Note: It is semantically correct for multiple KindBoxes to exist in the UserDataBox. Additional box instances may be used to add specificity to a role description or present a semantically equivalent role description for a different scheme. If multiple schemes are present, the schemes should be preferred in the order described above.
Editor's Note: This is not explicitly called out as a case in the CMAF specification, but this is a correct usage of the DASH role scheme in DASH manifests and would appear to be appropriate in CMAF tracks as well.
