Folks,

While this ticket/enhancement specifically mentions ARC, I could perhaps see the usefulness in other places.  It seems like it would be more beneficial to create a method by which other documents could provide XML- based "extensions" to the report.  This would allow mechanisms relying on DMARC to independently define their reporting schema to be included in DMARC aggregate reports.  Alternately, we could focus specifically on ARC, and work to include that in the base XML.  This means that any later reporting requirements could again require changes to the core drafts.

If possible, we'd like to see if we can reach some consensus within a few weeks.
