Добавить существующий узел элемента к узлу над ним, используя XSLT

Question

У меня есть следующее XML содержимое файла, которое я преобразую, используя lxml и XSLT.

contents.xml

Моя проблема в том, что когда я запускаю следующее преобразование, он не добавляет узел penalty внутри block над ним.

То, что я получаю:

Я довольноновичок в XSLT, как мне этого добиться?
