Packet classifiers assigned to the Low Latency service flow. Each classifier is encoded in hexBinary according to the TLV encoding. When multiple classifiers exist for the same Latency service flow, then they are encoded as the concatenated sequence of encodings for each classifier. See [MULPIv3.1] Quality-of-Service-Related Encodings (in Annex C). Because the TLV encoding for upstream classifiers is different than for downstream classifiers, the default value for this attribute depends on the value of the Direction attribute.
