Overview

To leverage XML's full power, organizations need shared vocabularies based on XML Schema. For a full decade, Definitive XML Schema has been the most practical, accessible, and usable guide to working with the XML Schema specification. Now, author Priscilla Walmsley has thoroughly updated her classic to reflect the new XML Schema 1.1 spec and present today's best practices for constructing successful schema. Walmsley explains the current XML Schema standard with unsurpassed insight and clarity, and introduces practical techniques for writing schemas to support any application, including many new use cases. Walmsley explains how XML Schema 1.1 provides a rigorous, complete standard for modeling XML document structure, content, and datatypes, and guides users through all facets of working with schema, including composition, instance validation, documentation, and namespaces. She covers each XML schema building block, offers an in-depth primer on effective schema design, and presents advanced techniques ranging from type derivation to identity constraints. This edition adds extensive new coverage, including:

Many new design hints, tips, and tricks
Factors to consider when designing schema for narrative content, Web services, and data binding
An entirely new chapter on assertions
Substantially updated coverage of redefining and overriding schema components, naming/design rules, extensibility, reuse, versioning, and more
