To be clear, I'm not objecting to this choice.  I'm merely noting that use
of TXT has been a point of controversy in other discussions at the IETF.
Some groups have decided to proceed with TXT, some have preferred to use
different or new RRTYPEs, and some have not yet decided.  I would like the
working group to consider this question soon so it doesn't delay consensus
later.
