XDRtoXSD is a Java-based schema conversion utility for generating W3C XML Schema Language (XSD) schemas based on their XML-Data Reduced (XDR) schema equivalents. Other features include a batch processing mode and detailed error checking, including the ability to recognize when XDR schemas aren't able to express the semantics of the XSD schemas (in which case, the closest possible schema is produced along with an explanation).
