So it should be clarified as such:
o Data for each Domain Owner's subdomain separately from mail from
the sender's Organizational Domain, even if there is no explicit
subdomain policy
Perhaps changed to something more like:
o A separate report should be generated for each 5322.From subdomain,
regardless
of which policy domain was used during receipt of messages
For the other thread with Ale, is there anything wrong with stating both
minOccurs/maxOccurs set at "1" so that it's more clear that it must be once,
and only once?
