There are none and there shouldn't have to be any.  If the paragraph
about is not enough find a different provider.  Your current provider
does not have enough clue.

That said one could rev RFC 2317 to add such a directive.  The dnsop
working group at the IETF would be the place to send a RFC 2317 bis
internet draft.  Working groups are open to anyone.  Just join the
mailing list and contribute.

If you want you could also contact the authors of RFC2317 saying
that you want to do this.  They may even have the old nroff versions
you could use as a starting point.  Paul Vixie current email address
is paul at redbarn.org.
