Overview
An SDMX Value List is a managed list of classification codes which are represented by values (example £ or $).
Value Lists can be referenced directly by Data Structure Definitions, or indirectly through Concepts to explicitly define the closed set of values for enumerated Dimensions, Attributes or Measures.

Usage
SDMX Value Lists are lists of classification codes used principally for defining the set of allowed values for enumerated Components in Data Structure Definitions (DSDs) or Metadata Structure Definitions which describe Reference Metadata.
Each code is a separate Item so must have an ID and a Name, but can also have an optional Description. While Code IDs must be unique within a Codelist, the same Code ID may be safely used in other Codelists. For instance: The code '£' may be used in a CURRENCY Value list to represent 'Pound Sterling', but also appear in an CURRECNY_DENOMINATION Value List to represent 'GB Pound'.
