Right, because the UA/AT is in a much better place to know how to help the user in these cases. The idea here is to help the user. We can get better accessibility by letting user agents compete on best handling of these images than we can by letting servers, who have near zero motivation to address this issue, try to come up with some half-baked solution. > Henri S. has classified this as possibly being "faked" content, without > stopping to think if there is a way to minimize the amount of faked or > spurious alternative text being generated; I continue to advocate > reserved values in lieu of any other suggestion, but curiously await > feedback from the afore-mentioned W3C working groups. Reserved values are just syntactic variants on omitting the attribute. There is no practical difference. (Well, other than reserved values being significantly less usable in today's UAs, and omitting the alt="" attribute being cleaner, which is why the spec says to omit the attribute instead of inventing some new reserved value.) -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
