Dear Warren and Wes,

Thank you for your replies (and Wes, thank you for stopping by the RFC Editor 
desk at IETF 124!).  We have updated our files accordingly. We have an 
additional clarification and question.

1) Thanks for the clarifications regarding Tables 2 and 3.  The only changes we 
made were to Table 2 - we updated values 17, 23, 252, and 254 to reflect the 
mnemonic names.

2) We note that in the Normative References section, [DNSKEY-IANA] lists the 
direct registry name and [DS-IANA] lists the top registry name. Should  
[DS-IANA]  list the direct registry name for consistency?
