This issue is extracted from the document submitted by Roger Lott at https://github.com/opengeospatial/CRS-JSON-Encoding/blob/main/ProjJson%20v0-7%20RL%202024-06-16.docx for discussion at the CRS SWG meeting OGC held during the Montreal June 2024 TC meeting.

"affine_cs": { }

*"$comment": "[RL] Definition to be completed. The definition would constrain an affine CS to have 2 or 3 axes."

Depends on #63: may need a change of approach, replacing subtype by type (as in the rest of PROJJSON) or by entityType (as in OGC 24-017).
