An optional relatedResource property lists objects, each with a unique required id and a digestSRI or digestMultibase value, allowing verifiers to check that retrieved resources such as contexts or images have not changed; a conforming verifier that retrieves such a resource must compute its digest and produce an error on mismatch, and sha384 should be the minimum strength hash.
