Media Types 'text/csv' and 'text/comma-separated-values'

Hi all, I noticed that the MIME registration tree has an entry for 'text/tab-separated-values' but for some reason doesn't have any registration for 'text/comma-separated-values' or 'text/csv. I have been reviewing some of the stuff out there and so far have seen the following being used: application/csv text/csv text/comma-separated-values text/x-csv I was wondering if there would be any value to formally register two of the CSV types being used from the text tree (text/csv and text/comma-separated-values). I put together a small draft which hasn't posted to the ID repository yet. A copy should be available here: http://www.shaftek.org/publications/drafts/mime-csv/draft-shafranovich-mime-... Yakov
