S. Turner: AUTHOR [+2]
The RevocationInfoChoices type defined in [CMS] provides a set of revocation status information alternatives, which allows revocation information to be conveyed as part of the SignedData, EnvelopedData, AuthenticatedData, and AuthEnvelopedData content types. The intent is to provide information sufficient to determine whether the certificates and attribute certificates carried elsewhere in the CMS- protected content have been revoked. There may be more revocation status information than necessary or there may be less revocation status information than necessary.

Additional Cryptographic Message Syntax (CMS) Revocation Information Choices
The Cryptographic Message Syntax (CMS) allows revocation information to be conveyed as part of the SignedData, EnvelopedData, AuthenticatedData, and AuthEnvelopedData content types. The preferred format for revocation information is the Certificate Revocation List (CRL), but an extension mechanism supports other revocation information formats. This document defines two additional revocation information formats for Online Certificate Status Protocol (OCSP) responses and Server-Based Certificate Validation Protocol (SCVP) requests and responses.
