I don't know what you mean by ``strange.'' Is there a problem, or not?
Will a TKEY-aware client have trouble if I forward it a copy of a TKEY
record that someone else spontaneously sent me?

If so, the TKEY extension is broken. You said that TKEY servers could
spontaneously send TKEY records. Forwarding the records---treating them
as zone data---is indisputably correct behavior for my cache. See RFC
1123 section 6.1.3.5. See also http://cr.yp.to/djbdns/newtypes.html.

If, on the other hand, there is no problem, then why did you claim that
my AXFR client shouldn't forward the records?
