Additionally, to satisfy...
(DV-8) Allow the author to provide fade and pan controls to be accurately
synchronized with the original soundtrack.
(CN-2) The navigation track should provide for hierarchical structures with

Suggested spec text:
When a track is enabled (and depending on the type of track), the playback rate
of a media element may be (temporarily) stopped, slowed down, or sped up to

user to navigate to time offsets in the original content.

Additionally, user agents should ensure that the presentation of the time-based
original content and track content should always be in sync.
