Constraints for Entry Values
The value of each Entry MUST have the same restrictions as the value of an observationobserved value of a property at a point in time. with representation of VALUE.
An Entry MAY be further constrained by the DataItem definition (see Device Information Model), for example a VariableDataSet having a string value MAY have a floating-point Temperature value. A restriction MUST NOT be broadened or removed, for example, the value “READY” MUST NOT occur with a TemperatureDataSet constrained to floating-point numbers.
The Device Information Model DataItem Definition MAY provide the type and units of an Entry for a key.
