RELAX NG is a new schema language for XML. This paper discusses various aspects of the design of RELAX NG including the treatment of attributes, datatyping, mixed content, unordered content namespaces, cross-references and modularity.

XML mark-up is used in a wide range of applications and in particular for data transfer via the Internet.

technique based on the document type, expressed as a Relax NG schema. Assuming the sender and receiver agree in advance on the document type, conforming documents can be transmitted extremely compactly. On several data sets with high tag density this technique compresses better than other known XML

Patterns of RELAX NG can represent interdependencies between attributes and elements. Such patterns are useful for schema authors. However, they make validator implementation algorithmically challenging, since naive approaches easily blow up even for typical inputs. James Clark has provided a

We present an approach to controlled document authoring that significantly extends the functionality of existing methods by allowing bottom-up and top-down specifications to be freely mixed. A finite-state automaton is used to represent the partial, evolving, description of the document during authoring. Using a generalization of chart-parsing techniques to FSAs rather than fixed input strings, we show how the authoring system is able to automatically detect the consequences of the choices already made by the author so as to only propose for the next authoring steps choices which may provably lead to a globally valid document. We start by considering the case of authoring purely textual documents controlled by a context-free grammar, then show a generalization of this approach to structured documents controlled by a specification whose formal expressive power is at least that

Abstract. The knowledge representation language RuleML Version 1.0 has recently been re-engineered using the Relax NG schema language, introducing several new features, including on-the-fly schemas with finegrained, freely-combinable modules. The web application Modular sYNtax confiGurator (MYNG
