Is this intended to exchange data in context or to signal anchor changes?
In the case of signalling data in context, how do we handle parallel changes between multiple applications? This could trigger a message storm (they both try to merge the changes, sending updates on the update, which triggers a new merge, …)

Proposed Wording:

An array of named FHIR objects corresponding to the user's context after the given event has occurred. Common FHIR resources are: Patient, Encounter, ImagingStudy and List.
