Hello everyone,
when re-reading this document I've realized one limitation which is not
explicitly mentioned:
---
3.2. Responders
... A name server MAY also include more than one ZONEVERSION option in
the response if it is authoritative for more than one zone of the
corresponding QNAME. A name server MUST NOT include more than one
ZONEVERSION option for a given TYPE and LABELCOUNT.
---
The current option cannot be used to represent version info for answer
like this:
QNAME:
qname.zone1.test. A
Answer:
qname.zone1.test. CNAME target.zone2.test.
target.zone2.test. A 192.0.2.1
When the responder is authoritative for both zones - zone1.test. and
zone2.test. - then there's no way to represent ZONEVERSION for zone2.test.
If this was discussed before I've missed it - sorry!
Is this worth solving or at least documenting?

P.S. I'm away for ~ one week, so I apologize for late responses.
