title: Type does not have a default constructor automapper
body: <p>I have a problem:</p>
  
  <pre><code>public class TDocumentation
  {
     public XmlElement Summary { get; set; }
  
     public XmlElement LongDescription { get; set; }
  
     public XmlAttribute[] AnyAttr { get; set; }
  }
  </code></pre>
  
  <p>...and:</p>
  
  <pre><code>public class ProxieTDocumentation
  {
      public XmlElement Summary { get; set; }
  
      ......
  }
  
  
  Mapper.CreateMap&lt;Proxies.TDocumentation, TDocumentation&gt;()
  </code></pre>
  
  <p>...throws:</p>
  
  <p>----> System.ArgumentException : Type "System.Xml.XmlElement" does not have a default     constructor automapper</p>
  
  <p>How I can make a mapping on another?</p>
