Additional information such &quot;released&quot;, &quot;signed&quot;, etc would be represented using [Provenance](provenance.html) which provides not only the act but also the actors and dates and other related data. These act states would be associated with an observation status of `preliminary` until they are all completed and then a status of `final` would be applied.</td></tr><tr><td><a href="http://hl7.org/fhir/R4/codesystem-observation-status.html#observation-status-amended">amended</a></td><td>Amended</td><td>Subsequent to being Final, the observation has been modified subsequent.
