External Code Sets

ISO 20022 external code-set mechanism.

Definition

Some code lists change faster than the message schemas, so ISO 20022 externalises them as 'External…1Code' types (ExternalPurpose1Code, ExternalCategoryPurpose1Code, ExternalServiceLevel1Code, ExternalLocalInstrument1Code). They are distributed as a spreadsheet on iso20022.org, allowing new values to be added without reissuing the schemas.

Origin

Published on iso20022.org (External Code Sets) and maintained quarterly by the Registration Management Group under ISO TC 68/SC 9.

Example in context

Schema type: <xs:simpleType name="ExternalPurpose1Code"> whose values are supplied outside the XSD.
