There are quite some issues about DMARC. Let me mention aggregate report format first, as this brings out a third thing which can be done in parallel, namely to publish http://dmarc.org/dmarc-xml/0.2. Various tweaks have been proposed, I think they're well summarized in http://bit.ly/dmarc-rpt-schema For a second issue, consider whether report generators should track policy changes during the day and, in case, send multiple reports with different PolicyPublished. Otherwise, PolicyPublished would be valid for only a part of the reported rows, presumably the last. Is that acceptable? Another case for sending multiple reports at once is on hitting size limits. Is better to increase sending frequency instead? How to negotiate sending frequency between report consumer's ri= and producer's conditions deserves some discussion. I'm sure there's a bunch of other issues, and we should start to collect them. >> I don't see anything about PSD DMARC being inherently on the critical >> path for DMARCbis.

A second document present a process, possibly demonstrating how the required characteristics are met. Scott's I-D already outlines the characteristics of Branded and Multi-organization PSDs, that the experimental processes are suited for. Best Ale --
