Existing Wording: The corresponding reverse relationship from the target to the source exists in a logical sense, but is not represented explicitly in the target resource.

Proposed Wording: The corresponding reverse relationship from the target to the source exists in a logical sense, but is not typically represented explicitly in the target resource.

Comment:

I don't think there is a strict requirement that this circular relationship doesn't exist, which leads me to my proposed wording change. For example, MedicationRequest A can reference MedicationRequest B, which can reference MedicationRequest A again. Another example: Condition.detail -> MedicationRequest.supportingInformation -> Goal.addresses -> Condition again.

Found documentation indicating that circular resource references are allowed. Perhaps reference/relate to references.html#2.3.0.7 somehow

Summary:

Circular relationship between resources
