Returns the schema used when adding an arbitrary new field to an object. When no schema is
provided at all the editor is unconstrained, so additions are allowed; once a schema is provided,
additions are only allowed when the schema explicitly opts in via additionalProperties: true or
an additionalProperties sub-schema. This is stricter than JSON Schema's true default — UI
authors must opt in.
