title: Is there any Android XML documentation?
body: <p>Is there any sort of xml reference?</p>
  
  <p>I found this which turned out to be invaluable for me</p>
  
  <ul>
  <li><a href="http://groups.google.com/group/android-developers/msg/d334017d72909c79" rel="noreferrer">(Multiple) Shape drawing with XML</a></li>
  </ul>
  
  <p>But I can't figure out how I was supposed to know how to do that, had
  I not found that post.</p>
  
  <p>I know that the api reference has xml attributes listed for many of
  the classes... but what about xml tags? Where is it documented that I
  could build a shape using <code>&lt;padding&gt;</code>, <code>&lt;corners&gt;</code>, <code>&lt;solid&gt;</code> tags?</p>
  
  <p>I'd really like to know where I can find such documentation. </p>
