Is it posible to translate a url prefix?

I would use the following to check for each language and then output the translated permalink structure. For instance:

if(ICL_LANGUAGE_CODE==en){
//translate your english the_prefix here
}
if(ICL_LANGUAGE_CODE==de){
//translate your german the_prefix here
}

I’m not sure about this, but I would think that you should be able to use the icl_register_string() and icl_t() functions to register, and output the translated text inside the above if statements. You can find more info about those functions here: WPML Register Function
