Hmmm... I don’t recall seeing anywhere where it states that @kind="metadata"
was required to be a timed resource - is that specifically stated somewhere?
A quick check of the spec simply defines metadata as "Tracks intended for
use from script. Not displayed by the user agent." I do not see a definition
of "track" as used in this context.

Just curious.
