Hello, I’d like to propose you to look into our software. It’s Syntext Serna WYSIWYG XML Editor. We’ve made it free several months ago.
Serna Free provides a lightweight solution for students, open source developers, and other users to work with DITA, DocBook, and other popular XML formats. You may read information about it here: http://syntext.com/products/serna-free/ Also, you might be interested in Serna Enterprise version, which has special support for DITA: http://syntext.com/products/serna/dita-xml-format-support/ It would be great if you decide to add a link to Serna in you list of DITA editors: http://db.apache.org/derby/manuals/dita.html Have you any question, please feel free to contact me. Thank you. Regards, Daria Chernova
