Detailed Description

Class handles translation mode for an object.

Objects may not use any translations at all

use translations for title/description only or
use translation for (the page editing) content, too.

Currently supported by container objects and ILIAS learning modules.

Content master lang vs. default language

If no translation mode for the content is active no master lang will be set and no record in table obj_content_master_lng will be saved. For the title/descriptions the default will be marked by field lang_default in table object_translation.
If translation for content is activated a master language must be set (since concent may already exist the language of this content is defined through setting the master language (in obj_content_master_lng). Modules that use this mode will not get informed about this, so they can not internally assign existing content to the master lang
