DNSSEC involves no certificates and no certificate authorities. You know

As is documented in the paper of David Clark;

   http://portal.acm.org/citation.cfm?doid=383034.383037
   These certificates are principal components of essentially all
   public key schemes, except those that are so small in scale that
   the users can communicate their public keys to each other one to
   one, in an ad hoc way that is mutually trustworthy.

certificates are principal components of DNSSEC, a large scale
public key scheme.

Not calling intermediate certificates between zones certificates
does not change the reality that DNSSEC involves certificates.

Though there seems to be some confusion that DNSSEC security were
end to end

It is.

See the paper above to see why DNSSEC is NOT end to end.

Of cource, you may argue against David Clark, but, do so with
reasons.

        In a general PKI you need a third party to validated the
        name to certificate mapping because there is not natual
        method to do this.

        With DNSSEC the naming authority is the introducing authority.
        This is where DNSSEC differs from a general PKI infrastucture.
        This is also what make DNSSEC a better as a PKI for domain names.
