+  PURPOSE : Decode UNALIGNED PER extensible ENUMERATED and INTEGER type 
+            PER-visible constraints restrict the integer value to be a
+            constrained whole number. This gives a lower and an upper 
+            bound for the integer. The lb is also called offset. The 
+            encoded value is the difference between the actual and the
+            offset value.
+            A possible and meant default value is never encoded.
+
+            If the value is in the extension root, it will be encoded as
+            a normally small non-negative whole number. Otherwise it will 
+            be encoded in the smalles number of bits needed to express
+            every enumeration.
