bound_crs and abridged_transformation - should they be included in an OGC CRS JSON encoding?

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.

The concepts of bound_crs and abridged_transformation are not recognised in Topic 2 (18-005r8) but are defined in CRS WKT (18-010r11). Should they be included in an OGC CRS JSON encoding?

Leggere il materiale estratto da ProjJson v0-7 RL 2024-06-16.docx, quindi confrontare i riferimenti a Topic 2 e CRS WKT citati nell’issue. Determinare se bound_crs e abridged_transformation appartengono alla codifica OGC CRS JSON e documentare la decisione di specifica concordata; non sono menzionati test né punti di ingresso per l’implementazione.
