RELAX NG is a grammar-based schema language. This introduction to the language provides XML developers with a no-nonsense method for creating XML schemas. It offers a clear-cut explanation of RELAX NG that should enable developers to focus on XML document structures and content rather than battle the intricacies of yet another convoluted standard.
