XML Localization Interchange File Format (XLIFF) "is an XML-based format created to standardize localization. XLIFF was standardized by OASIS in 2002. Its current specification v1.1." It is aimed at the localization industry and specifies elements and attributes to aid in localization. (Wikipedia)
XLIFF "allows you to store extracted text and metadata in a common format that can be carried from one step to the next in the localization process and ultimately allows you to get the data back in their original format. XLIFF is maintained by the OASIS XLIFF Technical Committee." (Savourel 2007)
XLIFF is a format that can assist in computer assisted translation.
