Crucial use of Yahoo XML sitemaps
 

Is it a fact that Yahoo XML sitemaps are dissimilar from XML Google sitemaps? Do you know of the disparity amidst these 2 dissimilar types of sitemaps? On this certain site that Google obviously preferred, I acquired an XML sitemap on. However, it stated XML parsing error and Yahoo was giving back some output. I am not really aware of what to consider if there is any kind of error integrated in this instance even though it was somewhat an uncomplicated file. Is Bing has the alike sitemap? Can anyone assist me here?
