right now it's only "one level below the current one", but that makes no sense, does it?

If a "Building" has 3 "BuildingPart" and those have "BuildingInstallation" and then how are we supposed to link the installations to the BPart?

I'd say all the children

True, I missed this before. I would change the requirement then to:

must have one member with the name "CityObjects". The value of this member is a collection of key-value pairs, where the key is the ID of the object, and the value is one City Object. The ID of a City Object should be unique (within one CityJSONFeature Object), and all the children of the "CityJSONFeature" must be listed.

made it clearer that all under are included, and added this to the snippet

must have one member with the name "CityObjects". The value of this member is a collection of key-value pairs, where the key is the ID of the object, and the value is one City Object. The ID of a City Object should be unique (within one "CityJSONFeature"), and all the children of the "CityJSONFeature" must be included (and the children of the children (recursively), if there are any).
