MarkupSitemap is essentially an upgrade to MarkupSitemapXML by Pete. It adds multi-language support using the built-in LanguageSupportPageNames. Where multi-language pages are available, they are added to the sitemap by means of an alternate link in that page's <url>. Support for listing images in the sitemap on a page-by-page basis and using a sitemap stylesheet are also added.
I just installed this module as an upgrade to the Markup Sitemap XML module and I really like it, thank you!
Unfortunately, I found that adding the "license" field to a image using ImageExtra doesn't display the license despite using a valid URL: https://creativecommons.org/licenses/by-nc-nd/4.0/
