I don't understand the Literals BNF and I think is maybe an error. The definition says "Any quoted string not containing the quotation Mark", and I think is correct. But production symbols in BNF's Rule contains [^%&"] as final symbols, when an EntityValue is quoted with '"', unless the BNF notation used there is not the common EBNF, there is an error. The same case is happened with the apostrophe symbol. There cases are based on XML 1.0 (third edition), that says: --------------------------- _Literal data is any quoted string not containing the quotation mark used as a delimiter for that string_. Literals are used for specifying the content of internal entities (EntityValue), the values of attributes (AttValue), and external identifiers (SystemLiteral). Note that a SystemLiteral can be parsed without scanning for markup. Literals [9] EntityValue ::= '"' ([^%&"] | PEReference | Reference)* '"' | "'" ([^%&'] | PEReference | Reference)* "'" [10] AttValue ::= '"' ([^<&"] | Reference)* '"' | "'" ([^<&'] | Reference)* "'" ----------------------------------- Aldo Jiménez Aguilar Asistente de Informática de Comercialización Calle Leona Vicario #2 Tula de Allende, Hgo.
