Hi, Sean, Thanks for your reply. It makes sense to me.

RFC8017 obsoletes RFC 3447, which was what we referred to until after the original IETF LC. RFC 3447 was in the DOWNREF registry but was still called out in the original IETF LC for this draft. Note that since we’re referring to RSASSA-PKCS1-v1_5 which was in RFC 3447 and didn’t change in RFC8017 I’m hoping that this is a non-issue. spt
