Use this option when you have a master XML Index file that lists each individual country/language files and you want us to download from the web. Your XML site map folder should look like the sample below. It is a master file with a list of all of the individual files.
1. The URL's in the XML must be to XML site maps and not individual URL's.
2. File format must be xml
3. Each country must have a unique country/language XML file entry in the index file.
