Elements defined

instantiationDataRate

instantiationDataRate expresses the amount of data in a digital media file that is encoded, delivered or distributed, for every second of time.

Best Practice: This should be expressed as numerical data, with the units of measure declared in the unitsOfMeasure attribute. For example, if the audio file is 56 kilobits/second, then 56 should be the value of instantiationDataRate and the attribute unitsOfMeasure should be kilobits/second.

Usage: optional, not repeatable
