Eps fhir resourceType CommunicationRequest further documentation request

Hello we are integrating with eps fhir download prescription and i would like more information about the resource type CommunicationRequest.

There is a payload section which has a array with a content string and a content reference. My questions are

  • is there always going to be a contentStringand a contentReference

  • will they always be in that order

  • is it possible to have 2 contentString then 1 contentReference in that case do the 2 content strings share the same content reference

  • is it possible to have 1 contentString then 2 contentReference in that case does the 1 content string apply to both content references
