ServiceJourneyInterchange points to ServiceJourney via VehicleJourneyRefStructure

[skinkie]

I think it would again be in hour best interest that VehicleJourneyRefStructure and the consequence that it is basically unknown from which type the Journey originates from is avoided. I understand that from_something and to_something in its short hand form cannot specify a type, but I would then rather see that we have <To> and <From> which receive an abstract substitution group that expilictly use a ServiceJourneyRef, etc.

@Aurige what to do?
