   RE: [xml-dev] Typing and paranoia

[ Lists Home | Date Index | Thread Index ]

It has a DTD because schemas are written using XML 1.0 syntax, so what? The input to a schema for validation and its output are not XML 1.0 documents but XML Infosets. I consider this far more relevant than whether the syntax for authoring schemas uses XML 1.0 syntax, a RELAX NG style compact syntax or EBNF.

	Yes, but Len asked "Why does it a DTD?" So why does it?
