[rules-users] cross products in excel decision tables

[Tom Eugelink]

I need to model something similar to "when the lastname on a passport does not match the lastname on the application" in a decision table. Written in DRL:

rule "PassportValidation_24"
     when
         $a : Application()
         $p : Passport(application == $a, lastName != $a.lastName)
     then
         $p.setError("Passport's last name (" + $p.getLastName() + ") does not match with application's last name (" + $a.getLastName() + ")");
end

How do I do such a cross referencing in an Excel decision table?
