Clarify Transportation geometry types #208

Open balazsdukai opened 1 month ago

balazsdukai commented 1 month ago

I stumbled on the Transportation geometry types several times already, so I made it clear in the specs.

Related to the geometry types, I made an overview table, because I often have to dig through the specs for the allowed geometry types for each CityObject and it's easy to get things mixed up. I haven't added to the specs, because it would duplicate the info that is already in there. Or what do you think? I made the table by parsing the schemas with a python script.
