 | Useful simpleTypes for W3C XML Schemas
16:14, 22 Jul 2001 UTC | Leigh Dodds Roger Costello has produced two useful simple type definitions for XML Schema authors. These define all known currencies, and ISBN identifiers. Costello has provided the simpleType definition, a sample schema referencing this definition, and an example document for both types. In the notes for the ISBN type, which was co-authored with Roger Sperberg, Costello comments that XML Schema is unable to validate the ISBN check digit. An additional XSLT transform is provided to perform the required modulo-11 check. A Schematron version might be similarly derived. As the ability to define reusable type definitions is core to XML Schemas, the potential exists for collecting an openly available type library. Related Stories: |
