DataSet Xml Schema validation does not work

Question

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);

                }

            }

        }

    }

}

[/code]

Here are my xml and xsd files

[code]
