xsd.exe generate proper type

Question

"C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools\xsd.exe"

/order /n:eDD.KlasyXML /c /language:CS

to generate my C# code.

Woks pretty fine but my xsd files contains type definition for example:

  <!--==========================================================-->
  <!--===                    QuantityType                    ===-->
  <!--==========================================================-->
  <xs:simpleType name="QuantityType">
    <xs:annotation>
      <xs:documentation>
        <doc:description value="Quantity" />
      </xs:documentation>
    </xs:annotation>
    <xs:restriction base="xs:decimal">
      <xs:totalDigits value="15" />
      <xs:fractionDigits value="3" />
      <xs:minExclusive value="0" />
      <xs:pattern value="[1-9]\d{0,14}" />
      <xs:pattern value="([1-9]\d{0,13}|0)\.[0-9]" />
      <xs:pattern value="([1-9]\d{0,12}|0)\.\d[0-9]" />
      <xs:pattern value="([1-9]\d{0,11}|0)\.\d\d[0-9]" />
    </xs:restriction>
  </xs:simpleType>

Element definition looks like this:

<xs:element name="Quantity" type="emcs:QuantityType"/>

But output in XML looks like this:

<q4:Quantity>2000.0000</q4:Quantity>

Is there any way to force xsd.exe to respect type definition and output xml in proper format like this:

<q4:Quantity>2000.000</q4:Quantity>

This is how I convert object to string:

public static string XMLToString<T>(this T toSerialize)
{
    StreamReader streamReader = null;
    MemoryStream memoryStream = null;
    try
    {
        XmlSchemaSet schema = new XmlSchemaSet();
        schema.Add("eDD.SchematyXML", "traderToEdd.xsd");

        memoryStream = new MemoryStream();
        XmlWriterSettings xmlWriterSettings = new XmlWriterSettings();

        XmlWriter xmlWriter = XmlWriter.Create(memoryStream, xmlWriterSettings);
        XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
        xmlSerializer.Serialize(xmlWriter, toSerialize);
        memoryStream.Seek(0, SeekOrigin.Begin);
        streamReader = new StreamReader(memoryStream);
        return streamReader.ReadToEnd();
    }
    finally
    {
        if ((streamReader != null))
        {
            streamReader.Dispose();
        }
        if ((memoryStream != null))
        {
            memoryStream.Dispose();
        }
    }
}

How add schema or namespace to this?

I probably do something wrong but it don't work for me. I tried but whatever I done fails. The solution was to use xsd2code. It can generate Fraction Digits Attribute and much more. Its not free but it is worth any penny.
