X.209 (11/88)
Specification of Basic Encoding Rules for Abstract Syntax Notation One (ASN.1) �
CCITT Recommendation X.209 has been withdrawn on 30 October 2002 as it has been superseded by ITU-T Recommendation X.690. All known defects in X.209 have been corrected in ITU-T Recommendation X.690 (1993) further revised in 1997 and 2002. If you are a protocol designer creating new ASN.1 notation, you should use the 2002 version of ASN.1 encoding rules as defined in ITU-T Recommendations X.690-X.693 (2002) instead of using CCITT Recommendation X.209. For further information, please see "Changing from ASN.1:1988 to ASN.1:2002" on the ITU-T Study Group 17 web page.
