As to anyone else trying to figure out the XML stuff, I recommend you
write something in DRL first and then use the XMLDumper to see what the
XML looks like. From there if you think something isn't documented, that
should be, please open a jira with the appropriate documentation segment
and we will add it to the manual.

I am also a part of the user-list.
I am using Drools 4.0 with XML rule language.
I want to use the same .xml file with the two java programs.
Here are my programs
