The XML Schema Quality Checker is a tool that performs diagnostic test including correction of wrong Schema language from an XML Schema input. The Schema input script is in W3C XML schema language. When presentation is vague and determination of favorable solution is not conclusive, the XML Schema Quality Checker generates possible solutions appropriate for the script correction.
