+ * The WriteProperty service is used by a client BACnet-user to modify the 
+ * value of a single specified property of a BACnet object. This service 
+ * potentially allows write access to any property of any object, whether a 
+ * BACnet-defined object or not. Some implementors may wish to restrict write 
+ * access to certain properties of certain objects. In such cases, an attempt 
+ * to modify a restricted property shall result in the return of an error of 
+ * 'Error Class' PROPERTY and 'Error Code' WRITE_ACCESS_DENIED.
