Conformance Tool is failing for Schematron validation

Schematron validation fails when combining the "ProducerReferenceTime" tag and the "ContentProtection" tag in the same Manifest. However, the validation passes when only one of these tags is present.

Attached Manifest:

Conformance tool result:

Check 5.3.7.3 of the 5th Edition of the DASH spec - ContentProtection and ProducerReferenceTime elements are defined as part of a xs:sequence in RepresentationBaseType. This means that the order is meaningful.

Move ProducerReferenceTime to appear in the expected order (in this case, directly after ContentProtection) in the AdaptationSet and your manifest will validate.

Thank you for the update. Manifest validation now successfully passes.
