Whilst the model shows the association to the classes of the MetadataStructureDefinition, this is for conceptual purposes to show the link to the MetadataStructureDefinition. In the actual MetadataSet, as exchanged, there must, of course, be a reference to the MetadataStructureDefinition and optionally a Metadataflow or a MetadataProvisionAgreement, but the MetadataStructureDefinition is not necessarily exchanged with the metadata.
