Actually, there are sample XML files included: have a look in the console/data directory...
As you will notice, there are three different weapon configs, I haven't decided on a specific method yet (weapon.xml is the one currently used in the code, I think). One approach is to store all properties of a weapon (like cone angle, damage etc) and code a generic evaluator that translates these attributes into scores for different situations, while the other approach is to store the scores for each weapon directly (and let the user modify it as he wishes). Btw, I don't know if the dtd-specifications are up to date, didn't really make sense to me to work on those without knowing what I'd finally need...
