1.  Is a special-use domain per [RFC6761], and does not (and will
        never) exist in the GID.  In this document, we refer to this as
        ".internal" for discussion purposes only following conventions 
in
        [draft-wkumari-dnsop-internal].

I read the above text as telling me that .internal will never exist in 
the GID.

  2.  Is an unsigned delegation within the (GID's) DNS root, with NS
        records likely pointing eventually to something like 
127.0.53.53.
        In this document, we refer to this as ".zz" following convention
        in [draft-ietf-dnsop-private-use-tld].  We note that 
[draft-ietf-
        dnsop-alt-tld] also proposed a private namespace (".alt") that
        also fits into this category.

This seems to be saying that .zz is an unsigned delegation. Am I missing 
something obvious here?
