dom-2 | error | MedicationRequest | If the resource is contained in another resource, it SHALL NOT contain nested Resources | `contained.contained.empty()`
dom-3 | error | MedicationRequest | If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource | `contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()`
dom-4 | error | MedicationRequest | If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated | `contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()`
dom-5 | error | MedicationRequest | If a resource is contained in another resource, it SHALL NOT have a security label | `contained.meta.security.empty()`
dom-6 | best practice | MedicationRequest | A resource should have narrative for robust management | `text.`div`.exists()`
