Definition of "object_usage"

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.

"$comment": "[RL] See comments regarding usage under compound_crs and usages."

Review the proposed object_usage schema and the referenced definitions for bbox, vertical_extent, temporal_extent, id, ids, usages, and id_ids_mutually_exclusive. Compare it with the linked ProjJson v0-7 document and the comments referenced under compound_crs and usages; done requires an agreed definition from the CRS SWG discussion and a consistent schema update.
