I suggest the following addition to the "Video UC's" section of [1]

  Variantions of a video fragment

Some video streams (e.g. DVD titles) may be viewed in different versions
based on user's preferences: different soundtracks, different subtitles
(if any), sometimes different angles (e.g. live music DVDs). When
specifying a fragment of those streams, it should be possible to specify
which variation is considered. However, it should also be possible for a
fragment to be under-specified with regards to variations: sometimes,
one would like to address the fragment with a specific soundtrack and
angle (e.g. "the lips do not move accordingly with the voice"), but
sometimes a fragment does not depend on a particular variation (e.g.
"the kiss scene").

(it should be noted that this kind of consideration is somewhat present
in the "Audio UC's" section... however, I think the problem is even more
 complicated with video)
