The widely-adopted XML schema for marking up books of all kinds is now presented for public review prior to its submission to the members of OASIS as a candidate for OASIS Standard.
OASIS and the DocBook TC  are pleased to announce that The DocBook Schema Version 5.2 is now available for public review and comment.
DocBook is a schema (available in languages including RELAX NG, SGML and XML DTDs, and W3C XML Schema) that is particularly well suited to books and papers about computer hardware and software.
Because it is a large and robust schema, and because its main structures correspond to the general notion of what constitutes a “book,” DocBook has been adopted by a large and growing community of authors writing books of all kinds. DocBook is supported “out of the box” by a number of commercial tools, and there is rapidly expanding support for it in a number of free software environments. These features have combined to make DocBook a generally easy to understand, widely useful, and very popular schema. Dozens of organizations are using DocBook for millions of pages of documentation, in various print and online formats, worldwide.
The TC received four Statements of Use from from Norm Tovey-Walsh, XML Press, the SUSE documentation team, and Jira Kosek. .
