I have found this document that discusses how to add revisioning into xmlmind: http://osdir.com/ml/editors.xxe.general/2005/msg00395.html
This works well. However, how do I make the 'changed' 'deleted' and 'inserted' flags make it look in the PDF like something like this: http://www.deltaxml.com/free/docbook/ (go to the URL and click "compare" and look at the resulting PDF). I don't care if XMLMind shows the correct versioning, but that would be nice.
