I have come to the conclusion that there is no need for introduction
of any normative text into the specification to satisfy this use case.

Right now, we have a linear navigation means through text tracks of
kind chapter.

IMO the best means to provide hierarchical navigation, which is
particularly useful to vision-impaired users, is to make it possible
to provide navigation lists inside the cues that make up
kind="chapters" track. As such cues are handed to AT, their markup is
interpreted and made available to AT, including any associated lists.

My only suggestion would be to potentially add a recommendation to the
specification underneath where "chapters" are introduced [2]
which essentially states that subnaviation within chapter cues should
be provided through list elements (ul,li) inside a chapter's cue.

I'm also curious what others think about to analysis document I've
done and its conclusions.

Best Regards,
Silvia.
