I like schemas for validation and strong types. I also like self-describing systems when all goes to hell and I'm debugging either my own protocols or someone else's.

I have this crazy idea that there's a middle ground: self-describing and schemas?

We can kind of glue this together (there's lots of json schemas floating around out there now, it seems), but it would be awfully interesting to see these well-supported as a pair (with explicitly language agnostic schema definitions -- which seems to be a sticking point for most of the json schema strapons).
