Wrox Press has published a full-length volume on XML Schemas in its 'Programmer to Programmer' Series. Professional XML Schemas has been authored by Kurt Cagle, Jon Duckett, Oliver Griffin, Stephen Mohr, Francis Norton, Nikola Ozu, Ian Stokes-Rees, Jeni Tennison, and Kevin Williams. Professional XML Schemas "exhaustively details the W3C XML Schema language, and teaches the new syntax in an intuitive and logical way. [It documents] how to declare elements and attributes, how to create complex content models, how to work with multiple namespaces, and how to use XML Schemas in real-world situations. A number of practical case studies illustrate the design and creation of schemas in the diverse worlds of relational databases, document management, and e-commerce applications." The book covers all major aspects of schema application, including: "(1) A complete guide to XML Schema Syntax; (2) Using XML Schema built-in types, and deriving new types; (3) Working with XML Schemas and XML Namespaces; (4) Creating identity and uniqueness constraints; (5) Good schema design, illustrated in a number of different areas; (6) Working with schemas and XSLT; (7) Writing XML Schemas for working with SOAP; (8) Integrating Schematron and XML Schemas." Reference tools in appendices include Schema Element and Attribute Reference, Schema Datatypes Reference, UML Reference, Tools and Parsers, and Bibliography and Further Reading.

Book overview: "In order to leverage XML's power as a self-describing and extensible language, we need a way to define and describe the allowable content of any type of XML document. In the past, this has been achieved with DTDs, but these have in many ways fallen short in the requirements for working with data. XML Schemas were created to provide a more powerful and flexible mechanism for describing permissible document structures using XML syntax. They provide a set of built-in datatypes, which can mimic the object-oriented mechanisms of many languages, offer support for namespaces, and facilities for automated documentation. The book is designed for any experienced XML developer who needs to get to grips with XML Schemas. Knowledge of other programming languages is not required, but an understanding of DTDs will come in handy."
