I get to see following codes used at the beginning of  sitemap.xml for different sites ? What's the differences between these three set of codes ? Can you clarify this ?

<?xml version="1.0" encoding="UTF-8" ?>
<urlset xmlns="">
<?xml version="1.0" encoding="utf-8" ?>
<urlset xmlns="">
<?xml version="1.0" encoding="UTF-8" ?>
<urlset xmlns="" xmlns:xsi="" xsi:schemaLocation="">

    Different versions of the same file to validate the sitemap against
