This reference contains information an experienced Web developer needs to use XML on established and new Web sites. This text is divided up into five major parts. The first teaches the fundamentals of XML language, with emphasis on the creation of XML pages and their publication on the Web. It also discusses rules for creating well-formed XML documents and using UNICODE to create documents in other languages. Part 2 discusses Document Type Definition (DTD) documents. Part 3 covers the various style languages that can be used in conjunction with XML to define the appearance of documents. Part 4 explores a number of supporting technologies, many still in the proposal stage, including XLinks, XPointers and RDF. The CD includes all source code, a complete XML site, all relevant approved W3C specifications and a selection of useful development and display tools.
