title: styles multiple inheritance
body: <p>Is there any way to make a style inherit from multiple other styles, instead of just being limited to:</p>
  
  <pre><code>&lt;style name="WidgetTextBase"&gt;
      &lt;item name="android:typeface"&gt;serif&lt;/item&gt;
      &lt;item name="android:textSize"&gt;12dip&lt;/item&gt;
      &lt;item name="android:gravity"&gt;center&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="BOSText" parent="WidgetTextBase"&gt;
      &lt;item name="android:textColor"&gt;#051C43&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>I would like BOSText to also inherit from:</p>
  
  <pre><code>&lt;style name="WidgetTextHeader"&gt;
      &lt;item name="android:textStyle"&gt;bold&lt;/item&gt;
  &lt;style&gt;
  </code></pre>
