Returnering af xml fra webservice

bemærk det er nasty! men sådan:
using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Xml.Serialization;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
{
    public Service () {}

    [WebMethod]
    public CustomizedInt HelloWorld() {
        return new CustomizedInt(123);
    }
}

[XmlRoot("abc", Namespace="")]
public class CustomizedInt : IXmlSerializable
{
    private int i=100;
    public CustomizedInt() {}
    public CustomizedInt(int i) {this.i = i;}
    public void WriteXml(System.Xml.XmlWriter writer) {writer.WriteString(i.ToString());}
    public System.Xml.Schema.XmlSchema GetSchema(){return null;}
    public void ReadXml(System.Xml.XmlReader reader) { }
}
