productid should be adintegrate_rt_xxx where xxx is the native language name in lower case, i.e. deutsch.

version should be the version of vB Ad Management the language file was translated for, NOT the version of the language file.

url is where the translation can be downloaded, NOT where vB Ad Management can be downloaded. Although it's probably a good idea to include that somewhere on the download page!

Please only distribute the language xml file, none of the others.
