Hi,
one more remark from me: The syntax with "lang:sr" is only used on destination tags - all name tags have only the language code, but not the "lang" keyword, e.g.  alt_name:sr-Latn

If an object has two alternative names, they can be added with one tag, e.g. 

alt_name:lang:sr = Шел Адашевци аутопут
alt_name_1:lang:sr = Шел аутопут

->

alt_name:sr = Шел Адашевци аутопут; Шел аутопут
