|---|---|---|---|---|
| exponent | Integer | 0..1 | Defines the exponent with which this unit instance should be used. In order to define square meters for example, the SIUnit "metre" with an exponent of 2 will be used. If no exponent is defined it is equivalent to the value 1. |
Unit |
| unEceCode | String | 0..1 | The UNECE provides a list of "Codes for Units of Measurement used in the International Trade". This attribute shall be used for traceability of Units defined in the VEC into the UNECE system only. It provides additional meta information about the unit, but shall not be used as the only definition of a Unit. Specifying a UNECE code does not exempt the creating system from generating a correct VEC mapping of the corresponding unit. In case of doubt, the VEC mapping has priority. |
