1. Latest Versions of DocBook Schemas
Since July, 1998, the DocBook Technical Committee of
OASIS (Organization for the Advancement of Structured
Information Standards) at
has been responsible for the advancement and maintenance of the DocBook
schemas, including any schemas from a subcommittee that are approved by
the DocBook Technical Committee.
The latest releases of DocBook can be obtained from the official
DocBook home page at
http://www.oasis-open.org/docbook/. All normative versions
of the DocBook standard, including derivatives like the Publisher’s
schema, are available at this site.
Information about the most commonly used, non-normative
customizations of the DocBook schema, such as Simplified DocBook and
DocBook Website, can be found at
The only schemas that are considered normative standards are those that have been approved through the OASIS process by the DocBook Technical Committee.

You can subscribe to either list at:
- DocBook stylesheets
The DocBook stylesheets are a set of stylesheets for use with an XSLT engine like xsltproc or Saxon. The stylesheets can transform DocBook XML documents (including documents using DocBook 5.0 and earlier versions) into output formats like HTML, PDF, various help formats, and the ePub ebook format. The stylesheets are open source software maintained by the DocBook community.
- DocBook Wiki
The DocBook Wiki contains a wide variety of DocBook information, from FAQs to lists of consultants.
- Robin Cover’s “Cover Pages”
A large list of XML resources:
Newsgroup devoted to XML issues. This newsgroup can be accessed through Google Groups at:

9. XML Tools
Here is information about some of the tools mentioned in this book. If you are running Linux, you may be able to load some of these tools using a package manager like Synaptic, yum, or apt. Needless to say, this is not a comprehensive list; there are other capable tools available. However, these are a good starting place.
- RELAX NG
A variety of tools that support RELAX NG can be found at:
http://relaxng.org/. These include:
An open source program that is a companion to Jing, Trang converts between various XML schema languages. It supports both compact and XML syntax for RELAX NG, XML 1.0 DTDs, and W3C XML Schemas, though it only supports W3C XML Schemas for output.
- EMACS nXML mode
This is an open source addon for emacs that supports syntax-directed editing using a RELAX NG compact mode schema. It validates as you type and will show you at any point what the valid set of elements, attributes, and attribute values is. It also supports automatic completion of partially typed elements, attributes, and attribute values.
Saxon is an XSLT processor. The basic processor is available as an open source product, and there are also commercial versions that offer additional features. The latest versions of Saxon support both XSLT 1.0 and 2.0.
- <oXygen/> XML Editor
The <oXygen/> XML Editor is a popular commercial editor. The latest versions support DocBook V5.0, including both the RELAX NG and Schematron rules. It is also integrated with the DocBook stylesheets.
- XMLmind XML Editor (XXE)
The XMLmind XML Editor is a popular commercial editor that comes in two varieties, a personal edition and a professional edition. The personal edition is free for non-commercial use. Both versions support DocBook V5.0.
