The official legal status of each kind of restricted area defines the kind of restriction(s), e.g. the restriction for a `game preserve’ may be ‘entering prohibited’, the restriction for an ‘anchoring prohibition area’ is ‘anchoring prohibited’.
Values 2, 3, 15, 16 and 17 have been transferred to the attribute restriction (RESTRN).
Value number 11 has been replaced by the object class inshore traffic zone (ISTZNE).
Value 13 should be encoded using object class caution area (CTNARE).

For reasons of backward compatibility with Edition 3.1, these new S-57 3.1.1 attribute values must have their meaning described in the attributes INFORM or TXTDSC. For consistency, when one or both of these attributes is used, the text must commence with the name of the feature, 'Environmentally Sensitive Sea Area' or 'Particularly Sensitive Sea Area'.
