That's far from impossible, the way we do it the compiled schema can optionally 
be stored with the encoded data. I've been recommending that for storage one 
should use that method (since data outlives applications) but for ephemereal 
transmissions it shouldn't be needed.

I also have ideas about how to store it once for multiple files.
