$ref?

$ref should do an ajax call (with id of the schema?)

but actually :
function getDefinition(path) {
var parts = path.split('/');
var def = root;
for (var p in parts) {
if (p === "0")
continue;
def = def[parts[p]];

}
return def;
}

i dont understand well what that's doing !
how that's work ? sorry it is more a question than an "issue" perhaps, feel free to close it.
