The Official Documentation for DocBook.
Intermediate Level Users.
DocBook is a Document Type Definition (DTD) for use with XML (the extensible Markup Language) and SGML (the Standard Generalised Markup Language). DocBook lets authors in technical groups exchange and re-use technical information. The emerging generation of web browsers will be able to read and search XML documents, making it possible for authors to create DocBook documents that function both as professionally produced hard copy books and as online documents available over the World Wide Web. This book contains an introduction to SGML, XML, and the DocBook DTD, and contains complete reference material for DocBook.
