940  sabnf += "; Compliant with RFC 7405 for case-sensitive literal string notation\n"
941  sabnf += "; - accepts %s\"string\" as a case-sensitive string\n"
942  sabnf += "; - accepts %i\"string\" as a case-insensitive string\n"
943  sabnf += "; - accepts \"string\" as a case-insensitive string\n"
944  sabnf += "; - accepts 'string' as a case-sensitive string\n"
945  sabnf += ";\n"
946  sabnf += "; Some restrictions:\n"
947  sabnf += "; 1. Rules must begin at first character of each line.\n"
948  sabnf += "; Indentations on first rule and rules thereafter are not allowed.\n"
949  sabnf += "; 2. Relaxed line endings. CRLF, LF or CR are accepted as valid line ending.\n"
950  sabnf += "; 3. Prose values, i.e. <prose value>, are accepted as valid grammar syntax.\n"
951  sabnf += "; However, a working parser cannot be generated from them.\n"
952  sabnf += ";\n"
953  sabnf += "; Super set (SABNF) additions:\n"
954  sabnf += "; 1. Look-ahead (syntactic predicate) operators are accepted as element prefixes.\n"
955  sabnf += "; & is the positive look-ahead operator, succeeds and backtracks if the look-ahead phrase is found\n"
956  sabnf += "; ! is the negative look-ahead operator, succeeds and backtracks if the look-ahead phrase is NOT found\n"
957  sabnf += "; e.g. &%d13 or &rule or !(A / B)\n"
958  sabnf += "; 2. User-defined Terminals (UDT) of the form, u_name and e_name are accepted.\n"

964  sabnf += "; e.g. rule = A / u_myUdt\n"

967  sabnf += "; e_name \n"
968  sabnf += "; 3. Case-sensitive, single-quoted strings are accepted.\n"
969  sabnf += "; e.g. 'abc' would be equivalent to %d97.98.99\n"

975  sabnf += "; 5. Back referencing operators, i.e. \\rulename or \\e_name or \\u_name, are accepted.\n"
976  sabnf += "; A back reference operator acts like a TLS or TBS terminal except that the phrase it attempts\n"
977  sabnf += "; to match is a phrase previously matched by the rule or UDT 'rulename', 'e_name' or 'u_name'.\n"
978  sabnf += "; There are two modes of previous phrase matching - the recursive mode and the universal mode.\n"
979  sabnf += "; In universal mode, \\rulename matches the last match to 'rulename' regardless of where it was found.\n"
980  sabnf += "; In recursive mode, \\rulename matches the last match found on the closest recursive parent.\n"
981  sabnf += "; It would be used primarily with \"nesting pairs\" type recursive rules.\n"
982  sabnf += "; Back reference modifiers can be used to specify case and mode.\n"
983  sabnf += "; \\A defaults to case-insensitive and universal mode, e.g. \\A === \\%i%uA\n"
984  sabnf += "; Modifiers %i and %s determine case-insensitive and case-sensitive mode, respectively.\n"
985  sabnf += "; Modifiers %u and %r determine universal mode and recursive mode, respectively.\n"
