    coding one or more syntax elements that indicate a layer identifier of the one or more non-VCL NAL units; and

    determining a set of layers of the multi-layer bitstream to which the non-nested decoded picture hash SEI message is applicable based on the one or more syntax elements that indicate the layer identifier of the one or more non-VCL NAL units containing the non-nested decoded picture hash SEI message.
