While nested chapters are not overly common, we can easily support the use case simply by considering cues which are contained (time range-wise, not syntactically) within another to create a child chapter, as such:

The hierarchy here is:

1. Title Slide
2. Introduction by Naomi Black
3. Talk on WebVTT
3.1. Impact of Captions on the Web
3.2. Requirements of a Video text format
3.3. Simple WebVTT file
3.4. Styled WebVTT file
3.5. Internationalized WebVTT file

What&apos;s needed in the spec is to specify a simple algorithm for constructing the tree and say that they may expose in UI and to AT this tree. One algorithm was suggested in &lt;http://lists.w3.org/Archives/Public/public-html/2011Jul/0119.html&gt;, but anything will do.</thetext>
