    v: When a resource has no narrative, only systems that fully understand the data can display the resource to a human safely. Including a human readable representation in the resource makes for a much more robust eco-system and cheaper handling of resources by intermediary systems. Some ecosystems restrict distribution of resources to only those systems that do fully understand the resources, and as a consequence implementers may believe that the narrative is superfluous. However experience shows that such eco-systems often open up to new participants over time.

comment:
  v: 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. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.

comment:
  v: 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).

short:
  v: Text summary of the resource, for human interpretation
definition:
  v: A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.
comment:
  v: 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 information is added later.

definition:
  v: Indicates the terminology server(s) that are known to be capable of returning and potentially expanding the value set(s) associated with the resource or a particular portion of the resource (depending on where the extension appears). If a full URL is not provided AND the requested query is a terminology operation (e.g. $lookup or $expand) the client SHOULD execute the operation against (one of) the preferredTerminologyServer(s) rather than the local repository. Systems SHOULD evaluate value sets using terminology servers as follows: First, try any terminology servers declared on the element in question. If there are more then one, try them in the order they appear. Then try any servers that appear on ancestor elements in order of closest ancestor up to any on the resource root If there are no declared servers or none of the ones listed provide a useful response, the form filler may then try any of the typical servers it would normally use. A 'useful response' means a response that provides a valid (though potentially empty) expansion. Clients MAY wish to log/report errors returned by terminology servers.

Allows commentary to be captured during the process of answering a questionnaire (if not already supported by the form design) as well as after the form is completed. Comments are not part of the "data" of the form. If a form prompts for a comment, this should be captured in an answer, not in this element. Formal assessments of the QuestionnaireResponse would use [Observation].

  v: Questionnaire is modular
definition:
  v: If present, indicates that this questionnaire has expectations with respect to assembly. Specifically, indicates whether this form requires assembly (i.e. it can't be used directly without invoking the [$assemble](OperationDefinition-Questionnaire-assemble.html) operation operation on it) and/or whether it is intended for use only as a 'child' in an assembly process. The assembly processs might mean filling in item metadata based on information looked up from item.definitions and/or retrieving sub-questionnaires pointed to by [sub-questionnaire](StructureDefinition-sdc-questionnaire-subQuestionnaire.html) extensions.
comment:
  v: SDC-conformant Questionnaires **SHALL** declare this extension if they require an assembly process prior to use. If not declared, then the Questionnaire is not necessarily safe for use as a child form and does not require assembly prior to use.

comment:
  v: The prior-edit functionality can be accomplished by adding questions to the screen as each subsequent question is answered (resulting in all questions being displayed in a single screen) or with a view that shows only one question at a time but allows backward navigation to view and/or edit prior answers.

definition:

comment:
  v: Indicates that the form has been designed with an expectation that it will be submitted to the specified URI. If multiple endpoints are specified, expectation is that answers are submitted to all endpoints. If no end-point is specified, then the form is not exclusively designed to be submitted to a specific site. If and where the form needs to be submitted or how the form should be internally processed must be inferred from external context or system business rules. Endpoints may have expectations around authorization, etc. Some of this may be learned by consulting the CapabilityStatement associated with the endpoint.

If a full URL is not provided AND the requested query is a terminology operation (e.g. $lookup or $expand) the client SHOULD execute the operation against (one of) the preferredTerminologyServer(s) rather than the local repository. Systems SHOULD evaluate value sets using terminology servers as follows: First, try any terminology servers declared on the element in question. If there are more then one, try them in the order they appear. Then try any servers that appear on ancestor elements in order of closest ancestor up to any on the resource root If there are no declared servers or none of the ones listed provide a useful response, the form filler may then try any of the typical servers it would normally use. A 'useful response' means a response that provides a valid (though potentially empty) expansion. Clients MAY wish to log/report errors returned by terminology servers.

Comments are not part of the "data" of the form. If a form prompts for a comment, this should be captured in an answer, not in this element. Formal assessments of the QuestionnaireResponse would use [Observation].

short:
  v: Can suppress from display to user
definition:
  v: This extension is used when defining high-level questionnaires that will then be used as a basis for 'derived' Questionnaires that are further refined for use in specific organizations or contexts. If the extension is present and set to 'true', it means that this item should be considered to be 'optional' from an adaptation perspective and that the question can be removed (i.e. not displayed) in derived questionnaires without impacting the validity of the instrument. Alternatively, the element can be marked as 'hidden' and 'readOnly' and have a value or descendant item values declared using initialValue or initialExpression. If the element with 'optionalDisplay=true' is marked as 'required=true', then this second approach is the only means to exclude the element from display.
comment:
  v: If a group or question that contains other groups or questions is marked as "optional", all of its contents are automatically also treated as optional.

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: 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: For questionnaires, see additional guidance and examples in the [SDC implementation guide](http://hl7.org/fhir/uv/sdc/2025Jan/behavior.html#maxDecimalPlaces). This specifies the maximum number of digits that can appear after the decimal point in a number. It counts all the digits to the right of the decimal point when the number is written out in full, standard decimal form (without 'e' or 'E'). For example, a number in scientific notation like 1.23e-4 equals 0.000123 when expanded; it would be consistent with a maximum number of decimal places of 6 or more.

comment:
  v: Provide either unitOption(s) or unitValueSet. If either of the extensions are present, the units for a Quantity element are constrained to only the units listed by the extensions - i.e. it is treated as a "required", not an "extensible" binding. In the absence of either, any unit is valid. See additional guidance and examples in the [SDC implementation guide](http://hl7.org/fhir/uv/sdc/2025Jan/behavior.html#unitOption). If this extension present and an answer is provided for the question item in the QuestionnaireResponse, then the valueQuantity **SHALL** have a Quantity.code and Quantity.system that match the Coding.code and system of one of the allowed values if the Coding has a code and/or system. If the Coding only has a display, then the Quantity.unit must match. (Note that Coding with only a display is strongly discouraged.) If there is a match on code and system, but no match on display/unit, systems MAY raise a warning. However, because of translation and bandwidth considerations, some systems **MAY** opt to drop the unit or express it in an alternate language.

comment:
  v: The results of the expression must correspond to the item type of the question the element appears on or must correspond to a resource, backbone element or complex data type for a group item. Resources are considered a match for the Reference item type. Quantity can be a match for decimal and integer items so long as a questionnaire-unit extension is present. If the expression returns coded data, it **SHALL* return the information as either code or Coding, not CodeableConcept. If the expression returns elements of type 'code', when the user selects one or more candidates, the code will be matched against the allowed Codings (from answerValueSet, answerOptions, or answerExpresssion). In this case, it is an error if there is more than one Coding with the same code.

definition:
  v: For items of type reference, the reference can be populated either by picking an existing entity or by creating a new one. In the latter case, this Questionnaire allows specifying the Questionnaire to use in creating the target instance. Typically this will result in a QuestionnaireResponse that can be [extracted](extraction.html) to produce the desired resource. However, if the target resource for the reference is a QuestionnaireResponse, then the QuestionnaireResponse resulting from the Questionnaire can be referenced directly.

definition:
  v: An expression that returns a boolean value for whether to enable the item.
comment:
  v: This is only permitted when the containing item does NOT have any enableWhen elements. If the expression involves comparisons between elements that have different precisions but are otherwise equal, FHIRPath will resolve the expression to an empty set, which will in turn evaluate to false (meaning the item won't be enabled). If this is not the desired behavior, the author should add a `.allTrue()` to the end of the expression, which will result in an indeterminate outcome because of precision differences being handled as 'true' and the item being enabled. Questionnaires SHOULD be designed to take into account challenges around varying precision to minimize non-deterministic situations by setting constraints around expected precision, etc. If the expression evaluates to something other than a boolean true or false, the Form Filler SHOULD still display the form, and if it does so, SHOULD treat the element as 'enabled' and display a warning to the user that the questionnaire logic was faulty and it's possible that the item shouldn't be enabled.

definition:
  v: May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
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.
requirements:
  v: Modifier extensions allow for extensions that *cannot* be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the [definition of modifier extensions](http://hl7.org/fhir/R4/extensibility.html#modifierExtension).

definition:
  v: This element is a URI that refers to an [ElementDefinition](http://hl7.org/fhir/R4/elementdefinition.html) that provides information about this item, including information that might otherwise be included in the instance of the Questionnaire resource. A detailed description of the construction of the URI is shown in Comments, below. If this element is present then the following element values MAY be derived from the Element Definition if the corresponding elements of this Questionnaire resource instance have no value: * code (ElementDefinition.code) * type (ElementDefinition.type) * required (ElementDefinition.min) * repeats (ElementDefinition.max) * maxLength (ElementDefinition.maxLength) * answerValueSet (ElementDefinition.binding) * options (ElementDefinition.binding).
comment:
  v: The uri refers to an ElementDefinition in a [StructureDefinition](http://hl7.org/fhir/R4/structuredefinition.html#) and always starts with the [canonical URL](http://hl7.org/fhir/R4/references.html#canonical) for the target resource. When referring to a StructureDefinition, a fragment identifier is used to specify the element definition by its id [Element.id](http://hl7.org/fhir/R4/element-definitions.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.
requirements:
  v: A common pattern is to define a set of data elements and then build multiple questionnaires for different circumstances to gather the data. This element provides traceability to the common definition and allows the content for the question to come from the underlying definition.

comment:
  v: 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.
requirements:
  v: Separating the label from the question text allows improved rendering. Also, instructions will often refer to specific prefixes, so there's a need for the questionnaire design to have control over what labels are used.

Group item instructions should be included as a display type item within the group. This is optional only to support form assembly situations where the text may be generated from another source. In an assembled Questionnaire, it should always be present.

definition:

comment:
  v: 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. When an item is disabled, all of its descendants are disabled, regardless of what their own enableWhen logic might evaluate to.
requirements:
  v: Allows questionnaires to adapt based on answers to other questions. E.g. If physical gender is specified as a male, no need to capture pregnancy history. Also allows conditional display of instructions or groups of questions.

  v: Extensions that cannot be ignored even if unrecognized
definition:
  v: May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
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.
requirements:
  v: Modifier extensions allow for extensions that *cannot* be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the [definition of modifier extensions](http://hl7.org/fhir/R4/extensibility.html#modifierExtension).

  v: The linkId for the question whose answer (or lack of answer) governs whether this item is enabled.
comment:
  v: If multiple question occurrences are present for the same question (same linkId), then this refers to the nearest question occurrence reachable by tracing first the "ancestor" axis and then the "preceding" axis and then the "following" axis.
