InDesign shoudl assign unique attributes automatically in the XML while exporting it for translation purposes to diffentiate the new and already translated content in the file.

When there is an update to an already translated file, and when we need to extract and resend the XML file which contains both the new content and the already translated content, the XML should contain unique attributes for the body content or must atleast have an option to tag the translated content with one specific attribute and the new content with a different one so that the translation team can identify the differences and just translate the new only.
