There was a discussion of this last year: http://lists.w3.org/Archives/Public/www-style/2009May/0212.html I think it boiled down to whether to use names from the Unicode database or not and if so, how specific the names should be. I think the idea of named ranges for the 'unicode-range' descriptor is interesting. I don't like the idea of additional descriptors for this (e.g. script-coverage, etc.). It would help to have a clearer idea of the use case you imagine for this to be able to judge whether named ranges are better than simple ranges. One other use I can imagine is for easily dividing up large CJK fonts into defined character ranges. Ex: unicode-range: jis-level-1, jis-level-2; /* alias for the set of codepoints in the JIS Level 1 and 2 ranges */ JIS Level 1 characters occur more commonly than JIS Level 2, etc., so this would be a convenient way for font vendors to package fonts so that fonts containing infrequently used characters were only downloaded in fallback situations. No matter what the set of aliases, I think we can only practically reference ranges that are defined clearly and have a standard reference point such as the Unicode database. Cheers, John Daggett
