From Data Model to XML Schema Further Opportunities: 2) Value Validation (optional) A standard methodology for validating values in an XML instance • Using OASIS Genericode format for defining code value lists • Using OASIS Context Value Association format for associating XML schemas to code value lists • Using ISO Schematron format for defining more complex business constraints • Generates one run-time Stylesheet for platform-independent validation
