These implementation guidelines ( ) set out the Single Euro Payments Area ( ) rules for implementing the e-Mandate Service ISO 20022 XML message standards based on version 1.0 of the 2021 SEPA Direct Debit (SDD) Core Rulebook, which takes effect on 21 November 2021.
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.
