Schematron

• Does not define a “schema”, defines rules to validate instances
• Based on path expressions rather than grammars
• Originally a “meta-application” of XSLT
  • assertions are composed in XPath
    about what is to be expected or warned against
  • a generic stylesheet processes assertions and returns stylesheet
  • resulting stylesheet is run on the instance and
    generates a validation report
• Is currently being abstracted away from XSLT/XPath
• Originated by Rick Jelliffe (Topologi in Australia)
• Now part of DSDL (ISO/IEC 19757)
