"spherical_cs": { }

"$comment": "[RL] Definition to be completed. The definition should constrain a spherical CS to have 2 or 3 axes.
When a spherical CS is used within a geodetic CRS, 19111/Topic2 constrains axis names (see Topic 2 Table 27). WKT2 requires that axis abbreviations be from the Latin character set and recommends that axis abbreviations φ and θ are be replaced by U and V."

Beginne mit dem „spherical_cs“-Fragment im Issue und dem verlinkten ProjJson v0-7-Dokument. Prüfe 19111/Topic2 Table 27 und die dort referenzierten WKT2-Richtlinien zu Achsenabkürzungen; die Definition ist abgeschlossen, wenn sie sphärische Koordinatensysteme auf zwei oder drei Achsen beschränkt und die anwendbaren Benennungsregeln dokumentiert.
