purpose:
  v: This extension is part of the cross-version definitions generated to enable use of the element `ValueSet.codeSystem` as defined in FHIR DSTU2 in FHIR R4B. The source element is defined as: `ValueSet.codeSystem` 0..1 `BackboneElement` Across FHIR versions, the element set has been mapped as: * DSTU2: `ValueSet.codeSystem` 0..1 `BackboneElement` * DSTU2: `ValueSet.codeSystem` 0..1 `BackboneElement` Following are the generation technical comments: Element `ValueSet.codeSystem` has a context of ValueSet based on following the parent source element upwards and mapping to `ValueSet`. Element `ValueSet.codeSystem` has a context of CodeSystem based on following the parent source element upwards and mapping to `CodeSystem`. Element `ValueSet.codeSystem` has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element).

      v: Element `ValueSet.codeSystem` has a context of ValueSet based on following the parent source element upwards and mapping to `ValueSet`. Element `ValueSet.codeSystem` has a context of CodeSystem based on following the parent source element upwards and mapping to `CodeSystem`. Element `ValueSet.codeSystem` has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element). All code systems defined as part of a FHIR value set have an implicit valueset that includes all of the codes in the code system - the value set in which they are defined.

comment:
  v: Element `ValueSet.codeSystem.system` is part of an existing definition because parent element `ValueSet.codeSystem` requires a cross-version extension. Element `ValueSet.codeSystem.system` has a context of ValueSet based on following the parent source element upwards and mapping to `ValueSet`. Element `ValueSet.codeSystem.system` has a context of CodeSystem based on following the parent source element upwards and mapping to `CodeSystem`. Element `ValueSet.codeSystem.system` has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element). The reference is not required to point to any specific kind of definition, but the more information that can be provided, the more useful it is for implementers. Best practice is to resolve to a computable definition of the code system (either a value set, or some other format). Terminology servers MAY validate this reference (e.g. when accepting PUT/POST), and MAY make additional rules about what kind of content it refers to.

definition:
  v: May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
comment:
  v: There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

comment:
  v: Element `ValueSet.codeSystem.caseSensitive` is part of an existing definition because parent element `ValueSet.codeSystem` requires a cross-version extension. Element `ValueSet.codeSystem.caseSensitive` has a context of ValueSet based on following the parent source element upwards and mapping to `ValueSet`. Element `ValueSet.codeSystem.caseSensitive` has a context of CodeSystem based on following the parent source element upwards and mapping to `CodeSystem`. Element `ValueSet.codeSystem.caseSensitive` has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element). If this value is missing, then it is not specified whether a code system is case sensitive or not. When the rule is not known, Postel's law should be followed: produce codes with the correct case, and accept codes in any case. This element is primarily provided to support validation software.

Element `ValueSet.codeSystem.concept.abstract` has a context of CodeSystem based on following the parent source element upwards and mapping to `CodeSystem`.

  v: Element `ValueSet.codeSystem.concept.designation` is part of an existing definition because parent element `ValueSet.codeSystem.concept` requires a cross-version extension.

comment:
  v: Element `ValueSet.codeSystem.concept.designation.value` is part of an existing definition because parent element `ValueSet.codeSystem.concept.designation` requires a cross-version extension. Element `ValueSet.codeSystem.concept.designation.value` has a context of ValueSet based on following the parent source element upwards and mapping to `ValueSet`. Element `ValueSet.codeSystem.concept.designation.value` has a context of CodeSystem based on following the parent source element upwards and mapping to `CodeSystem`. Element `ValueSet.codeSystem.concept.designation.value` has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element).
