2.  Standard Attribute Syntax Encodings

   For the purposes of defining the encoding rules for the standard
   attribute syntaxes, the following auxiliary BNF definitions will be
   used:

      ::= 'a' | 'b' | 'c' | 'd' | 'e' | 'f' | 'g' | 'h' | 'i' |
             'j' | 'k' | 'l' | 'm' | 'n' | 'o' | 'p' | 'q' | 'r' |
             's' | 't' | 'u' | 'v' | 'w' | 'x' | 'y' | 'z' | 'A' |
             'B' | 'C' | 'D' | 'E' | 'F' | 'G' | 'H' | 'I' | 'J' |
             'K' | 'L' | 'M' | 'N' | 'O' | 'P' | 'Q' | 'R' | 'S' |
             'T' | 'U' | 'V' | 'W' | 'X' | 'Y' | 'Z'

      ::= '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9'

      ::=  | 'a' | 'b' | 'c' | 'd' | 'e' | 'f' |
                      'A' | 'B' | 'C' | 'D' | 'E' | 'F'

      ::=  |  | '-'

     

::= | | ''' | '(' | ')' | '+' | ',' | '-' | '.' | '/' | ':' | '?' | ' ' ::= The ASCII newline character with hexadecimal value 0x0A ::= | ::= | ::= | ::= | ::=

|

::= ' ' | ' ' 2.1. Undefined Values of type Undefined are encoded as if they were values of type Octet String, with the string value being the BER-encoded version of the value. 2.2. Case Ignore String A string of type caseIgnoreStringSyntax is encoded as the string value itself. Howes, Kille, Yeong & Robbins
