Re: OPT == type 41?

[Paul A Vixie <vixie@mibh.net>]

note that bind8.2.2, the first implementation which even knows the OPT RTYPE,
no longer treats (rtype<128) specially in any way.  unless there are known
defects in other (or older) implementations that would cause a meta-RR having
a type less than 128 to be a problem, i think we should just leave this alone.

/* Some kind of meta-RR? (not a QTYPE, but also not an RTYPE) */
