        v: Element `DataElement.language` is mapped to FHIR R4B element `StructureDefinition.language` as `Equivalent`. Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).

The mappings for `DataElement.text` do not cover the following types: Narrative. The mappings for `DataElement.text` do not cover the following types based on type expansion: div, status. Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded in formation is added later.

The mappings for `DataElement.identifier` do not cover the following types: Identifier. The mappings for `DataElement.identifier` do not cover the following types based on type expansion: assigner, period, system, type, use, value. Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, e.g., to identify this data element outside of FHIR, where it is not possible to use the logical URI.

The publisher (or steward) of the data element is the organization or individual primarily responsible for the maintenance and upkeep of the data element. This is not necessarily the same individual or organization that developed and initially authored the content. The publisher is the primary point of contact for questions or issues with the data element. This item SHOULD be populated unless the information is available from context.

      v: Element `DataElement.text` is mapped to FHIR R4B element `StructureDefinition.text` as `SourceIsBroaderThanTarget`. The mappings for `DataElement.text` do not cover the following types: Narrative. The mappings for `DataElement.text` do not cover the following types based on type expansion: div, status. Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded in formation is added later.

      v: Element `DataElement.identifier` is mapped to FHIR R4B element `StructureDefinition.identifier` as `SourceIsBroaderThanTarget`. The mappings for `DataElement.identifier` do not cover the following types: Identifier. The mappings for `DataElement.identifier` do not cover the following types based on type expansion: assigner, period, system, type, use, value. Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, e.g., to identify this data element outside of FHIR, where it is not possible to use the logical URI.

      v: Element `DataElement.stringency` has a context of StructureDefinition based on following the parent source element upwards and mapping to `StructureDefinition`. Element `DataElement.stringency` has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element).

      v: Element `DataElement.element` is mapped to FHIR R4B element `StructureDefinition.differential.element` as `SourceIsBroaderThanTarget`. The mappings for `DataElement.element` do not cover the following types: ElementDefinition. The mappings for `DataElement.element` do not cover the following types based on type expansion: aggregation, alias, base, binding, code, comment, condition, constraint, contentReference, defaultValue[x], definition, description, discriminator, example, expression, fixed[x], human, identity, isModifier, isSummary, key, label, language, map, mapping, max, maxLength, maxValue[x], meaningWhenMissing, min, minValue[x], mustSupport, ordered, orderMeaning, path, pattern[x], profile, representation, requirements, rules, severity, short, sliceName, slicing, source, strength, targetProfile, type, value[x], valueSet[x], versioning, xpath. For simple data types there will only be one repetition. For complex data types, multiple repetitions will be present defining a nested structure using the "path" element.
