-------------------------------------------------------------
[~noble.paul] - looks good! It'll be really cool when this type of flattening
is available for XML too. One thing, I think the "echo" debugging parameter in
there should at least be "json.echo" to qualify it, though with XML flattening
future, maybe "echo" is just fine, or "flatten.echo"? I'm just thinking out
loud with namespacing in mind.
