I will point out that specifications don't have to say "MUST" in order to be normative. Whether the working group wants "MUST" for emphasis or not is a question the working group has to answer. But the text Tero quoted (repeating here for convenience): > For each Authentication Mechanism underlying DMARC, perform the > required check to determine if an Authenticated Identifier > (#authenticated-identifier) exists for the message if such check > has not already been performed. ...is absolutely normative.
