It seems like requireParams() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        $this->countEnabled = $val->isValid();

        if ($this->countEnabled) {
            if (!$this->countToken instanceof Mailcode_Parser_Statement_Tokenizer_Token_Variable) {
                $this->validationResult->makeError(
                    t('Invalid count type.' . ' ' . 'Expected Variable.'),
