As I wrote
Bosnian with extension hr-BA is a language they speak Croats in Bosnia. Still call it Bosnian Croatian.
Bosnian with extension bs-Latn-BA is a language they speak mostly Muslims. Still call it Bošnjački.
Bosnian with extension sr-Latn-BA is a language they speak Serbs in Bosnia. Still call it Bosnian Serbs.
and Bosnian with extension sr-Cyrl-BA is a language they speak Serbs in Bosnia Cyrillic writing. Still call it Bosnian Serbs too.
All are official languages and are called Bosnia. (Bosanski).
My suggestion is to leave two language for Bosnia bs-Latn-BA and bs-Cyrl-BA.(Name:"Bosanski latinica" i Name:*"Bosanski čirilica")
I got it. But both installation.hr-BA.xml and installation.bs-Latn-BA.xml files have the same "Name" attribute of the "Language" element. It means that when a store owner opens dropdownlist on the installation page, he'll see two absolutely the same elements ("Bosanski"). Could you please rename them so we can distinguish between them. One of them will be "Bosanski latinica", the other one "Bosanski čirilica" (I can do it myself, but not 100% sure that it'll be correct). This is what I meant.
And I'm a bit confused with http://www.mushroomslook.com/Installation/installation.hr-BA.xml and http://www.mushroomslook.com/Installation/installation.hr-HR.xml files. They're absolutely the same (except language name) according to WinMerge. Should they be the same? If yes, I'm sure only one language will be enough.
