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).

      comment:
        v: Element `Questionnaire.text` is mapped to FHIR R4 element `Questionnaire.text` as `Equivalent`. 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 publisher (or steward) of the questionnaire is the organization or individual primarily responsible for the maintenance and upkeep of the questionnaire. 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 questionnaire. This item SHOULD be populated unless the information is available from context.

This description can be used to capture details such as why the questionnaire was built, comments about misuse, instructions for clinical use and interpretation, literature references, examples from the paper world, etc. It is not a rendering of the questionnaire as conveyed in the 'text' field of the resource itself. This item SHOULD be populated unless the information is available from context (e.g. the language of the profile is presumed to be the predominant language in the place the profile was created).

    v: Element `Questionnaire.effectivePeriod` is mapped to FHIR R4 element `Questionnaire.effectivePeriod` as `Equivalent`. The effective period for a questionnaire determines when the content is applicable for usage and is independent of publication and review dates. For example, a measure intended to be used for the year 2016 might be published in 2015.

  comment:
    v: Element `Questionnaire.item.definition` is mapped to FHIR R4 element `Questionnaire.item.definition` as `Equivalent`. the URI refers to an ElementDefinition in either a [StructureDefinition](https://hl7.org/fhir/s.html#) or a [DataElement](https://hl7.org/fhir/d.html#), and always starts with the canonical URL for the target resource. When referring to a StructureDefinition, a fragment identifier is used to specify the element definition by its id [Element.id](https://hl7.org/fhir/element-def.html#Element.id). E.g. http://hl7.org/fhir/StructureDefinition/Observation#Observation.value[x]. In the absence of a fragment identifier, the first/root element definition in the target is the matching element definition. Note that [LOINC codes](https://hl7.org/fhir/loinc.html#da.html#dataelements) implicitly define DataElement resources.

    v: Element `Questionnaire.item.prefix` is mapped to FHIR R4 element `Questionnaire.item.prefix` as `Equivalent`. These are generally unique within a questionnaire, though this is not guaranteed. Some questionnaires may have multiple questions with the same label with logic to control which gets exposed. Typically these won't be used for "display" items, though such use is not prohibited. Systems SHOULD NOT generate their own prefixes if prefixes are defined for any items within a Questionnaire.

    v: Element `Questionnaire.item.enableWhen` is mapped to FHIR R4 element `Questionnaire.item.enableWhen` as `Equivalent`. If multiple repetitions of this extension are present, the item should be enabled when the condition for *any* of the repetitions is true. I.e. treat "enableWhen"s as being joined by an "or" clause. This element is a modifier because if enableWhen is present for an item, "required" is ignored unless one of the enableWhen conditions is met.

The mappings for `Questionnaire.item.enableWhen.answer[x]` do not cover the following types: Attachment. The target context `Questionnaire.item.enableWhen.answer[x]` is a choice-type element and cannot directly hold extensions. The context is moved up to parent element `Questionnaire.item.enableWhen`. Multiple answers are treated as "or". E.g. Enable if question 1 = A, C or E. Components not specified in the answer do not need to match. For example, if enableWhen specifies code + system for a Coding, it is ok if the answer has a "display" element. I.e. treat the answer as a 'pattern'. The dataType of this element must be the same as the data type of the question being referenced.

    v: Element `Questionnaire.item.required` is mapped to FHIR R4 element `Questionnaire.item.required` as `Equivalent`. Questionnaire.item.required only has meaning for elements that are conditionally enabled with enableWhen if the condition evaluates to true. If an item that contains other items is marked as required, that does not automatically make the contained elements required (though required groups must contain at least one child element). The value may come from the ElementDefinition referred to by .definition.

    v: Element `Questionnaire.item.repeats` is mapped to FHIR R4 element `Questionnaire.item.repeats` as `Equivalent`. If a question is marked as repeats=true, then multiple answers can be provided for the question in the corresponding QuestionnaireResponse. When rendering the questionnaire, it is up to the rendering software whether to render the question text for each answer repetition or to simply list each of the answers beneath the question. (Which is most appropriate visually may depend on the type of answer as well as whether there are nested items.). The value may come from the ElementDefinition referred to by .definition.

    v: Element `Questionnaire.item.readOnly` is mapped to FHIR R4 element `Questionnaire.item.readOnly` as `Equivalent`. The value of readOnly elements can be established by asserting extensions for defaultValues, linkages that support pre-population and/or extensions that support calculation based on other answers.

    v: Element `Questionnaire.item.maxLength` is mapped to FHIR R4 element `Questionnaire.item.maxLength` as `Equivalent`. For base64binary, reflects the number of characters representing the encoded data, not the number of bytes of the binary data.

    v: Element `Questionnaire.item.option` is mapped to FHIR R4 element `Questionnaire.item.answerOption` as `Equivalent`. This element can be used when the value set machinery of options is deemed too cumbersome or when there's a need to capture options that are not codes.

    v: Element `Questionnaire.item.option.value[x]` is mapped to FHIR R4 element `Questionnaire.item.answerOption.value[x]` as `Equivalent`. The target context `Questionnaire.item.answerOption.value[x]` is a choice-type element and cannot directly hold extensions. The context is moved up to parent element `Questionnaire.item.answerOption`. The data type of the value must agree with the item.type.

If the user doesn't change the value, then this initial value will be persisted when the QuestionnaireResponse is initially created. Note that default values can influence results.

    v: Element `Questionnaire.item.item` is mapped to FHIR R4 element `Questionnaire.item.item` as `Equivalent`. There is no specified limit to the depth of nesting. However, Questionnaire authors are encouraged to consider the impact on the user and user interface of overly deep nesting.

The target context `Questionnaire.item.enableWhen.answer[x]` is a choice-type element and cannot directly hold extensions. The context is moved up to parent element `Questionnaire.item.enableWhen`. Multiple answers are treated as "or". E.g. Enable if question 1 = A, C or E. Components not specified in the answer do not need to match. For example, if enableWhen specifies code + system for a Coding, it is ok if the answer has a "display" element. I.e. treat the answer as a 'pattern'. The dataType of this element must be the same as the data type of the question being referenced.
