Accepts an attribute, ConstMap<string,mixed> values, which can contain the following fields: title, detail, extra. The field extra itself should be a KeyedTraversable which can contain exception, 'message', 'stack', and errors (which is a Traversable that should contain ConstMap values that have a field and code).

$values = Map{
    'title' => 'Foo',
    'detail' => 'Bar',
    'extra' => [
        'errors' => [
            Map{'field' => 'foobar', 'code' => 'REQUIRED'},
            Map{'field' => 'example', 'code' => 'REQUIRED'}
        ],
        'exception' => [
            'class' => 'RuntimeException',
            'message' => 'Hello World',
            'stack' => '…',
            'previous' => [
                'class' => 'RuntimeException',
