[x3d-public] CollisionSensor > collider or collidables?

[doug sanden]

Q. are a few samples wrong?
http://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/components/rigid_physics.html#CollisionSensor
- Specs: CollisionSensor->collider field takes collisionCollection

- Examples differ, putting CollisionCollection into CollisionSensor->collidables field:
1.
http://www.xj3d.org/extensions/rigid_physics_examples.html
- xj3d Ball_Bounce.x3dv:
DEF COLLISION-OUTPUT CollisionSensor {
  collidables USE COLLISION-GROUP
}

2.
http://www.web3d.org/x3d/content/examples/Basic/#RigidBodyPhysics
BallBounce.x3d and BallBounceSimple.x3d show collisionCollection containerField='collidables'
    <CollisionSensor DEF='COLLISION-OUTPUT'>
      <CollisionCollection DEF='COLLISION-GROUP' appliedParameters='"BOUNCE"' bounce='1.0' containerField='collidables' minBounceSpeed='1.0'>
