The standard design file units loadout for al l OpenRoads and OpenRail products appears to be US Survey Ft. I would recommend adding an international ft. option to all seed files to match the current sunsetting of the US Survey Ft. in 2022.

BCI-I-659 is a related Idea, where all of the dgnlibs should adhere to MicroStation units behavior, then there is no need for seperate Imperial, Metric, International definitions.
I would also suggest the the US Global Coordinate systems be updated to reflect International Feet since the US Survey Foot has officially been depreciated.
