Section A.4 says:
example.com. SPF ( "v=spf1 " "-include:ip4._spf.%{d} " "-include:ptr._spf.%{d} " "+all" ) ip4._spf.example.com. SPF "v=spf1 -ip4:192.0.2.0/24 +all" ptr._spf.example.com. SPF "v=spf1 -ptr +all"
It should say:
example.com. TXT ( "v=spf1 " "-include:ip4._spf.%{d} " "-include:ptr._spf.%{d} " "+all" ) ip4._spf.example.com. TXT "v=spf1 -ip4:192.0.2.0/24 +all" ptr._spf.example.com. TXT "v=spf1 -ptr +all"
Notes:
According to Section 14.1 and Appendix B, the use of DNS RR type SPF (99) has been removed from the protocol.
