====== Translator z XTTML do R2ML ======

Kod translatora znajduje się w pliku: {{:pl:miw:miw08_xtt_r2ml:xttml2r2ml.xml|xttml2r2ml.xml}}

Konwersji dokonywałem programem oxygene. Należy utworzyć sobie schemat konwertowania przy użyciu powyższego pliku.

Poniżej przedstawiam efekt działania translatora na przykładzie.
