Redundancy is usually bad. > 2. Why is redundancy acceptable, here? I have to agree with John Levine here - why can't this just be an added flag in the existiing header registry. The cost of that should be *far* lower than a new registry. In fact after experience with having additional purpose-specific media type registries (something we should never have allowed), I am *strongly* opposed to overlapping registries of any sort. (Right now I owe IANA a response about how in the blazes to address the current multiple registries for media types.) Ned
