ServicedComponent and Xml Serialization

Dear Members,

I am encountering a problem with the below class file.  When I attept to serialize the class Money I get the exception

 Message "There was an error reflecting type Test.Money'." string
The inner most exception is
 _message "Cannot serialize object of type Test.Money'. Consider changing type of XmlText member 'Test.Money.Value' from System.Decimal to string or string array." string

When I removed the inheritance to ServicedComponent it works.  Any insight into this problem?

Class Code
********
using System;
using System.EnterpriseServices;

namespace Test
{

 /// <remarks/>
 [System.Xml.Serialization.XmlTypeAttribute(Namespace="http://abc.com")]
 public class Money : ServicedComponent
 {
  private string mcurrency;
  private decimal mValue;
  private bool mcurrencySpecified;

  [System.Xml.Serialization.XmlAttributeAttribute(DataType="token")]
  public string currency
  {
   get
   {
    if ((this.mcurrency == null))
    {
     return "";
    }
    else
    {
     return this.mcurrency;
    }
   }
   set
   {
    this.mcurrency = value;
    this.mcurrencySpecified = true;
   }
  }

  [System.Xml.Serialization.XmlTextAttribute()]
  public decimal Value
  {
   get
   {
    return this.mValue;
   }
   set
   {
    this.mValue = value;
   }
  }
       
  [System.Xml.Serialization.XmlIgnoreAttribute()]
  public bool currencySpecified
  {
   get
   {
    return this.mcurrencySpecified;
   }
   set
   {
    this.mcurrencySpecified = value;
   }
  }
 }
}


Client Code to Serialize
*********
Test.Money mny = new Test.Money();
mny.currency = "USD";
mny.Value = 232.22m;

System.IO.StringWriter sw = new System.IO.StringWriter(new System.Text.StringBuilder());
System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(mny.GetType());
serializer.Serialize(sw, mny);
