The sort spec list is of the form:
    (field flags)+
    where field is either a string or one or more attribute pairs
    key=value (there must be no blanks in either field of flags).
    flags is a character list:
    dD>    : descending
    aA<    : ascending   (default)
    iI     : ignoreccase / case-insensitive (default)
    sS     : respectcase / case-sensitive
    !      : abort of key is omitted in result
    =value : missing value

Examples:
