XML Schemas: W3C Recommendation (very soon!)
Issues with XML 1.0 DTDs
- Special DTD syntax
- XML namespaces break DTD validation
- DTDs provide uselessly weak datatype validation
- DTDs provide weak composition and extension framework
Requirements
- Use XML syntax to leverage common toolsets and training
- Support real validation of namespaced documents
- Provide rich inventory of datatypes
- Bring structured design principles to XML schema design
