ElementDefinition.Constraint

Captures constraints on each element within the resource, profile, or extension. If the element is present, it must have a value for at least one of the defined elements, an @id referenced from the Narrative, or extensions

Captures constraints on each element within the resource, profile, or

extension.

If the element is present, it must have a value for at least one of the

defined elements, an @id referenced from the Narrative, or extensions

param id_

None

param extension

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.

param modifierExtension

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).

param key

Allows identification of which elements have their cardinalities impacted by

the constraint. Will not be referenced for constraints that do not affect cardinality.

param requirements

Description of why this constraint is necessary or appropriate.

param severity

Identifies the impact constraint violation has on the conformance of the

instance.
param human

Text that can be used to describe the constraint in messages identifying that

the constraint has been violated.
param expression

A [FHIRPath](fhirpath.html) expression of constraint that can be executed to

see if this constraint is met.
param xpath

An XPath expression of constraint that can be executed to see if this

constraint is met.
param source

A reference to the original source of the constraint, for traceability

purposes.
