An errata document was published on 31 May 2021, which lists a couple of updates to these and the related updated XSDs were published on 11 June 2021. On 26 November 2021 an updated version of the XSD related to the pacs.004 used as a positive response to a Recall was published.
XML Schema Definitions (XSDs) related to the aforementioned are also made available. (Note: XSD files can be opened via a text editor (e.g. Microsoft Notepad) or XML Schema editor).
Disclaimer: XSDs are not developed for ‘production’ purposes, they are to instantiate the business rules and restrictions contained in the implementation guidelines in a formal interchange format, sometimes referred to as Technical Validation Subsets (TVSs). Production instantiations should refer to the default ISO 20022 namespaces.
