Multilingual Sitemap with some non-matching URLs

[Alex.Weintraub]

The website has two languages, English (.com/en-int/) and French (.com/fr-fr/).

Some pages only exist in French, and some only in English, but there are many that are a 1-to-1 match. So, my questions is, in the multilingual sitemap, should I only include the URLs that are alternates, and then create a 2nd sitemap for all non-matching URLs?

Or should I have 3 sitemaps: 1) Multilingual sitemap for all matching URLs (https://support.google.com/webmasters/answer/26208650 , 2) English sitemap for only URLs not included in multilingual sitemap, 3) French sitemap for only URLs not included in multilingual sitemap. And then create a sitemap index file to link to all 3 sitemaps.

you should have 1 sitemap index and 2 sitemaps.. 1 for English and 1 for French, and the index that links to them both.

If a page has an equivalent, include the rel="alternate" meta data. If not, don't include any meta data (just do the generic ones = loc, freq, priority)

Thanks for your response Oleg. But if I separate matching URLs into different sitemaps, then doesn't that go against what Google recommends by including them in 1 multilingual sitemap?
