        v: Element `CodeSystem.text` is mapped to FHIR R4B element `CodeSystem.text` as `Equivalent`. Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.

        v: Element `CodeSystem.contained` is mapped to FHIR R4B element `CodeSystem.contained` as `Equivalent`. This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.

        v: Element `CodeSystem.url` is mapped to FHIR R4B element `CodeSystem.url` as `Equivalent`. Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version. The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in [Technical and Business Versions](https://hl7.org/fhir/resource..html#versions). In some cases, the resource can no longer be found at the stated url, but the url itself cannot change. Implementations can use the [meta.source](https://hl7.org/fhir/resou.html#meta) element to indicate where the current master source of the resource can be found.

        v: Element `CodeSystem.identifier` is mapped to FHIR R4B element `CodeSystem.identifier` as `Equivalent`. Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this code system outside of FHIR, where it is not possible to use the logical URI. Note that HL7 defines at least three identifiers for many of its code systems - the FHIR canonical URL, the OID and the V2 Table 0396 mnemonic code.

  comment:
    v: Element `CodeSystem.versionNeeded` is mapped to FHIR R4B element `CodeSystem.versionNeeded` as `Equivalent`. Best practice is that code systems do not redefine concepts, or that if concepts are redefined, a new code system definition is created. But this is not always possible, so some code systems may be defined as 'versionNeeded'. Most code systems occasionally refine the displays defined for concepts between versions. Contexts in which the concept display values are validated may require that the version be specified for some code systems irrespective of the value of this property.

    v: Element `CodeSystem.supplements` is mapped to FHIR R4B element `CodeSystem.supplements` as `Equivalent`. The most common use of a code system supplement is to add additional language support.

    v: Element `CodeSystem.filter` is mapped to FHIR R4B element `CodeSystem.filter` as `Equivalent`. Note that filters defined in code systems usually require custom code on the part of any terminology engine that will make them available for use in value set filters. For this reason, they are generally only seen in high value published terminologies.

    v: Element `CodeSystem.concept.designation` is mapped to FHIR R4B element `CodeSystem.concept.designation` as `Equivalent`. Concepts have both a ```display``` and an array of ```designation```.
