Thank you for the input. I can see the merit of your "uniform Element ID" concept in terms of simplicity for parsers. However, I'm concerned that it would block one of the useful capabilities of the current scheme - the ability to reference chapters from more than one table of contents.

For example, for the recording of a rock festival you could create a CHAP frame for each song and then index these frames in three ways using different CTOCs to provide:
 - a full, temporally ordered table of contents
 - a table providing an index of band names or genres
 - a table listing highlights

I think it's important to maintain this kind of flexibility because it opens up all kinds of interesting opportunities for content developers.

Thanks also for the example content. I'm having problems with this because my chapter tool application is based on the Jens Vonderheide API and this doesn't currently support ID3v2.4. Does anyone have a fix for this?
