NIST, Federal S/MIME V3 Client Profile (NIST Special Publication 800-49) (Nov. 2002) (full-text).

Overview
This profile was developed as guidance in the development and procurement of commercial-off-the-shelf (COTS) S/MIME-compliant products. It identifies requirements for a secure and interoperable S/MIME V3 client implementation. NIST also was developing tests and testing tools to determine the level of conformance of an S/MIME V3 client implementation with this profile.
