Can "or" precondition allow more than 2 parameters

[ipa-rwu]

For example I create an action as

    (:durative-action move-wp
        :parameters (?w - workpiece ?cur ?nxt - position)
        :duration (= ?duration 1)
        :condition (and
            (at start (at ?w ?cur))
            (at start (clear ?nxt))
            (at start (or
                (and (= ?cur p1) (= ?nxt p2))  ;; Move from P1 to P2
                (and (= ?cur p2) (= ?nxt p3)) ;; Move from P2 to P3
                (and (= ?cur p3) (= ?nxt p4))
            ))
        )
        :effect (and
            (at end (not (at ?w ?cur)))
            (at end (at ?w ?nxt))
        )
    )

It seems that "or" only accept 2 paramters. https://github.com/PlanSys2/ros2_planning_system/blob/rolling/plansys2_pddl_parser/include/plansys2_pddl_parser/Or.h#L14-L17

class Or : public Condition {

```cpp
public:
    Condition *first, *second;

    Or()
        : first( 0 ), second( 0 ) {}

Is it possible to accept more than 2?
