// status: draft

uses "http://hl7.org/fhir/StructureDefinition/Condition" alias Condition as source
uses "https://www.senologie.org/fhir/StructureDefinition/obds-meldung" alias OBDSMeldung as target

// Known limitation: MapTumorzuordnung uses `target tgt : BackboneElement`
// because FML has no syntax to declare the Logical Model sub-path for
// BackboneElement slices. The IG Publisher produces SM_TARGET_PATH errors (~5).
// Element names are correct per the oBDS Logical Model.
// ============================================================================
// Tumorzuordnung: Condition (Diagnose) -> OBDSMeldung.tumorzuordnung
// Wird von allen Meldungstypen importiert, da die Tumorzuordnung in jeder
// oBDS-Meldung enthalten sein muss.
