title: Allow Angular $sanitize to keep certain tags
body: <p>I want to enable the user in my app to use certain white-listed HTML tags (like <code>&lt;div&gt;&lt;/div&gt;</code> &amp; <code>&lt;span&gt;&lt;/span&gt;</code>) but disable other HTML tags like <code>&lt;script&gt;&lt;/script&gt;</code>, <code>&lt;input/&gt;</code>.</p>
  
  <p>I can create a custom directive in order to just do it manually, but I understood there's a way to do this using <code>$sanitize</code>, <code>$compileProvider</code> and the <code>$compileProvider.directive</code>. I can't find any documentations on this feature.</p>
  
  <p>How to disable all html besides <code>&lt;div&gt;</code> tags without any attributes, using <code>$compileProvider.directive</code> instead of my own directive?</p>
