Given rpc definition:

rpc some-action {
  input {
    anyxml data;
  }
}

And data passed into restconf:

{
  "input" : {
    "data" : [
      { "key" : "value" }
    ]
  }
}
 

results in following json element received from gson codec:

"data" : {
  "array-element" : { "key" : " value" }
}

This breaks how jsonrpc digests anyxml data from restconf.

I can't find reference to this behavior in RFC7951, so I think this is a bug.
