704318007 | Property type |

This attribute is used to specify the type of inherent quality or process that is to be observed. Its values are abstract types of quality (length, odor, concentration) or abstract types of process features (rate, speed), and do not include qualities that are located (length of arm, odor of urine), or given a value (elevated concentration).
