• interfaces that conform to ISO 10303-22 and to an ISO 10303 application protocol based on the previous edition of this document, also conform to a revision of that application protocol based on this edition of this document;
• the mapping tables of ISO 10303 application protocols based on the previous edition of this document remain valid in a revision of that application protocol based on this edition of this document.
