|Description||string||This association describes a predecessor-successor relationship between a MeterService and one or more ConditioningService objects that process traffic from the meter. For example, for devices that implement preamble marking, the FollowingService reference (after the meter) is a PreambleMarkerService - to record the results of the metering in the preamble.
It might be expected that the NextServiceAfterMeter association would subclass from NextService. However, meters are 1:n fan-out elements, and require a mechanism to distinguish between the different results/outputs of the meter. Therefore, this association defines a new key property, MeterResult, which is used to record the result and identify the output through which this traffic left the meter.
