This is the CodeSystem that contains codes in both MdfHmdRowType (http://terminology.hl7.org/CodeSystem/v3-MdfHmdRowType) and MdfHmdRowType (http://terminology.hl7.org/CodeSystem/v3-MdfHmdRowType).
Properties
This code system defines the following properties for its concepts
| Name | Code | URI | Type | Description |
| Status | status | http://hl7.org/fhir/concept-properties#status | code | Designation of a concept's state. Normally is not populated unless the state is retired. |
| Status | status | http://hl7.org/fhir/concept-properties#status | code | Designation of a concept's state. Normally is not populated unless the state is retired. |
Concepts
This code system http://hl7.org/fhir/comparison/CodeSystem/c5ecab15-a0f9-4fdf-9d87-bde1e84b2f11-2391 defines codes, but no codes are represented here
| Code | Display | Definition | Status | Status |
| assoc | Association Row | Identifies an association leading from the "class" (or association) that is most directly above this row | active, active | active, active |
| attr | Attribute Row | Identifies an attribute of the "class" (or association) that is most directly above this row. | active, active | active, active |
| class | HMD root class | Identifies "class" in the HMD. There is only one class entry in a Hierarchical Message Definition. This is the root class for the message. | active, active | active, active |
| hmd | HMD identifier | Always the first row of the table, identifies the particular Hierarchical Message Definition in the nomenclature of the HL7 Repository. | active, active | active, active |
| item | Collection Item Row | Identifies a message element that represents one of whatever is repeated in a collection | active, active | active, active |
| stc | Subtype constraint | This row corresponds to a subcomponent of the row above; it would not normally be included in an HMD, but it is included in order to be able to state a constraint on the subtype. This is explained in 10.2.2.4. | active, active | active, active |
