QuantityKind
A QuantityKind is any observable property that can be measured and quantified numerically. Familiar examples include physical properties such as length, mass, time, force, energy, power, electric charge, etc. A quantity (not represented as class in the VEC) would always be associated with the context of measurement (i.e. the thing measured, the measured value, the accuracy of measurement, etc.) whereas the underlying QuantityKind is independent of any particular measurement.
A QuantityKind provides an identifier and an optional human-readable name and is associated with a Unit that specifies how magnitudes of this QuantityKind are expressed within this VEC.

| identification | String | 1 | Specifies a unique identification of the QuantityKind. The identification is guaranteed to be unique within a VEC. Furthermore, the same QuantityKind shall have the same Identification for different VECs in the same a data exchange context. For example, if using the identification | QuantityKind |
