It sounds like the intended meaning of rel(alternate) is:

1. Don't ever download this resource from the network. Only pull it from the cache, if possible.
2. If it was located, invert the normal "last wins" relationship of @font-face rules, and just always use this. (Or maybe only do that for unicode-range? I'm not sure.)

I'm not really sure how this would work, or how to rigorously explain it, but it sounds like what you might want is to have a cache() function for src that only pulls from the cache, and then just put this @font-face last. If the srcs succeed, it'll win over all the partial fonts you specified earlier; if they fail, it'll automatically fall back to the partial fonts.

How do you expect things to make it into the cache if you're never actually loading them? Is it intended that this actually expresses a "low-priority" download semantic, or are you just relying on the fact that users might have already downloaded the given font from some other, less responsible webpage?
