If the direction is defined for properties or tags, then • The Source To Target direction means that only the properties, which exist in the source element, will be treated as a result of this criterion. • The Target To Source direction means that only the properties, which exist in the target element, will be treated as a result of this criterion. • If the Both direction is chosen, the both above described cases will be treated as a valid result.
