Thread:Support/Values on Special:AdvancedTranslate

I would like to retrieve values that can be accessed through Special:AdvancedTranslate in a more computer-friendly format and, if possible, on any MediaWiki wiki (not only on this wiki).

On FAQ it says that translations are saved in pages Special:PrefixIndex/MediaWiki:Sp-translate but for example I can't find messages for Slovene language (sl).

Is there any option to retrieve these translations in raw format (except to include MediaWiki source files or to parse export on Special:AdvancedTranslate)?
