oXygen is an XML editor that supports any XML document, and works with XML Schemas, DTDs, Relax NG schemas, and NRL Schemas. It has powerful transformation support that allows you to edit XSLT and XSL-FO documents and to obtain documents in the desired output format (such as HTML, PS, or PDF) with just one click. It also includes a complete Subversion client, support for flattening XML Schemata, an XML Schema instance generator, integration with the X-Hive/DB, MarkLogic and TigerLogic XML databases, editing actions on the diagram, and a rename refactoring action.
Docbook2odf consists of DocBook XSLT stylesheets and utilities for converting DocBook into OpenDocument. It is not restricted to text-like documents and can generate presentations, charts, or forms with images and multimedia. The result is returned in a zipped ODF file (.odt/.odp/.ods) with all required content.
