Conditionally restricts answer options based on FHIRPath expressions that evaluate other answers in the questionnaire. When the expression evaluates to true, the specified option is restricted (hidden or disabled).
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
Must have either extensions or value[x], not both
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Extensions are always sliced by (at least) url
Source of the definition for the extension code - a logical name or a URL.
The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.
Value of extension - must be one of a constrained set of the data types (see [Extensibility](http://hl7.org/fhir/R5/extensibility.html) for a list).
FHIRPath expression that determines when this option is restricted.
Additional content defined by implementations
May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and managable, 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.
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.
Natural language description of the condition
A brief, natural language description of the condition that effectively communicates the intended semantics.
Short name assigned to expression for reuse
A short name assigned to the expression to allow for multiple reuse of the expression in the context where it is defined.
text/cql | text/fhirpath | application/x-fhir-query | etc.
The media type of the language for the expression.
The cardinality of this element is optional to allow text only as part of the authoring process. However, in order to be executable, the expression element must be specified.
The media type of the expression language.
An expression in the specified language that returns a value.
If Expression.expression and Expression.reference are both present, the Expression.expression might just be a name pointing something within the referenced content.
A URI that defines where the expression is found.
If both a reference and an expression is found, the reference SHALL point to the same expression.
