Public property keyElement : Tid read GetkeyElement write SetkeyElement;
 
Public property requirements : string read Getrequirements write Setrequirements;

Description of why this constraint is necessary or appropriate.

Public property requirementsElement : Tstring read GetrequirementsElement write SetrequirementsElement;
 
Public property severity : string read Getseverity write Setseverity;

Identifies the impact constraint violation has on the conformance of the instance.

Public property severityElement : TConstraintSeverity read GetseverityElement write SetseverityElement;
 
Public property human : string read Gethuman write Sethuman;

Text that can be used to describe the constraint in messages identifying that the constraint has been violated.

Public property humanElement : Tstring read GethumanElement write SethumanElement;
 
Public property expression : string read Getexpression write Setexpression;

A [FHIRPath](fhirpath.html) expression of constraint that can be executed to see if this constraint is met.

Public property expressionElement : Tstring read GetexpressionElement write SetexpressionElement;
 
Public property xpath : string read Getxpath write Setxpath;

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

Public property xpathElement : Tstring read GetxpathElement write SetxpathElement;
 
Public property source : string read Getsource write Setsource;

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