NVDL Use Cases

Validation of XML document against multiple schemas
- E.g. Schematron + W3C XML Schema or Schematron + RELAX NG
- One schema language is usually not enough for good validation
Validation of compound documents
- NVDL can define how namespaces can be combined in document instances
- NVDL can integrate existing schemas written in different schema language
Association between schema and document
- Using !DOCTYPE or xsi:schemaLocation is not very good practice
- NVDL can describe association between document type (namespace) and its schema(s)
