The "required" property is not supported ?

When using this Basic example schema on : http://json-schema.org/examples.html

{
    "title": "Example Schema",
    "type": "object",
    "properties": {
        "firstName": {
            "type": "string"
        },
        "lastName": {
            "type": "string"
        },
        "age": {
            "description": "Age in years",
            "type": "integer",
            "minimum": 0
        }
    },
    "required": ["firstName", "lastName"]
}

The software generates this error:

2015-06-16 21:19:15.1404 [Error] Could not parse the schema: file:///c:/temp/jschema.json
