+    6.4 Target to Source Transparent Container
 
+    The Target to Source Transparent Container contains information that shall be transferred transparently by CN entities
+    from the target RAN to the source RAN.
+
+    When the target network is GERAN, the Transparent container field contains the value part of the Layer 3 Information
+    IE defined in 3GPP TS 48.008 [8], i.e., octets 3 to n, excluding octet 1 (Element ID) and octet 2 (Length).
+
+    When the target network is UTRAN, this container carries the Target RNC to Source RNC Transparent Container IE
+    defined in 3GPP TS 25.413 [9]. The Transparent container field contains a transparent copy of the corresponding
+    ASN.1/PER IE (see subclauses 8.2.2 and 8.48 in 3GPP TS 29.274 [3]).
+
+    When the target network is E-UTRAN, the container carries the Target eNB To Source eNB Transparent Container IE
+    defined in 3GPP TS 36.413 [14]. The Transparent container field contains a transparent copy of the corresponding
+    ASN.1/PER IE (see subclauses 8.2.2 and 8.48 in 3GPP TS 29.274 [3]).
+
+    The receiver of this Information Element shall ignore the length of the transparent container encoded in octet 5 and shall
+    derive the actual length of the container from the length encoded in octets 2 to 3 minus 1.
+
+    For backward compatibility, the sender of this Information Element shall set the octet 5 to the actual length of the
+    transparent container if the size of the container is smaller or equal to 255 octets, and to the value "255" otherwise.
