[Json] Proposal to move forward on acceptable roots

["Joe Hildebrand (jhildebr)" <[e-mail]>]

One way we could go on the topic of what goes in the root that would work
for me would be for us to add a non-normative section to I-JSON giving
protocol design advice, and move the issue of potential incompatibility of
non-[object,array] roots to that section.

Into that section, we can also put some suggestions about how to encode
integers, floats, and dates in strings, how to do forward-compatibility
with objects (MUST ignore what you don't understand), and whatever other
pearls of wisdom we come up with.

Yes, I know that will make the document take longer, and open up other
areas for us to argue about.
