Authorization Policy vNext -> Nested Table References #569
Description
To further enhance the authorization policy capability, add the ability to map to nested tables/columns. For example:
- Database Policy: Entity (book)
"New Starch Press" eq @item().publisher_id.name
Because the policy is applied to the book entity, the nested policy will search the Publishers table using publisher_id to acquire the record where name column is "New Starch Press"
Nesting will apply to the @item "Policy Expression System Object" described in the request authorization RFC.
