I agree - which is why I suggested to just use that work as an
inspiration and not take it at face value. That WG has done extensive
analysis of media metadata that is exposed by different media formats,
which is useful to come up with a solution that works for UAs. Their
solution was not directly meant to be used in UAs, I believe.
