\n Sitemap extensions are a great way to tell Google about the different kinds of content and
\n their metadata that you’re using on your site. Often the content on your pages may fit into
\n multiple kinds of extensions; for example, you might be publishing news articles that embed
\n images and videos. Additionally, your pages may be localized as well, which might mean that
\n you could add hreflang<\/code> annotations for your localized pages.\n<\/p>\n

Namespaces<\/h2>\n

\n For each sitemap extension that you want to use in a sitemap you need to specify the
\n respective namespace that declares the tags the extension supports. This is done with the
\n xmlns<\/code> attribute of the urlset<\/code> tag. The namespaces for the sitemap
\n extensions Google supports are:\n<\/p>\n\n\n\n\n\n\n
Extension tags and their namespace definitions<\/th>\n<\/tr>\n
image:<\/code><\/td>\n\n http:\/\/www.google.com\/schemas\/sitemap-image\/1.1<\/code><\/a>\n <\/td>\n<\/tr>\n
news:<\/code><\/td>\n\n http:\/\/www.google.com\/schemas\/sitemap-news\/0.9<\/code><\/a>\n <\/td>\n<\/tr>\n
video:<\/code><\/td>\n\n http:\/\/www.google.com\/schemas\/sitemap-video\/1.1<\/code><\/a>\n <\/td>\n<\/tr>\n
xhtml:<\/code> (for hreflang<\/code>)<\/td>\n\n http:\/\/www.w3.org\/1999\/xhtml<\/code><\/a>\n <\/td>\n<\/tr>\n<\/table>\n

Declaring multiple namespaces<\/h3>\n

\n To declare multiple namespaces, add the respective namespace references to your sitemap as
\n described in the documentation of the respective extensions. Here’s an example that shows how
\n to add the news, video, and xhtml (for hreflang<\/code>) extensions to a sitemap:\n<\/p>\n

<\/div>\n

Combining sitemap extensions<\/h2>\n

\n Once you declared the namespaces, follow the implementation details from the respective sitemap
\n extension documentation you’re going to use.\n<\/p>\n
