Non-default CRS values are specified by any string that uniquely identifies a coordinate reference system associated with this type. To maximize interoperability, suggested (but not limited to) formats for CRS are: * `<projjson>` - A complete CRS definition embedded directly using the [PROJJSON](https://proj.org/en/stable/specifications/projjson.html) specification.
