Hi
I'm affraid that's impossible but you can have a computed property ( which concats the first name and last name and returns the full name) and you can ignore it using XmlIgnore attribute.

        <br />
[XmlAttribute("firstname")]<br />
[System.ComponentModel.DefaultValue("----")]<br />
public string Firstname<br />
{<br />
  get<br />
  {<br />
    return ( "----" );<br />

  set<br />
  { <br />
     this.Firstname = value;<br />
  }<br />

  get {return new Class[0];} // ignore serialising for now<br />
  set {<br />
    foreach( Class newClass in (Class[])value) {<br />

      this.ClassList.Add(newClass);   // Johnson now knows that he/she is instructing Hydrodynamics 101 <br />

I know it's not complete, but hopefully it will illustrate my dilemma. <br />
