This is the CodeSystem that contains all the codes in AlternativeCodeKind (http://terminology.hl7.org/CodeSystem/composition-altcode-kind) and AlternativeCodeKind (http://terminology.hl7.org/CodeSystem/composition-altcode-kind). E.g. what you have to deal with if you get resources containing codes in either of them
This code system http://hl7.org/fhir/comparison/CodeSystem/79ef1cfb-ecb3-468a-b7e1-93fd79025b05-752 defines codes, but no codes are represented here
| Code | Display | Definition |

| case-insensitive | Case Insensitive | The code is an alternative to be used when a case insensitive code is required (when the primary codes are case sensitive). |
| case-sensitive | Case Sensitive | The code is an alternative to be used when a case sensitive code is required (when the primary codes are case insensitive). |
