#414 Unit of Measure for Ranges in a LimitAlertCondition

[Clément Ledoux]

This ticket is created based on APKP discussions (https://github.com/ornet-ev/apkp/issues/36):

Do we need such a requirement to provide more information about the Units of Measure for Ranges in a LimitAlertCondition?

To assure that the unit of the limits in pm:Range is the unit of the referenced pm:AlertConditionDescriptor/pm:Source, an SDC ALERT PROVIDER shall assure that the following is true:

If there is no pm:Source that is a Metric with a UOM, there is no pm:Range in the pm:AlertConditionDescriptor or pm:AlertConditionState
There is only one pm:Source with a UOM or multiple pm:Source with the same UOM for a pm:AlertConditionDescriptor or pm:AlertConditionState that contains a pm:Range.
Similarly for an operation:

If there is no @OperationTarget that is an pm:AlertConditionDescriptor where the UOM can be derived from the pm:Source, there is no pm:Range in the pm:SetValueOperationState
