As you can’t use »product attributes« and have two additional »custom taxonomies« just use get_the_term_list() to achieve what you want. The basic usage would be to place below code where you want to show the additional output – take a look at the codex page for information about formatting options.
Code:
//Show list of post specific terms from taxonomy language
echo get_the_term_list( $post->ID, 'language', 'Language: ', ', ', '' );
//Show list of post specific terms from taxonomy location
echo get_the_term_list( $post->ID, 'location', 'Location: ', ', ', '' );
