Everything about XML Schema

In order for companies to take full advantage of the XML language, they need common dictionaries on the basis of which they will be able to develop their documents and scripts. The XML Schema language allows creating such dictionaries, and the book All about XML Schema is a reliable guide to this standard.
Priscilla Walmsley, author of the book and member of the W3C working group who created XML Schema, describes this language in a professional and understandable way. It presents practical techniques for creating schemes supporting B2B applications, network services and content processing. It discusses, among others:
-XML Schema as a standard for rigorous and accurate modeling of the structure, content and types of data XML documents;
- working with the scheme: schema construction, document validation, schema documentation, namespaces and other;
- Schema XML components: elements, attributes and types;
- advanced techniques: derivation of types, groups, replacement groups, control of identity, redefinition;
- topics for experienced creators of DTD definitions, and for translating these definitions into the XML Schema language.
Provides detailed guidelines on how to design schematics effectively. It addresses problems related to naming, document structure and schematic expansion.
This book is a great source of knowledge about XML Schema. We hope that it will be useful to programmers and designers.
