The wikibook DTD is a modified version of the tbook DTD that Torsten Bronger developed. The modifications extend tbook to support the Text Formatting Rules and Wiki Styles, thus enabling Wikipublisher to compose any wiki page or page collection into PDF. Wikibook is a superset of tbook — an XML document that validates against tbook version 1.5 should also validate against wikibook.
The Server transforms wikibook XML to LATEX. The wiki transforms wiki markup to XHTML, so we have not provided a modified version of the tbook to XHTML xslt script. As of Wikibook PDF server version 1.1.11, we also provide an option for wikibook to DocBook transformation.
The current DTD version is 1.2a.
