The authoritative XML Schema reference and tutorial!
- Leverage the full power of XML Schema!
- In-depth coverage of the approved W3C Recommendation
- Schema design—practical and thorough
- Transition help for experienced DTD developers
- Authoritative! By Priscilla Walmsley—a member of the W3C XML Schema
Working Group
To leverage the full power of XML, companies need shared vocabularies to base
their documents and scripts upon. XML Schema makes it possible to create those
shared vocabularies-and Definitive XML Schema is the authoritative guide to
the standard! Written by Priscilla Walmsley, a member of the W3C working group
that created XML Schema, this book explains the W3C Recommendation with unprecedented
insight and clarity—and introduces practical techniques for writing schemas
to support any B2B, Web service, or content processing application. Coverage
includes:
- How XML Schema provides a rigorous, complete standard for modeling XML document
structure, content, and datatypes
- Working with schemas: Schema composition, instance validation, documentation,
namespaces, and more
- XML Schema building blocks: elements, attributes, and types
- Advanced techniques: type derivation, model groups, substitution groups,
identity constraints, redefinition, and much more
- An in-depth primer on effective schema design, including naming, document
structure, and extensibility considerations
- Transition guidance for experienced DTD developers
Definitive XML Schema brings together expert guidance for schema design, superior
approaches to schema development, and the most systematic XML Schema reference
on the market. Whether you're a developer, architect, or content specialist,
it's the only XML Schema resource you need!

Customer Reviews: 1 Average Customer Rating: Feb 26, 2003 A review from Raleigh, N.C.
Clear explanation of a difficult specification.
This book has always been within arm's length ever since I received it a few months ago. This author has really helped me get my head around this subject. The writing is very clear, accurate and informative without being pretentious, dry and overly technical. The subject is covered throughly but without fluff.
Many things about XML Schema that I tried to understand before really became clear in this book, and many things were revealed that I was unaware of. The writing style has made the past few months an exciting journey in my work as I discover more and more effective and powerful ways to use schema definitions. I've read it cover to cover and at least half the chapters two or three more times, and I still pick it up to refer to something probably at least once a day.
