The trouble with using JSON.parse() as a validator is that it's probably 
doing way too much work. PLV8 is cool, and I keep trying to get enough 
time to work on it more, but I don't think it's a substitute for a JSON 
type with a purpose built validator and some native operations. I think 
these efforts can continue in parallel.
