So it sounds like their database *will* support the additional RR values, it's just that they don't make it easy to use them. Until they get their standard interface fixed, it sounds like Microsoft (or a 3rd party) could provide an alternative interface that additionally stored the RRs in a

I make no assumption on the question of TXT versus other DNS RR's at all. I view this topic to be totally orthogonal to the DNS question and unrelated. I see having o=~ as difficult to remember, describe and use, irrespective of what the DNS record looks like otherwise. Tony Hansen
