Points from a record known to be incorrect to the record that carries the corrected information.

Overview

Answers the question a reader holding a wrong record cannot otherwise answer: where is the right one? R4 gives DocumentReference a relatesTo for this and gives most other resource types nothing, so this extension is how the link is carried uniformly.

Does not say the record is wrong -- the resource's own status element does that -- and does not replace version history, which remains the record of what changed and when.
