Deprecation: #107938 - Deprecate unused XLIFF files 

See forge#107938

Description 

The following XLIFF files have been deprecated, as they are not used in TYPO3 Core anymore:

  • EXT:backend/Resources/Private/Language/locallang_view_help.xlf
  • EXT:backend/Resources/Private/Language/locallang_sitesettings_module.xlf
  • EXT:backend/Resources/Private/Language/locallang_siteconfiguration_module.xlf
  • EXT:backend/Resources/Private/Language/locallang_mod.xlf
  • EXT:belog/Resources/Private/Language/locallang_mod.xlf
  • EXT:beuser/Resources/Private/Language/locallang_mod.xlf
  • EXT:core/Resources/Private/Language/locallang_mod_usertools.xlf
  • EXT:core/Resources/Private/Language/locallang_mod_system.xlf
  • EXT:core/Resources/Private/Language/locallang_mod_site.xlf

  • EXT:dashboard/Resources/Private/Language/locallang_mod.xlf
  • EXT:extensionmanager/Resources/Private/Language/locallang_mod.xlf
  • EXT:form/Resources/Private/Language/locallang_module.xlf

  • EXT:install/Resources/Private/Language/BackendModule.xlf
  • EXT:info/Resources/Private/Language/locallang_mod_web_info.xlf
  • EXT:linkvalidator/Resources/Private/Language/Module/locallang_mod.xlf
  • EXT:recycler/Resources/Private/Language/locallang_mod.xlf

They will be removed with TYPO3 v15.0.

The console command vendor/bin/typo3 language:domain:list does not list deprecated language domains, unless the option --deprecated is used.

Impact 

Using a label reference from one of these files triggers a E_USER_DEPRECATED error.

Affected installations 

Third party extensions and site packages that use labels from the listed sources will not be able to display the affected labels with TYPO3 v15.0.

Migration 

If the desired string is contained in another language domain, consider to use that domain. Otherwise, move the required labels into your extension or site package.
