Summary

0007577: IVI - logical problems with TractorCharacteristics and TrainCharacteristics types

Description

There are multiple logical problems with the TractorCharacteristics / TrailerCharacteristics / TrainCharacteristics types:
- what should happen if at the SEQUENCE OF VehicleCharacteristicsFixValues { CHOICE {...} } elements the same CHOICE is selected multiple times, but with different value assignments?
- what should happen if the same CHOICE and value types are selected for equalTo and notEqualTo fields?
- the logic of the 'ranges' element is hard to understand
- what should happen if TractorCharacteristics and TrainCharacteristics types are filled with inconsistent values?
The above dilemmas should not occur with properly written ASN.1 definitions, because the aim is ensure that valid messages are never logically inconsistent. I would redo these type definitions, and use just nested SEQUENCE structures.
