Experimenting a Word to Dita to Pdf transformation with open-tools

Less than a year ago, I was made to work with DITA to try to convert Word files to Dita, and that for free, if possible... I then learned to know DITA for Publishers (http://dita4publishers.sourceforge.net/) which was the base of my experiments concerning the Word-> Dita transformation and the DITA Open Toolkit (http://dita-ot.sourceforge.net/) for the Dita-> Pdf side of the work.
I intend to publish here the modifications I made that helped me get closer to the result I wanted :-)!
