/** @defgroup DSWP Data Sharing - Write Property Multiple Service (DS-WPM)
 * @ingroup DataShare
 * 15.10 WriteProperty Multiple Service <br>
 * The WritePropertyMultiple service is used by a client BACnet-user
 * to modify the value of one or more specified properties of a BACnet object.
 * This service potentially allows write access to any property of any object,
 * whether a BACnet-defined object or not.
 * Properties shall be modified by the WritePropertyMultiple service
 * in the order specified in the 'List of Write Access Specifications'
 * parameter, and execution of the service shall continue until all of the
 * specified properties have been written to or a property is encountered that
 * for some reason cannot be modified as requested.
 * Some implementers 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. Note that these restricted properties may be
 * accessible through the use of Virtual Terminal services or other means at the
 * discretion of the implementer.
