I really like how you can specify a DSL like this (for example): [condition]There is a person=$p : Person() [condition]- with {color} hair=hairColor matches {color} [condition]- with {color} eyes=eyeColor matches {color} [condition]- that is {height} inches tall =height == {height} [condition]- that is {age} years old=yearsOld == {age} If I'm reading the documentation correctly, the rules can then be specified with any subset of the constraints (lines beginning with "-"). These constraints are then essentially ANDed together since they are comma separated when converted to DRL. Since they are called constraints, this makes sense. My question is this: Is there a similar way to allow a variable number of "constraints" that are all ORed ("||") together? I've been reading the documentation and searching mail archives and so far haven't found anything helpful. Let me know if there is a way to do this or any clever workarounds, since I don't want to delineate every possible combination of attributes when OR is needed. reid
