Road network format abstraction from OpenDRIVE

Describe the feature

At the moment the possible position types are quite coupled with the OpenDRIVE format (RoadPosition, LanePosition). In OSC 1.1 already a first approach was made to support also other formats like NDS by introducing GeoPosition (lat/lon/alt). Now it might be good to have positions defined, which are independent of the / compatible with any underlying road network.

Describe the solution you would like

Examples could be a position which refers to a road network model, which is compatible with several underlying road network models.

Additional context

In the OSC 2 project the domain model group (Rich Heidtman) is also working on this topic and the work must be synchronized. First we must identify if they really work on the same issue and how they see it. Maybe this is also going too far or in a wrong direction and there's no / a different requirement. Clarification will be part of this issue.
