JSON documentation

Is there a good tool for writing开发者_如何转开发 JSON specifications?

I'm looking to improve my internal team's documentation capabilities, and at the same time generation validators (which could be throw into CouchDB view).

For the specification - i think JSON.org has enough detail.

As for validation- you can't go past JSONLint.
