PUT fails to validate outer object name in json

I found that if I perform a PUT to toaster I am able to define any content for the outer module name. That is I can do a PUT to:

http://localhost:8181/restconf/config/toaster:toaster

with this body:

{
"ANY_TEXT_YOU_WANT":

}

Essentially the ANY_TEXT_YOU_WANT is completely ignored by the parser. We should either validate it, or better yet, do NOT require it. That is I should be able to PUT to the above toaster URL just

{
darknessFactor:"4"
}

since I am already in the context of toaster based on the URL.

I do not know if the same problem exists with XML.
