0. Expression

Definition

A expression that is evaluated in a specified context and returns a value. The context of use of the expression must specify the context in which the expression is evaluated, and how the result of the expression is used.

Short An expression that can be used to generate a value

Control 0..*
This element is affected by the following invariants: ele-1

Is Modifier false

Invariants ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
exp-1: An expression or a reference must be provided (expression.exists() or reference.exists())

Is Modifier false

Summary false

Invariants ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())

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

6. Expression.name

Definition

A short name assigned to the expression to allow for multiple reuse of the expression in the context where it is defined.

Short name should align with code.Short name assigned to expression for reuse

Control 0..1

Control 1..1

2. Expression.id

Definition

Short Unique id for inter-element referencing

Control 0..1

Type

string

Is Modifier false

XML Format In the XML format, this property is represented as an attribute.

Summary false

4. Expression.extension

Definition

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 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.

Short Additional content defined by implementations

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.

Control 0..*

Type

Extension

Is Modifier false

Summary false

Alternate Names extensions, user content

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

This element introduces a set of slices on Expression.extension. The slices areUnordered and Open, and can be differentiated using the following discriminators:
