This field indicates to the application that a resource is required for a different amount of time than the appointment's overall duration. An unvalued duration indicates that the resource is required from its start date/time offset (specified in the previous two fields) until the end of the appointment. If no start date/time offset is specified, then the resource is required for the full duration of the appointment.\r\n\r\nThis field must be a positive, non-zero number.  A negative number or zero (0) is nonsensical in the context of a duration.",
