| | DirectionalAttribute | The subclass of PositionalAttributes that concern compass directions. |
| | RotationalAttribute | A PositionalAttribute characterizing the direction of Rotating. |

| Instances | Above | This is a PositionalAttribute derived from the up/down schema and not involving contact. Note that this means directly above, i.e., if one object is Above another object, then the projections of the two objects overlap. |
| | Below | This PositionalAttribute is derived from the up/down schema and may or may not involve contact. Note that this means directly below, i.e., if one object is Below another object, then the projections of the two objects overlap. |
