Definition of "bearing" (missing)

NOTE: Markdown does not support highlighting in color, so bold/italic has been used to highlight the material being discussed. 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.

See "Points of discussion for axis" for first use of bearing and original comment for the missing bearing attribute definition

まず「Points of discussion for axis」の資料と、参照されているProjJson v0-7ドキュメントを読んで、bearingの最初の使用箇所を理解します。スキーマ定義を見つけ、必須のlongitudeとid/idsの相互排他ルールがissueと一致するように、提案されたbearingオブジェクトを追加します。不足している定義が存在し、meridianの定義と整合していれば完了です。
