[TYPO3-mvc] How should/can I pass parameters to an object's constructor using dependency injection?

[Simon Tuck]

Hi,
I'm looking at the changes in the latest version of extbase (1.3) and I 
was wondering how I would/could pass parameters to an object's 
constructor using the DI container.

So, in the following example taken from the current changelog 
(extbase/ChangeLog.txt):

class Tx_Foo_Controller_MyController
{
	protected $loggingService;

	/**
	 * @param Tx_Foo_Service_LoggingService $loggingService
	 */
	public function injectLoggingService(Tx_Foo_Service_LoggingService 
$loggingService)
	{
		$this->loggingService = $loggingService;
	}
}

How can I pass parameters to the constructor of the logging service 
singleton?:

class Tx_Foo_Service_LoggingService implements t3lib_Singleton
{
	/**
	 *
	 * @param string $foo
	 * @return void
	 */
	public function __construct($foo)
	{
		$this->setFoo($foo);
	}
}

Thanks!
Simon
