title: What is the meaning of "vnd" in MIME types?
body: <p>Reading up on content providers, I keep wondering why both the category and type of Android MIME types are prefixed with vnd. For example:</p>
  
  <pre><code>vnd.android.cursor.dir/vnd.&lt;something&gt;
  vnd.android.cursor.item/vnd.&lt;something&gt;
  </code></pre>
  
  <p>Anyone know what this stands for and what the point is?</p>
