{
            "test": {
                "prototype": "spec/button/button-test[Test]",
                "properties": {
                    "button": {"@": "button"}
                }
            },

            "button": {
                "prototype": "montage/ui/button.reel",
                "properties": {
                    "element": {"#": "button"}
                }
            }
        }
