Localization API
The Localization API provides the building blocks TYPO3 uses to resolve locales and translate labels from XLIFF files in both Backend and Frontend code. It covers locale parsing and normalization, creation of context-aware translation services, and convenient helpers for TypoScript, Extbase and Fluid.
