The IESG has received a request from the smime WG (smime) to consider the following document:Speaking as a member of the IETF community I find the question confusing, considering that both documents were obsoleted (or just about to be obsoleted in case of RFC 3281). Shouldn't this be RFC 5280 and draft-ietf-pkix-3281update-04.txt?- 'Cryptographic Message Syntax (CMS) ' RFC 3852 as a Draft Standard No technical issues were raised during the first Last Call. However, the Last Call failed to highlight two normative references to standards track documents of lower maturity: RFCs 3280 and 3281.
This abbreviated Last Call is focused solely on whether downrefs to these Proposed Standards are appropriate in the context of RFC 3852.
