        v: Element `StructureDefinition.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 `StructureDefinition.text` do not cover the following types: Narrative. The mappings for `StructureDefinition.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 `StructureDefinition.identifier` do not cover the following types: Identifier. The mappings for `StructureDefinition.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 structure definition outside of FHIR, where it is not possible to use the logical URI.

A StructureDefinition does not need to specify the target it applies to,as StructureDefinitions will often be valid across multiple versions of FHIR. FHIR tooling can determine whether a StructureDefinition is consistent with a particular StructureDefinition if desired.

    v: Element `StructureDefinition.abstract` is mapped to FHIR R4B element `StructureDefinition.abstract` as `Equivalent`. Abstract Resources cannot be instantiated - a concrete sub-type must be used. Abstract datatypes and extensions cannot be used in an instance. For logical models, the exact implication of "abstract" will rest with the author, depending how the logical model is used. Flagging a constraint structure as abstract conveys design intent but makes no difference to how the structure definition is handled. Note that inline declared elements that are given the type "Element" in the profile, but have children described, are anonymous concrete types that specialise Element.

    v: Element `StructureDefinition.context` is mapped to FHIR R4B element `StructureDefinition.context.expression` as `SourceIsBroaderThanTarget`. If the context is an element that can have multiple types, then use (e.g.) value[x] if the extension works on all choice types, or otherwise an enumeration of explicitly named elements if not. Note that a context of "string" doesn't mean that the extension can be used with one of the string patterns such as "id" etc.

The mappings for `StructureDefinition.type` do not cover the following types: code. The mappings for `StructureDefinition.type` do not cover the following types based on type expansion: value. Note that in the case of constraints, the type could be determined by chasing through the baseDefinition references until a concrete structure (derivation = specialization) is reached, or by looking at the path of the first element in the snapshot - if present - but providing the type directly makes for simpler tooling and indexing.

    v: Element `StructureDefinition.baseDefinition` is mapped to FHIR R4B element `StructureDefinition.baseDefinition` as `Equivalent`. If differential constraints are specified in this structure, they are applied to the base in a "differential" fashion. If there is no base, then the differential constraints cannot be provided (snapshot only). Differential structures are useful for the editing perspective, and snapshot structures are suitable for operational use. The FHIR Project provides a number of tools/services to populate snapshots from differential constraints. Logical Models have a base of "Element" or another logical model.

    v: Element `StructureDefinition.derivation` is mapped to FHIR R4B element `StructureDefinition.derivation` as `Equivalent`. If the definition is a specialization, then it adds new elements in the differential, and the snapshot includes the inherited elements. If the definition is a constraint, then it can not define new elements, it can only make new rules about existing content (see [Profiling Resources](https://hl7.org/fhir/profiling..html#resources)).

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.
