+// This module contains the Subnetwork Dependent Convergence Protocol
+// 44.065 v7.0.0 with attributes for RAW encoding/decoding.
+
+// According to 3GPP 04.64 - the maximum(!) length of the PDU_SN_UNITDATA and PDU_SN_DATA
+// is minimum 140 and maximum 520 octets.
+// The actual length of the PDU_SN_UNITDATA and PDU_SN_DATA is given in LLC ASPs or set to a parameter value.
+// The possible maximum length of dataSegmentSnUnitdataPdu or dataSegmentSnDataPdu is therefore variable and
+// will depend on this setting.
+// The RAW decoder should have no problem decoding these fields when they are simply defined as octetstrings
+// and stand at the end of the SNDPC PDUs.
