Yangtools Mangling REST names

I have the following model

container CSEBase {
description "Resource at the root of the tree";
container CSEBaseAttributes {
description "all attributes of CSEBase are in this container";
uses commonAttributesGroup;
leaf cseID

{ type string; description "The globally unique CSE identifier."; mandatory true; }

I noticed that the container name "CSEBaseAttributes" was changed to "Attributes". I was trying a JSON PUT for quite some time and RESTconf API explorer showed the actual URI

{
"CSEBase": {
"Attributes":

{ "cseID": "CSE-Id-Reinaldo" }

}
}

Without a tool like RESTconf API explorer I would never know that this mangling happened and to what name it was changed exactly. I checked RESTconf draft and the name CSEBaseAttributes is allowed. Maybe having the name prefix as the module is the problem.
