DSD (Document Structure Description) is an XML Schema language co-developed by AT&T Labs - Research, NJ, and BRICS, University of Aarhus, Denmark. The goal of DSD is to provide a schema syntax capable of strong data typing and context-dependent content models.

The DSD site provides free source code, a meta-DSD that can be used to validate DSD schemas, and an XSLT stylesheet that can be used as a default stylesheet for instances of XML documents conforming to a DSD schema for outputting HTML. Substantial documentation and numerous examples are also provided.
