Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. This element is labelled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation. QuestionnaireResponse.language (language) is equivalent to QuestionnaireResponse.language Element `QuestionnaireResponse.language` is mapped to FHIR R4B element `QuestionnaireResponse.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.

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).

The mappings for `QuestionnaireResponse.questionnaire` do not cover the following types: Reference. The mappings for `QuestionnaireResponse.questionnaire` do not cover the following types based on type expansion: display, identifier, reference. If a QuestionnaireResponse references a Questionnaire, then the QuestionnaireResponse structure must be consistent with the Questionnaire (i.e. questions must be organized into the same groups, nested questions must still be nested, etc.). QuestionnaireResponse.status (status) is equivalent to QuestionnaireResponse.status Element `QuestionnaireResponse.status` is mapped to FHIR R4B element `QuestionnaireResponse.status` as `Equivalent`.

QuestionnaireResponse.authored (authored) is equivalent to QuestionnaireResponse.authored Element `QuestionnaireResponse.authored` is mapped to FHIR R4B element `QuestionnaireResponse.authored` as `Equivalent`. May be different from the lastUpdateTime of the resource itself, because that reflects when the data was known to the server, not when the data was captured.

However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. This element is labelled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation.
Element `QuestionnaireResponse.language` is mapped to FHIR R4B element `QuestionnaireResponse.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.
