6.4.11 Allowed-value sets

The messages defined in this part of the RDR standard make intensive use of allowed-value sets. The allowed-value sets, the allowed values and their definitions are also contained in the DDEX data dictionary available from http://kb.ddex.net .

The messages defined in this part of the RDR standard contain a mandatory AvsVersionId Cell in the header Record identifying the version number of the allowed-value sets used in the creation of the messages. The AvsVersionId value at publication is 6.

DDEX may update the list of allowed-value sets over time and this may therefore require the AvsVersionId number to be increased. When this happens, the new current AvsVersionId will be publicised on the DDEX knowledge base. Any such updated version of the allowed-value sets which is issued on a date after the publication date of this part of the RDR standard forms part of this part of the RDR standard.
