Google: Single sitemap for multiple content type

Google has always been changing structure of site maps for better accessibility for crawlers since 2005 when it was first launched. Previously you had to create specialized sitemaps for different content type.

Now Google has changed its sitemap structure for multiple content type (images, video etc). Now you need to create a single site map which will cater for different content like video sitemap. images, mobile URLs, geo information or code. The structure for single sitemap is also similar to the standard sitemap, with an extra node referencing different content types. Google webmaster will depict the same change in the dashboard.
