Official URL: `http://hl7.org/fhir/StructureDefinition/valueset-unclosed`				Version: 5.0.0-snapshot3
draft as of 2020-12-28				Computable Name: VS Unclosed
Flags: Non-Modifier				OID: 2.16.840.1.113883.4.642.5.1209

Context of Use: Use on Element ID ValueSet.expansion

Definition

Marks that the expansion is incomplete, and values other than those listed may be valid. This may be used because post-coordinated codes are allowed, and no practical expansion can be produced.

Comment:

This extension exists to allow for definition and use of value sets that are unbounded by definition, including those for which it may always be impractical to set bounds. This extension is not used to communicate value sets that are limited for practical reasons. The offset and total elements of the expansion support that use case.
