[rules-users] Minor Issue in writing DSL

[Edson Tirelli]

   Drools respects encapsulation, so it works with javabean method name
conventions. If you have a method isApplication() that returns a boolean,
does not matter how your class calculates the return value. Same for any
other method. In 4.0, you can write:

ObjectA( application == true || banker == true )

   To map that as a DSL, just follow your usual procedure and syntax.
