Although you may question the value of even recording that date, we've learned that many catalogers believe this data is worth capturing.

There seems to be overlap with essenceTrackPlaybackSpeed.

Martina McGinn added this on the PBCore Talk listserv: "I agree and suggest that instantiationAlternativeModes could also warrant multiple occurrences (e.g. a film dubbed in English and sub- titled in Spanish). And it seems logical that if instantiationLanguage allows multiple occurrences then so should essenceTrackLanguage." Seems like a minor schema tweak would iron out these rough spots. But of course there are others, and we need to follow through on identifying them, like this one. Jack I second Dave’s motion.
