+<h1>Embedding media in a frame</h1>
+<p>The normal way to display embedded media is either in an object element, if your
+browser supports it, or on a page of its own. These methods are compliant with 
+XHTML strict standards. However, in some cases, your browser may not support the
+type of file you want to embed, and you still want it to appear within your site's context 
+(with the navigation breadcrumbs etc..). The only way to do this is to enable this option.
+However, this is not compliant with XHTML strict.</p>
+<p>
+If your users have the option screenreader switched on in their profile, it will override this
+option, so that frames will never be used to display embedded media for these users.
