They are a bit verbose, but: 1) I'd really like to stick to the specification as closely as possible.
2) There are are several PBCore instantiation properties that apply to the entire file like duration and tracks that we'd want prefixed with pbcore so I think it would be odd to see: pbcore:instantiationDuration=00:00:05.20 stream[0]/pbcore:essenceTrackType=Video 3) PBCore allows for essence track types like text that might not necessarily be considered 'streams'. That's great that the Ogg parsers will be able to do the informational side!
