In the catalog scenario (and this has been tested with running metamail code), you get: 1) The ability to send some, or part of the entire set of content. 2) The ability to analyze the packing list so that the processor can determine which components are needed or not. 3) Somewhat similar to this is the ability to analyze the packing list for security holes, and prompt a user. 4) The ability to, without parsing *all* the content, determine what the minimal packaging set is. 5) URL aliasing so you don't have to rewrite the content (like HTML mail requires for CID references) in order to resolve references to packaged content. 6) Packaging *format* independence. The catalog will work in multipart/related, plain multipart, or even in an XML syntax. Logically, as you not, the catalog is independent of the packaging scheme. Practically, you need a catalog in order to really use a packaging scheme... in leiu of an explicit catalog, you create one implicitly through the references. As I said, this has been tested using metamail. A fair while ago I prototyped an system for packing and unpacking SGML documents into multipart/related mail.
