  "description": "Operation where default artifact version(s) can be specified.\\n\\nNOTE: Artifacts include FHIR Canonical resources and the resources specified as\\nnon-canonical resources, such as: Medication, Substance, MedicationKnowledge,\\nand Group.\\n\\n* `artifactVersion`: Specifies a version to use for a artifact resource if the artifact referencing the resource does not already specify a version. The format is the same as a canonical URL: `[url]|[version]` - e.g. `http://loinc.org|2.56`\\n* `checkArtifactVersion`: Edge Case: Specifies a version to use for a artifact resource. If the artifact referencing the resource specifies a different version, an error is returned instead of the package. The format is the same as a canonical URL: `[url]|[version]` - e.g. `http://loinc.org|2.56`\\n* `forceArtifactVersion`: Edge Case: Specifies a version to use for a artifact resource. This parameter overrides any specified version in the artifact (and any artifacts it depends on). The format is the same as a canonical URL: `[system]|[version]` - e.g. `http://loinc.org|2.56`. Note that this has obvious safety issues, in that it may result in a value set expansion giving a different list of codes that is both wrong and unsafe, and implementers should only use this capability reluctantly.",
