That's mostly intentional, because as far as I know, there are no browsers that support it yet. Even if we were to have the validator recognize srcset at all at this point, it would be just in order to emit a warning message that basically says, "Don't use the srcset attribute, because it's not supported by browsers yet." --Mike -- Michael[tm] Smith http://people.w3.org/mikeReceived on Tuesday, 18 December 2012 08:33:27 UTC
