Not an issue, more of a question:
So for example this would be a simple string instead of TaxableAmount.
[GeneratedCodeAttribute("XmlSchemaClassGenerator", "2.1.1181.0")]
[SerializableAttribute()]
[XmlTypeAttribute("TaxableAmount", Namespace="")]
[DebuggerStepThroughAttribute()]
[DesignerCategoryAttribute("code")]
public partial class TaxableAmount
{
/// <summary>
/// <para xml:lang="en">Gets or sets the text value.</para>
/// </summary>
[XmlTextAttribute()]
public string Value { get; set; }
}
