XSLT: доступ к конфигурации xml в файле XSLT

Я пытаюсь напечатать названия фруктов, которых нет в data:fruit. В моем случае я ожидаю Pineapple, Kiwi. Я получаю доступ к data:fruit в конфигурации XSLT xml с помощью 'select = "document('')/*/data:fruit/attribute/@value"'. В настоящее время я получаю следующую ошибку.

Ошибка:

Error executing XSLT at line 24 : Exception thrown by URIResolver resolving `` against `'. Found while atomizing the first argument of fn:string-join()
