Further Opportunities 1) Extensions (optional) XML Schemas Custom Data Model XML Schemas feeds into generates Custom Data Model MXV Transformation Methodology XML Component Library Extension Organisation A Extension Organisation C Shared Data of Organisation A, B and C Extension Organisation A Extension Organisation C In-house Schema of Organisation A Extensible 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 From Data Model to XML Schema

Further Opportunities: 2) Value Validation (optional 2-pass) Diagram courtesy of From Data Model to XML Schema
