Czy można wywołać funkcję rozszerzenia Java z Xalan na Androida?

Question

docx4j używa Xalana do konwersji dokumentów docx do HTML i opiera się głównie na rozszerzeniach Xalan Java, aby wykonać pracę.

Ale rozszerzenia Xalan nie działają dla mnie na Androida (praca z 4.0.3). LogCat mówi:

Android zawiera własną kopię niektórych bibliotek XML Apache. Jeśli chcesz dodać własne wersje do swojej aplikacji, najlepiej jest przepakować je przy użyciu instructions here.
