Import Localization in B2C Commerce
Across all B2C Commerce import feeds, B2C Commerce processes xml:lang
attributes for all localizable elements the same way.
The xml:lang attribute must specify a locale that is present on an instance
including the default local. Though the locale can be configured as active or inactive. If the
xml:lang attribute specifies a locale that doesn’t exist on the instance,
the element isn't imported. B2C Commerce logs a data error to the import log.
