Docbook is the most popular DTD for technical documentation. Serna package includes a Docbook XSL stylesheet, which renders documents as closely to Norman Walsh's Docbook stylesheet as possible.
Serna Docbook stylesheet is based on the Norman Walsh's stylesheet and modified in order to provide convenient WYSIWYG editing and optimal performance for dynamic execution.

Norman Walsh's Docbook stylesheet is located at: /usr/share/xml/docbook/stylesheet/docbook-xsl. Serna Docbook stylesheet is located at: sernaInstallationPath/plugins/docbook/docbook-xsl-serna.
Serna Docbook stylesheet may be parameterized very similarly to Norman Walsh's Stylesheet (see files at sernaInstallationPath/plugins/docbook/docbook-xsl-serna: parameters.xsl and titlepage.templates.xsl that is generated with titlepage.generator.xsl from titlepage.templates.xml).
