title: Where definitions in public.xml are linking to?
body: <p>Let me explain with example... Consider 'android.R.layout.simple_list_item_multiple_choice'. It used to create multi-select lists. But the only definitions I found:</p>
  
  <p>/platform/frameworks/base/core/res/res/values/public.xml:</p>
  
  <pre><code>&lt;public type="layout" name="simple_list_item_multiple_choice" id="0x01090010" /&gt;
  </code></pre>
  
  <p>/platform/frameworks/base/api/current.xml:</p>
  
  <pre><code>&lt;field name="simple_list_item_multiple_choice"
   type="int"
   transient="false"
   volatile="false"
   value="17367056"
   static="true"
   final="true"
   deprecated="not deprecated"
   visibility="public"
  &gt;
  </code></pre>
  
  <p>But where is actual layout defined? When multi-select list created I see checkbox, where it comes from?</p>
