The <theme> element is used to define multiple sites or views to be displayed on the Themes page. If themes are used, the title, tools, layers, etc. will be changed to an alternate set defined in a site configuration XML file when the theme is selected. If the same-extent attribute is set to true, the new site will open at the same map extent as when called. This is useful for displaying an alternate view or data set of the same area.
