OCTET

Syntax

The EBNF for the textual representation of values of type octet is

Values and Value Lists

octetValue :
    octetNotation;

octetValueList :
    octetValue ( listSeparator octetValue )* ;

listSeparator :
    defaultListSeparator | userDefinedListSeparator | newline ;

defaultListSeparator :
    ',' whitespace ;

userDefinedListSeparator :
    character whitespace? ;

Arrays and Array Lists

octetArray :
     openingArrayDelimiter octetValueList closingArrayDelimiter ;

octetArrayList :
    octetArray ( listSeparator octetArray )* ;

openingArrayDelimiter :
    ( defaultOpeningArrayDelimiter | userDefinedOpeningArrayDelimiter ) whitespace ;

closingArrayDelimiter :
    whitespace ( defaultClosingArrayDelimiter | userDefinedOpeningArrayDelimiter ) ;

defaultOpeningArrayDelimiter :
    '{' ;

defaultClosingArrayDelimiter :
    '}' ;

userDefinedOpeningArrayDelimiter :
    '(' | '[' ;

userDefinedClosingArrayDelimiter :
    ')' | ']' ;

Octet Notation

octetNotation :
    unpaddedOctetValue | leftPaddedOctetValue | rightPaddedOctetValue ;

leftPaddedOctetValue :
    whitespace+ unpaddedOctetValue ;

rightPaddedOctetValue :
    unpaddedOctetValue whitespace+ ;

whitespace :
    ' ' ;

unpaddedOctetValue :
    simpleFormat | otherFormats ;

simpleFormat :
    base16DigitUppercase base16DigitUppercase ;

otherFormats :
    base16CLiteralFmt | base16M2LiteralFmt | binaryM2LiteralFmt ;

base16CLiteralFmt :
    '0' 'x' base16DigitLowercase base16DigitLowercase ;

base16M2LiteralFmt :
    '0' base16DigitUppercase base16DigitUppercase 'H' ;

binaryM2LiteralFmt :
    binaryDigitGroup binaryDigitGroup "B" ;

binaryDigit  :
    '0' | '1' ;

binaryDigitGroup :
    binaryDigit binaryDigit binaryDigit binaryDigit ;

base16DigitLowercase :
    '0' .. '9' | 'a' .. 'f' ;

base16DigitUppercase :
    '0' .. '9' | 'A' .. 'F' ;

newline :
    <runtime host dependent ASCII control sequence for new line> ;

Static Semantics

• all values in a list are shown in the same notation.
• all values in a list are shown with identical formatting.
