| Title | Cross-version ValueSet DSTU2.UnknownContentCode for use in FHIR R4B |
| Realm | uv |
| Authority | hl7 |
| Description | This cross-version ValueSet represents content from `http://hl7.org/fhir/ValueSet/unknown-content-code|1.0.2` for use in FHIR R4B. |
| Purpose | This value set is part of the cross-version definitions generated to enable use of the
value set `http://hl7.org/fhir/ValueSet/unknown-content-code|1.0.2` as defined in FHIR DSTU2
in FHIR R4B.
The source value set is bound to the following FHIR DSTU2 elements:
* `Conformance.acceptUnknown` as Required
Across FHIR versions, the value set has been mapped as:
* `http://hl7.org/fhir/ValueSet/unknown-content-code|1.0.2`
* `http://hl7.org/fhir/ValueSet/unknown-content-code|3.0.2`
* `http://hl7.org/fhir/ValueSet/unknown-content-code|4.0.1`
Note that all concepts are included in this cross-version definition because no concepts have compatible representations
Following are the generation technical comments:
All concepts in the comparison are listed as identical.
The source and target value sets have the same number of active concepts (4).
All concepts in the comparison are listed as identical.
