The draft describes a yang model for provisioning NAPTR RRs (and queries) for ALTO servers in the DNS reverse tree. This draft does not alter the DNS protocol or defined use of NAPTR RRs for this purpose. That is defined in other RFCs. There is one misspelled word in section 5.3.1.3 (last paragraph): "sugested" should be "suggested". There may be other editorial nits but they are likely minor.
