XML Schema Quality Checker is a tool that analyzes an XML Schema and reports any improper usage of XML Schema Language. The program will perform a schema-wide check when multiple schema documents are connected, and has a batch mode available for automating larger jobs.

XML Schema Quality Checker is now compatible with the new XML Schema Recommendation.
