DocBook

DocBook is OASIS standard for writing structured documents in XML (or SGML, but I feel this is deprecated). Currently there are two lines: version 4 (4.5) written in DTD and beta version of 5 line, which is general schema clean-up and is written in RELAX NG.

PyArticle now aims to support and converts via version 4.5 as 5 is not stable yet and is not yet supported by most of tools.
