In the notes of Appendix F it states:
```
Notes:
1. The various *_name attributes are optional but recommended when known as
they allow for a better description and interoperability with WKT definitions.
2. reference_ellipsoid_name, prime_meridian_name, horizontal_datum_name and
geographic_crs_name must be all defined if any one is defined, and if
projected_crs_name is defined then geographic_crs_name must be also.
```
If I have this WKT with undefined projected crs name and undefined geographic
CRS name:
```
PROJCRS["unknown",
BASEGEOGCRS["unknown",
DATUM["Unknown based on Normal Sphere (r=6370997) ellipsoid",

```
Is it recommended to represent with all `*_name` attributes with the missing
ones denoted as `undefined`:
```
projected_crs_name: 'undefined'
geographic_crs_name: 'undefined'
semi_major_axis: 6370997.0,
semi_minor_axis: 6370997.0,
inverse_flattening: 0.0,
reference_ellipsoid_name: 'Normal Sphere (r=6370997)',
longitude_of_prime_meridian: 0.0,
prime_meridian_name: 'Greenwich',
horizontal_datum_name: 'Unknown based on Normal Sphere (r=6370997) ellipsoid',
grid_mapping_name: 'oblique_mercator',
latitude_of_projection_origin: 0.0,
longitude_of_projection_origin: 13.809602948622212,
azimuth_of_central_line: 8.998112717187938,
scale_factor_at_projection_origin: 1.0,
false_easting: 0.0,
false_northing: 0.0
```
Or to remove all of the `*_name` attributes:
```
semi_major_axis: 6370997.0,
semi_minor_axis: 6370997.0,
inverse_flattening: 0.0,
longitude_of_prime_meridian: 0.0,
grid_mapping_name: 'oblique_mercator',
latitude_of_projection_origin: 0.0,
longitude_of_projection_origin: 13.809602948622212,
azimuth_of_central_line: 8.998112717187938,
scale_factor_at_projection_origin: 1.0,
false_easting: 0.0,
false_northing: 0.0
```
