Why is the following condition added to paragraph 3.1 of the XML spec? === Well-Formedness Constraint: No External Entity References Attribute values cannot contain direct or indirect entity references to external entities. === This is extremely interesting. How is a processor going to know if an entity refers to something external unless it reads the (external) DTD? If it has to read the DTD, how can this be a well-formedness constraint? I mean, isn't it a validity constraint? If it's a validity constraint, then it makes no sense to me (entities can resolve perfectly well both inside and outside of attribute vals). (I'm sorry if this is a dumb question.) Richard Goerwitz
