Definition: A value set is the set of values that is valid for use in a specific context, e.g. to define the domain of a data element. Value sets may be defined extensionally by listing the valid values explicitly, or intensionally by providing a definition by which valid values can be identified.



Reference Definition: A value set represents a uniquely identifiable set of valid concept representations (e.g., terms, codes), where any concept representation can be tested to determine whether or not it is a member of the value set. Value set complexity may range from a simple flat list of concept codes drawn from a single code system, to an unbounded hierarchical set of possibly post-coordinated expressions drawn from multiple code systems.
