[rules-users] conditional insert of 'exist' or 'not' keywords in decision table s

Hi, I wonder if it's possible to pass some Column keywords as parameters from template values, eg: Condition Condition $1 Driver $1 Policy age >= $2, age <= $3 type exists, 21, 25 , comprehensive not, 64, 100 exists, comprehensive I'd expect the above table would generate two rules like: Rule 1 When exists Driver (age >= 21, age <= 25) Policy(type == "comprehensive") Then // do smth End Rule 2 When not Driver (age >= 64, age <= 100) exists Policy (type == "comprehensive") then // do smth End The above example is just a mock up derived from one of the examples in the documentation to demonstrate the point (meaning, the rules themselves might not make sense from business point of view or can be implemented differently for this particular case). So, any way to achieve this? Whether in current version (3.0.x) or the upcoming release (3.2) Thanks, Vlad
