Some reasons that I had in mind were: * There is no character set issues -- the encoder doesn't need to know which character encoding was used. The specification doesn't have to talk about character sets (which makes up a big chunk of the current spec.) * It can deal with diff's of files with different character sets, e.g. converting ISO-8859-1 files to UTF-8. Like the draft says now, the text/* approach is unable to deal with this. * Sometimes text/* parts are modified by gateways, and this is usually avoided by using an application/* type. So the spec doesn't have to talk about these concerns. However I support doing both media types. For some situations, text/patch is appropriate. /Simon
