Hall" <ehall@xxxxxxxxx> Message-ID: <411CDF3E.7000507@xxxxxxxxx> | Others should note that RFC2048 is designed to facilitate registrations -- | more definitions for common data-types are widely preferred over a | proliferation of "x-foo" media-types that result from high registration | barriers (read the intro to 2048 if you don't believe me) -- and that's | the limited objective of this proposal. All that is fine, and not an issue with anyone. The problem is that for the tag to be meaningful, there must be at the very least a common understanding of what it means and how it can be processed. Better of course is an actual published specification of the content format (somewhere). Without that all you have is a label for a meaningless bucket of bits. When I send a message how do I know whether it is appropriate to use the new tag or not? What content qualifies, and what does not? Is it sufficient if I'm sending a file whose name is "mbox"? (Or which has an extension of ".mbox" or similar). Or is it necessary that the content contain mail in some form? If so, is it enough if I have a jpeg file showing a mail box containing letters? It is 100% useless to define a label without that referring to some well understood content. kre _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
