[rules-users] FW: About Drools

Fri Sep 28 04:12:45 EDT 2007

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.
