title: How to generate an MST file for a WiX instance transform?
body: <p>I have an installer built using WiX, using the InstanceTransforms tag. For example:</p>
  
  <pre><code>&lt;InstanceTransforms Property="INSTANCEID"&gt;
     &lt;Instance Id="Install2" ProductCode="*" UpgradeCode="guid-goes-here" ProductName="Product" /&gt;
  &lt;/InstanceTransforms&gt;
  </code></pre>
  
  <p>I'd like to view the effects of the instance transform using Orca.</p>
  
  <p>I imagine I need to generate an mst file to do this.</p>
  
  <p>What steps do I need to take to get from my WiX source file to an mst file representing my instance transform?</p>
