ElementDefinitionConstraint Captures constraints on each element within the resource, profile, or extension.
id Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
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.
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).
key
Allows identification of which elements have their cardinalities
impacted by the constraint. Will not be referenced for constraints that
do not affect cardinality.
keyElement
Extensions for key
requirements
Description of why this constraint is necessary or
appropriate.
requirementsElement
Extensions for requirements
severity
Identifies the impact constraint violation has on the
conformance of the instance.
severityElement
Extensions for severity
human
Text that can be used to describe the constraint in messages
identifying that the constraint has been violated.
humanElement
Extensions for human
expression
A FHIRPath expression of constraint that
can be executed to see if this constraint is met.
expressionElement
Extensions for expression
xpath
An XPath expression of constraint that can be executed to see if
this constraint is met.
xpathElement
Extensions for xpath
source
A reference to the original source of the constraint, for
traceability purposes.
