Allows disabling certain questionnaire options for the containing item based on evaluating expressions.
ofType(ElementDefinition).binding.where(strength='required').exists() or where(%resource.is(Questionnaire)).exists(answerValueSet.exists() or answerOption.exists())
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
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.
Indicates one or more options that should be disabled if the specified expression evaluates to true
Options listed are expected to correspond to either answerOption values or Codings found in the answerValueset expansion. Systems SHOULD treat non-matching answerOptions and MAY treat non-matching answerValueset Codings as an error.
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).
The expression to evaluate. If the evaluation results in true, then the specified options will be suppressed.
