Defines a standardized object whose properties represent the externally visible characteristics associated with the authentication and authorization process of an access controlled point. (e.g., door, gate, turnstile). Access through this point is directional in that it represents access in one direction only. A door, in which access is controlled in both directions, is represented by two separate Access Point objects.
