[Charles Goldfarb:] | Questions like this are more easily analyzed if we avoid the confusing | term "optional DTD". A missing DTD is really an implied DTD (like | SGML's implied SGML Declaration) in which all element types have mixed | content consisting of "(#pcdata | any element type)*" and all | attributes are CDATA #REQUIRED (except for special conventions for ID, | etc. that we might adopt). There is no "implied DTD" of this nature in XML. It is possible for a well-formed XML document to be parsed in the absence of a DTD. In such a case, the DTD does not maintain a noumenal existence; it just really isn't there at all. Jon
