var schema = {
  type: {
    $type: 'string',
    $set: ['success', 'error'],
    $default: 'success',
    $nullable: false
  },
  data: {
    $type: 'array',
    $nullable: false,
    $minLength: 0,
    $maxLength: 100,
    $item: {
      $type: 'object',
      $nullable: false,
      $value: {
        firstName: '1', // not nullable
        lastName: '', // nullable
        fullName: {
          $type: 'dynamic',
          $validator: function (opt) {
            return opt.value || opt.getValueByPath('./firstName') + ' ' + opt.getValueByPath('./lastName');
          }
        },
        title: {
          $type: 'string',

        grade: {
          $type: 'number',
          $set: [1, 2, 3],
          $nullable: true
