[TYPO3-english] file structure XLIFF language files

[Muriel le Pair]

Hi,

The language files and localization in TYPO3 extensions used to be 
pretty straightforward and easy to maintain. But I don't understand how 
the new XLIFF files structure works.

I have read
http://docs.typo3.org/typo3cms/CoreApiReference/Internationalization/Translation/Index.html

If I understood it correct, each translation for a language needs to be 
included in a separate language file. What is the directory structure 
for this? So in other words how does TYPO3 know which file needs to be 
included?

So for instance the language file for the BE of the extension is 
included in the directory
ext/Resources/Private/Language/locallang_be.xlf

How, and where, do I include the files for German, Dutch etc?
