XML Schema Quality Checker
XML Schema Quality Checker is a program which takes as input an XML Schema written in the W3C XML schema language and diagnoses improper uses of the schema language. Where the appropriate action to correct the schema is not obvious, the diagnostic message may include a suggestion about how to make the fix. For Schemas which are composed of numerous schema documents connected via <include> <import> or <redefine> element information items, a full schema-wide checking is performed. The tool can also be run in batch mode to quality check multiple XML schemas in a single run.
