DataSet Xml Schema validation does not work

Hi,

I am trying to validate the XML that I read into a DataSet using an XML schema (xsd). However, even though the xml file is invalid, I don't get any invalid xml exception. When I print the DataSet contents, it just skips the invalid entry, which is an element named "EmailAddress". In XML schema, the element name is "Email".

I tried setting EnforceConstraints field of the dataset before reading the XML. But I think it is not related with Schema. It does not change the behavior.

Here is my code:

Code:

---

using System;
using System.IO;
using System.Data;
using System.Xml;
using System.Xml.Schema;

namespace Trial
{
    public class Program
    {
        static public void Main(String[] args)
        {
            var myDs = new DataSet();

            myDs.ReadXmlSchema("../../AddressBook.xsd");
            myDs.ReadXml("../../AddressBook.xml");
            myDs.AcceptChanges();

            myDs.WriteXml(Console.Out);

            foreach (DataTable table in myDs.Tables)
            {
                Console.WriteLine("Table {0} ==>", table.TableName);
                foreach (DataColumn column in table.Columns)
                {
                    Console.WriteLine("Column {0}", column.ColumnName);
                }
            }
        }
    }
}

Here are my xml and xsd files

Code:

---

<?xml version="1.0"?>

<!-- 06-xml/05-schema -->

<AddressBook>

        <AddressBookEntry>

                <Name>

                        <First>Niel</First>
