On the basis of the text in the thread, I have put the following
definitions into the current working version of the text (in section
1.2):

     Starting from a given IPv4 address (possibly the result of a
     query for an A RR), the term "existing reverse data" means that a
     query for <reversed-ip4-address>.in-addr.arpa. type PTR results
     in a positive response (i.e. one that provides a PTR RRset for
     the queried name in the answer section).

     Starting from a given IPv6 address (possibly the result of a
     query for an AAAA RR), the term "existing reverse data" means
     that a query for <reversed-ip6-address>.ip6.arpa. type PTR
     results in a positive response (i.e. one that provides a PTR
     RRset for the queried name in the answer section).

     The term "missing reverse data" means that the query for existing
     reverse data results in a negative response (i.e., one that does
     not provide a PTR RRset for the queried name in the answer
     section, often with a non 0 response code).

Please let me know as soon as possible if there are objections.

Best,

A
