value set `http://hl7.org/fhir/ValueSet/variable-handling|5.0.0` as defined in FHIR R5
in FHIR R4.

The source value set is bound to the following FHIR R5 elements:
* `Evidence.statistic.modelCharacteristic.variable.handling` as Required
* `EvidenceVariable.handling` as Required

Across FHIR versions, the value set has been mapped as:
* `http://hl7.org/fhir/ValueSet/variable-handling|5.0.0`
* `http://hl7.org/fhir/ValueSet/variable-handling|4.3.0`

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).
FHIR ValueSet `http://hl7.org/fhir/ValueSet/variable-handling|5.0.0`, defined in FHIR R5 does not have any mapping to FHIR R4"/>
