Dealing with default behavior from OSC1

When migrating a concrete scenario from OSC1 to OSC2, the result should be a concrete OSC2 scenario. This would require specifying all possible parameters according to https://www.asam.net/static_downloads/public/asam-openscenario/2.0.0/conceptual-overview/scenario-abstraction.html#sec-global-terminology-logical_scenario How would this be treated in the migration? How would "all possible parameters" be specified in the migration?

Example from OSC1: If I let a vehicle accelerate to 50 km/h with a SpeedAction, and define no further actions after that, it should (by default) continue traveling at this speed.

Is it defined somewhere what should happen in this situation in an OSC2 scenario?
