RFC 1873                Access Type Content-ID             December 1995


2. The Content-ID Access Type

2.1 Registration Information

       MIME access-type name:   content-id

       Required parameters:     none

       Optional parameters:     none

       Published specification: this document

       Additional requirements:

       The content-id header of the access-type=content-id MIME
       entity must match (be identical to) exactly one content-id
       in the same message, excluding other access-type=content-id
       entities.  Thus, the content-id access type can only occur
       within a multipart message and can refer to another body
       part anywhere in the same message.

       A MIME User Agent (MUA) constructs the resultant MIME body
       part as described below.  We call the access-type=content-id
       MIME entity the referring body part and the MIME body part
       to which it refers, the one with the matching content-id,
       the referenced body part.  The MIME entity that results from
       content-id access type consists of:

   (a) the referenced body part's content-type header,

   (b) the referring body part's headers except its content-type
       header,

   (c) any headers in the referenced body part not in the referring
       one,

   (d)  the line separating the headers from the body, and

   (e)  the referenced body part's body.
