[TYPO3-l10nmgr] Translation handling.

[Daise Antony]

Hi,
I have two website language german and austrian german, for pages/contents
its works fine at the front end and backend, but for extension i donot know
how to handle this

for example:
<languageKey index="de" type="array">
<label index="label">Vis kun kategori:</label>
</languageKey>

<languageKey index="de_AT" type="array">
<label index="label">Vis kun kategori:</label>
</languageKey>

Is this correct but its not working. any other solution to handle this .
Please reply.

Regards
Daise
