Extension: Max value set

Official URL: http://hl7.org/fhir/StructureDefinition/elementdefinition-maxValueSet Version: 5.1.0-cibuild
Standards status: Trial-use Maturity Level: 3 Computable Name: MaxValueSet

This acts as an overall ‘required’ binding for an element that already has a less restrictive binding. It is used when there is a desire to have a ‘small’ enumerable binding that meets most needs and where the overall value set that the codes must be drawn from is ‘infinite’. The the base less restrictive binding SHALL be a proper subset of the max binding valueset. In most cases, this extension is used where the base binding is ‘extensible’.
