This is an Operations Directorate review of draft-leiba-smime-type-registry-02 for its operational impact. Summary: This draft is ready for publication as a Proposed Standard RFC. This draft creates an IANA registry for the smime-type values used with the application/pkcs7-mime media type by S/MIME. The security considerations section says: This document is purely administrative, and presents no security issues. It has no operational impacts for the same reason. It has some benefit for manageability by providing a single place for management tools that interpret smime-type values to obtain a list of the valid values and associated RFCs. The "RFC Required" policy for management of this registry is appropriate. Thanks, --David ---------------------------------------------------- David L.
