The WriteXml method of System.Data.DataTable generates a XML with a faulty type
description in the schema section for ushort column if XmlWriteMode.WriteSchema
parameter is specified: usignedShort instead of unsignedShort 

Test program:

//gmcs -t:exe -r:System,System.Data Program.cs

using System;
using System.Text;
using System.Data;

namespace ConsoleApplication2
    class Program
        static void Main(string[] args)
            DataTable table = new DataTable("TableWithUnsignedShortColumn");
            table.Columns.Add("shortColumn", typeof(ushort));


            System.IO.TextWriter writer = new System.IO.StringWriter();
            table.WriteXml(writer, XmlWriteMode.WriteSchema);


Output sample with Microsoft CLR:

<xs:element name="shortColumn" type="xs:unsignedShort" minOccurs="0" />

Output sample with Mono

<xs:element name="shortColumn" type="xs:usignedShort" minOccurs="0" />
