Hi Nigel,
I know the 1.0.1 comment period has closed but can we discuss this briefly tomorrow?
https://github.com/w3c/imsc/issues/329
It affects 1.1 and is more of philosophical question on the noted provisions. After we decide what’s “right” we can decide which versions to apply it to.
Thanks,
Mike
