How to set up correctly RealUrl tt_news and language with TYPO3 on multi-language site

Multilanguage site with News need the right realUrl configuration to show speaking-urls in right language:

www.mydomain.com/news/this-is-my-first-news.html

www.mydomain.com/it/news/questa-e-la-mia-prima-news.html

www.mydomain.com/de/news/dies-ist-meine-erste-news.html

standard realurl configuration is

[...]
, 'news' => array(
	array(
		'GETvar' => 'tx_ttnews[tt_news]'
		, 'lookUpTable' => array(
			'table' => 'tt_news'
			, 'id_field' => 'uid'
			, 'alias_field' => 'title'
			, 'addWhereClause' => ' AND deleted != 1'
			, 'useUniqueCache' => 1
			, 'autoUpdate' => 1
			, 'useUniqueCache_conf' => array(
				'strtolower' => 1
				, 'spaceCharacter' => '-'
			)
		)
	)
[...]

Add 4 rows:

,'languageGetVar' => 'L'
,'languageExceptionUids' => ''
,'languageField' => 'sys_language_uid'
,'transOrigPointerField' => 'l18n_parent'

Here the configuration to select right language title to create right speaking urls:

[...]
, 'news' => array(
	array(
		'GETvar' => 'tx_ttnews[tt_news]'
		, 'lookUpTable' => array(
			'table' => 'tt_news'
			, 'id_field' => 'uid'
			, 'alias_field' => 'title'
			, 'addWhereClause' => ' AND deleted != 1'
			,'languageGetVar' => 'L'
			,'languageExceptionUids' => ''
			,'languageField' => 'sys_language_uid'
			,'transOrigPointerField' => 'l18n_parent'
			, 'useUniqueCache' => 1
			, 'autoUpdate' => 1
			, 'useUniqueCache_conf' => array(
				'strtolower' => 1
				, 'spaceCharacter' => '-'
			)
		)
	)
