Usage
SDMX Codelists are lists of classification codes principally used for defining the set of allowed values for enumerated components in Data Structure Definitions or Metadata Structure Definitions.
Each code is treated as a separated Item so must have an ID and a Name, but can also have an optional Description. While Code IDs are unique within a Codelist, the same Code ID may be safely used in other Codelists. For instance: The code 'A' may be used in a Frequency Codelist to represent 'Annual', but also appear in an Industry Codelist to represent 'Agriculture'.
By convention, Codelist IDs are given a 'CL_' prefix to distinguish them from other structures. For instance: CL_FREQ, CL_REF_AREA, CL_AGE.
