title: Serializing int type without quotes
body: <p>I have the following class to be serializing:</p>
  
  <pre><code>[Serializable]
  public class LabelRectangle { 
    [XmlAttribute]
    public int X { get; set; }
    [XmlAttribute]
    public int Y { get; set; }
    [XmlAttribute]
    public int Width { get; set; }
    [XmlAttribute]
    public int Height { get; set; }
  }
  </code></pre>
  
  <p>and it is going to be serialized and looks like this</p>
  
  <pre><code>&lt;LabelRectangle X="15" Y="70" Width="10" Height="1" /&gt;
  </code></pre>
  
  <p>but I would like to get the following result:</p>
  
  <pre><code>&lt;LabelRectangle X=15 Y=70 Width=10 Height=1 /&gt;
  </code></pre>
  
  <p>that is serializing int type values without quotes. Is it possible and how if yes?</p>
