[TYPO3-mvc] Additional parameters in ExtensionManagementUtility::getFileFieldTCAConfig()

[Jan Kornblum]

Dear newsgroup,

i am using 
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getFileFieldTCAConfig() 
like this:

ExtensionManagementUtility::getFileFieldTCAConfig(
   'images',
   array(
	   'minitems' => 0,
	   'maxitems' => 3,
	   // START - Additional parameters
	   'foreign_match_fields' => array(
		   'fieldname' => 'images',
		   'tablenames' => 'tx_myext_domain_model_test',
		   'table_local' => 'sys_file',
	   ),
	   // END - Additional parameters
   ),
   $GLOBALS['TYPO3_CONF_VARS']['GFX']['imagefile_ext']
)

...to be able to create a FAL FileReference in a controller context 
like explained in this example:

http://www.typo3tiger.de/blog/post/extbase-fal-filereference-im-controller-erzeugen.html

This works fine, but i'm not sure if this is the right way  and if this 
might be compatible with future versions of TYPO3 / Extbase, as the 
default getFileFieldTCAConfig() configuration (and, for example 
tt_content's field "image") is missing my examples parameters 
('foreign_match_fields').

Does anybody know a little more about this?

Kind regards, Jan
