S3.1. Observations that apply to a person other than the patient

The default assumption about any statement is that it applies to the patient. Where this is not the case an instance of ObservationStatement must include an instance of ObservationStatement/subject that refers to the person who is the subject of the observation. The subject may be a named individual but will often be an unnamed person with a specified relationship to the patient (e.g. a family member).  Therefore, this construct is used to represent various types of observations such as:

These attributes listed in the table below are used as described for the following classes.
