Well that's all you really had to say. :)  I admit that I didn't catch
the NXDOMAIN bit when I looked at the dig output, I was focused on the
ANSWER and ADDITIONAL sections.

I'll leave it up to the protocol experts to answer your question, but my
followup question is, what bad thing are you seeing happen because of
this? From your original post it seems like some resolvers are not doing
what BIND 9.6.2-P1 is doing, namely chasing the CNAME to come up with an
answer to the A query. Is that your concern?

Doesn't matter, recursion is not available on the authoritative server
anyway.
