Official URL: https://haau3.com/fhir/StructureDefinition/haau3-communication Version: 1.0.0
Draft as of 2026-10-14 Computable Name: Haau3Communication

A record that information was communicated about a care recipient. Delivered exactly as it arrived, and current sources send very little: the records seen so far carry only a status and a subject, with no message content, sender, recipient or time. Treat the presence of a record as the fact, not as a message to read.
