title: One or more XML expansion packs are available for this file
body: <p><strong>UPDATED:</strong></p>
  
  <p>I have now added the following code based on the answers below:</p>
  
  <pre><code>foreach (Word.XMLSchemaReference reference in Globals.ThisDocument.Application.ActiveDocument.XMLSchemaReferences)
  {
      if (reference.NamespaceURI.Contains("ActionsPane"))
      {
          reference.Delete();
      }
  }
  </code></pre>
  
  <p>This gives me no errors at design, time, but still gives the user the message described in the original question about choosing an xml expansion pack.  So the original problem hasn't been solved.</p>
  
  <p><strong>ORIGINAL QUESTION:</strong></p>
  
  <p>Using Visual Studio 2013, I have created a Word Document level project which has an action pane.  Everything works well.  The only problem is what when someone uses this documents action pane to insert text into the document and then save it.  The next time that saved document is opened, the user gets the following message</p>
  
  <pre><code>One or more XML expansion packs are available for this file.
  Choose one from the list below.
  No XML expansion pack
  Microsoft Actions Pane 3
  </code></pre>
  
  <p>How do I stop this from happening when saved documents are opened?</p>
