>This document specifies the syntax and semantics for the
>Cryptographic Message Syntax (CMS) content constraints extension.
>This extension is used to determine whether a public key is
>appropriate to use in the processing of a protected content.  In
>particular, the CMS content constraints extension is one part of the
>authorization decision; it is used when validating a digital
>signature on a CMS SignedData content or validating a message
>authentication code (MAC) on a CMS AuthenticatedData content or CMS
>AuthEnvelopedData content.  The signed or authenticated content type
>is identified by an ASN.1 object identifier, and this extension
>indicates the content types that the public key is authorized to
>validate.  If the authorization check is successful, the CMS content
>constraints extension also provides default values for absent
>attributes.  [STANDARDS TRACK]
>
>This is now a Proposed Standard Protocol.

>STANDARDS TRACK: This document specifies an Internet standards track
>protocol for the Internet community,and requests discussion and suggestions
>for improvements.  Please refer to the current edition of the Internet
>Official Protocol Standards (STD 1) for the standardization state and
