rule base64BinaryEqualExample{
permit
condition base64.a == base64.b || base64BinaryEqual(base64BinaryOneAndOnly(base64.a),base64BinaryOneAndOnly(base64.b))
}This rule will return Permit if either (a) there is at least one value in bag a equal to bag b or (b) both bags contain one value exactly and the value in bag is equal to the value in bag b.
