Abstract

   The Generic String Encoding Rules (GSER) describe a human readable
   text encoding for an Abstract Syntax Notation One (ASN.1) value of
   any ASN.1 type.  Specifications making use of GSER may wish to
   provide an equivalent Augmented Backus-Naur Form (ABNF) description
   of the GSER encoding for a particular ASN.1 type as a convenience for
   implementors.  This document supports such specifications by
   providing equivalent ABNF for the GSER encodings for ASN.1 types that
   commonly occur in Lightweight Directory Access Protocol (LDAP)
   syntaxes.
