Hi Roni,
Thanks a lot for the review. Please find responses inline.

Comments:
The first two comments are about changes from RFC 3971, if they are
intentional it may be good to have a section on changes from RFC 3971
and list these specific changes with backward interoperability issues if
there are.
1. In section 4 second paragraph “SEND certificates MUST include the
IP Resources extension for IPv6 Address …” Section 6.3.1 of RFC
3971 says “Router Authorization Certificates are X.509v3
certificates, as defined in RFC 3280, and SHOULD contain at least
one instance of the X.509 extension for IP addresses, as defined
in RFC 3779.” So why is it a MUST here.
The csi wg explicitly made a decision to go with basing the SEND
certificate profile on RPKI certificates [draft-ietf-sidr-res-certs]
instead of coming up with a fresh profile based on RFC3971. This
discrepancy is a result of that decision. I am not sure if there are any
backward compatibility issues since the SEND spec did not specify the
procedures for validating certificates without a IP resources extension,
2. The same paragraph has “Certified IPv6 address space SHOULD be
expressed using either addressPrefix or addressesOrRange
elements.” . Section 6.3.1 in RFC 3971 says “The X.509 IP address
extension MUST contain at least one addressesOrRanges element” as
for the addressPrefix according to this section “The X.509 IP
address extension MAY contain additional IPv6 subnet prefixes,
expressed as either an addressPrefix or an addressRange.”
This is unintentional. I don't think the statement in question adds any
value and can be safely removed. Is this ok?
3. In section 7 there are TBA1, TBA2 and TBA3, who will assign values
for these IDs.
The IDs have been allocated by the pkix wg. I have replaced the TBA
values with the actual allocated values.
Nits:
1. Section 5 has “an end user could local SEND deployment “ it looks
like there is a missing word in this sentence
OK. Replaced with "an end user could perform local SEND deployment"
2. In section 5 expand ULA.
OK.
Thanks
Suresh
