IMHO, that still meets the criteria.  Can you explain why you think it
may not?

If a client queries a bind server now it gets back a TTL that is the
same as the original, sure...  but that's always possible anyway.

I'd be happy to add text that you think would help to allow this
behavior to be considered compliant.

I think the thing I didn't talk about that probably does need to be
discussed is the AA bit.  Bind with my localroot (isi) config turns it
into an authoritative mirror, and thus the AA bit can be set.  Is this a
good thing or a bad thing?
