6.4 Allowed Value Sets
All messages defined in this standard make intensive use of allowed value sets. These allowed value sets are shared between all DDEX standards and DDEX provides an XML Schema Definition file for all of these allowed values. These values are also contained in the DDEX Data Dictionary available from https://kb.ddex.net/reference-material/data-dictionaries.
The full namespace for the XML Schema document for the allowed value sets is:
DDEX may regularly extend this list of allowed-value sets. Any such extensions to this list are issued on a date later than the date on which this standard is issued form part of this standard. Thus the list of allowed value sets contains the list of allowed value sets valid on the data of issuance of this standard.
