+
+  PURPOSE : Decode basic UNALIGNED PER for extensible SEQUENCE type and
+            SEQUENCE OF. 
+
+            The element can be a field of fixed or variable length.
+            It can contain OPTIONAL elements or integer elements with 
+            a DEFAULT value. The so called nonCriticalExtensions or empty
+            sequences belong to the category of bit strings of fixed length
+            which is set to 0.
+
+            First the extension bit is decoded, then the elements of the 
+            extension root. Finally the elements of the extension addition.
+            See also comments to the encoding function.
