I have one quick comment/question on draft-krecicki-dprive-dnsenc-01.

In Section 3.1 it states:

   APPLICABLE NS NAME          a <domain-name> of NSes that use this
                               key.  This allows for different NSes for
                               a zone to use different keysets (eg. when
                               the secondary is operated by different
                               entity than primary).  This field might
                               contain wildcard symbol '*' at any place
                               (including as a part of a single label -
                               eg. 'ns*.foo*bar.example.com'), which
                               matches zero or more characters and can
                               cross label boundaries ('ns*.example.com'
                               matches 'ns.example.com',
                               'ns1.example.com' and
                               'ns1.foobar.example.com'), single '*'
                               means any.

So the semantics of '*' is different from that of RFC1035/4592.  Is
this deviation really necessary?  It's not immediately clear to me
from the draft about the definite need for it, and I suspect this can
be easily a nightmare for implementers.  Also, calling this a
<domain-name> might also not be very appropriate as it handles '*' in
a different way.
