Datatype- and Namespace-Aware DTDs: A Minimal Extension

DTDs and XML Schema are important validation languages for XML documents. They lie at opposite ends of a spectrum of validation languages in terms of expressive power and readability. Differently from other proposals for validation languages, DTD++ provides a DTD-like syntax to XML Schema constructs, thereby enriching the ease of use and reading of DTDs with the expressive power of XML Schema. An implementation as a pre-processor of a Schema-validating XML parser aids in ensuring wide support for the language.
