ShortOptional Extensions Element
Definition

Optional Extension Element - found in all resources.

Cardinality0..1
ConditionsThe cardinality or value of this element may be affected by these constraints: ele-1
Constraints
  • ele-1: All FHIR elements must have a @value or children
    hasValue() | (children().count() > id.count())
  • ext-1: Must have either extensions or value[x], not both
    extension.exists() != value.exists()
Mappings
  • rim: n/a
  • rim: N/A
Extension.id
Shortxml:id (or equivalent in JSON)
Definition

unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

ConditionsThe cardinality or value of this element may be affected by these constraints: ele-1

  • ele-1: All FHIR elements must have a @value or children
    hasValue() | (children().count() > id.count())
Mappings

Extension.extension
ShortAdditional Content defined by implementations
Definition

May be used to represent additional information that is not part of the basic definition of the element. In order 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Comments

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.

Comments

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.

Extension.extension:bgThreshold.value[x]:valueQuantity
ShortA measured or measurable amount
Definition

A measured amount (or an amount that can potentially be measured). Note that measured amounts include amounts that are not precisely quantified, including amounts involving arbitrary units and floating currencies.

Cardinality0..1
TypeQuantity
Comments

The context of use may frequently define what kind of quantity this is and therefore what kind of units can be used. The context of use may also restrict the values for the comparator.

ConditionsThe cardinality or value of this element may be affected by these constraints: ele-1
Constraints
  • ele-1: All FHIR elements must have a @value or children
    hasValue() | (children().count() > id.count())

    code.empty() or system.exists()
