As developers create new XML vocabularies, they often need to describe those vocabularies to share, define, and apply them. This book will guide you through W3C XML Schema, a set of Recommendations from the World Wide Web Consortium (W3C). These specifications define a language that you can use to express formal descriptions of XML documents using a generally object-oriented approach. Schemas can be used for documentation, validation, or processing automation. W3C XML Schema is a key component of Web Services specifications such as SOAP and WSDL, and is widely used to describe XML vocabularies precisely.
With this power comes complexity. The Recommendations are long, complex, and generally difficult to read. The Primer helps, of course, but there are many details and style approaches to consider in building schemas. This book attempts to provide an objective, and sometimes critical, view of the tools W3C XML Schema provides, helping you to discover the possibilities of schemas while avoiding potential minefields.
