Thanks. My problem with this is that these constants would have to be
defined in my Java application and then inserted into the session, I
think. What I would aim for is to have ALL the business logic in the
DRL file, but setting constants such as lowTargetLimit = 80 in the
application and then pushing that into the session object does not
make sense to me.
As I write the DRL file with more confidence, I suppose I will end up
creating a DSL. I was just hoping there might be a simple way to
