Generated Narrative: CodeSystem resource-aggregation-mode

This case-sensitive code system http://hl7.org/fhir/resource-aggregation-mode defines the following codes in an undefined hierarchy:

Lvl	Code	Display	Definition
1	contained	Contained	The reference is a local reference to a contained resource.
1	referenced	Referenced	The reference to a resource that has to be resolved externally to the resource that includes the reference.
2	bundled	Bundled	When the resource is in a Bundle, the resource the reference points to will be found in the same bundle as the resource that includes the reference.
