Tomas Kukosa c388131e82 - RNSAP regenerated from the last specification Release 6 V6.13.0 (2007-03) 
(original unchanged ASN.1 source could be used because asn2wrs has been improved)
- IE value switch(){} replaced with dissector table
  (some switch() and dummy CHOICE still remains but will be removed soon)
