This property is an array of BACnetDeviceObjectPropertyReference that defines the members of the current Structured View.

By including references to 'child' Structured View objects, multilevel hierarchies may be created.

If the optional device identifier is not present for a particular Subordinate_List member, then that object must reside in the same device that maintains the Structured View object. To avoid recursion, it is suggested that a single Structured View object should be referenced only once in the hierarchy. If the size of the Subordinate_List array is changed, the size of the Subordinate_Annotations array, if present, shall also be changed to the same size.
