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

Start by reading the "Points of discussion for axis" material and the referenced ProjJson v0-7 document to understand the first use of bearing. Locate the schema definitions and add the proposed bearing object so its required longitude and mutually exclusive id/ids rules match the issue; done means the missing definition is present and consistent with the meridian definition.
