[TYPO3-dev] References to locallang.php files in core - needed anymore?

[Andreas Kiessling]

Hi,

i have to override some core labels and wanted to use the the 
locallangXMLOverride feature. But this did not work when i tried to 
change the page title:

$GLOBALS['TYPO3_CONF_VARS']['SYS']['locallangXMLOverride']['EXT:lang/locallang_tca.xml'][] 
= 'PATH_TO_MY_XML';

I had to use
$GLOBALS['TYPO3_CONF_VARS']['SYS']['locallangXMLOverride']['EXT:lang/locallang_tca.php'][] 
= 'PATH_TO_MY_XML';
since the labels e.g. in t3lib/stddb/tables.php refer to the php file:
'label' => 'LLL:EXT:lang/locallang_tca.php:title',

Is this some kind of backwards compatibility thing? Otherwise i will 
file a bug report, since i cannot remember having seen any locallang.php 
files for a loooong time ;)

Regards,
Andreas
