We've been discussing entities, levaing NOTATION to the side for the moment. On NOTATION, I think we need to be careful -- Wherever possible, we should use MIME-types in harmony with the rest of the net -- whether we also want to support FPIs on the same optional basis as we should for documents is an open question. Their real use, it seems to me, would be for private types, and since we have the x- mime types (though their use is discouraged officially, I think) we may not even need them for that. For notation, I don't know that we need FPIs because that SYTEM ID (if a MIME type) is already globally-unique and persistent, with a well-defined naming authority: IANA. I think it would be a compatibility issue, more than anything. My impression is that public notations are not very common, but I could be wrong. -- David I am not a number.
