+            The encoding rule for this type is very similar to the 
+            CSN.1 type. Except for the presence flag which is 0 in 
+            this case. 
+            The encoded IE consists of one bit for presence flag and 
+            a value part. Only if the flag bit is equal 0 the value 
+            part will follow it.
+
+            The element value can be present, then it is preceded by the 
+            flag value 0. If the element is represented by the flag 1 only 
+            the value is absent! Besides the absence of the whole element 
+            is allowed.
