Why deos a Datasets WriteXML method srite an xml that can not be validated

Hi

In C# 2008 I have made a typed dataset called ParametersDataSet.xsd
It has a table called Parameters the table has two fields: Temperatures and Voltages

When it writes the XML it looks like this:

<?xml version="1.0" standalone="yes"?>
<DocumentElement>
  <ParametersTable>
    <Temperatures>12,30</Temperatures>
    <Voltages>3,5</Voltages>
  </ParametersTable>
</DocumentElement>


The xsd that VS has generated looks like this:

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="parametersDataset" targetNamespace="http://tempuri.org/parametersDataset.xsd" xmlns:mstns="http://tempuri.org/parametersDataset.xsd" xmlns="http://tempuri.org/parametersDataset.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:msprop="urn:schemas-microsoft-com:xml-msprop" attributeFormDefault="qualified" elementFormDefault="qualified">

          <xs:complexType>
            <xs:sequence>
              <xs:element name="Temperatures" msprop:Generator_UserColumnName="Temperatures" msprop:Generator_ColumnPropNameInRow="Temperatures" msprop:Generator_ColumnVarNameInTable="columnTemperatures" msprop:Generator_ColumnPropNameInTable="TemperaturesColumn" type="xs:string" minOccurs="0" />
              <xs:element name="Voltages" msprop:Generator_UserColumnName="Voltages" msprop:Generator_ColumnPropNameInRow="Voltages" msprop:Generator_ColumnVarNameInTable="columnVoltages" msprop:Generator_ColumnPropNameInTable="VoltagesColumn" type="xs:string" minOccurs="0" />
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:choice>
    </xs:complexType>
  </xs:element>
</xs:schema>

The problem is that the xml has an elemnt called DocumentElement and the XSD requires it to be called parametersDataset

So the question is what is microsoft thinking about? I mean I have made the dataset in the ide so the xsd text is autogenerated. I have saved the xml file using the DataSet that is based on the xsd and they end up not matching and thus I can't validate the xml from other programs like xmlspy !!!  grrrr

As I need to be able to edit the xml in xmlspy I need the xml to be validatable. It is not.
I have tried to change the DocumentElement  field in the xml to parametersDataset
Then I can't use the method: myTable.ReadXml("C:\\myXml.xml"); It fails
I have also tried to edit the xsd and change from parametersDataset to DocumentElement  
That also gives me an error when I try to read in the xml again

Is there a work around? Have I misunderstood something?

Thanks in advance

var myTable = new parametersDataset.ParametersTableDataTable();
  myTable.AddParametersTableRow("12,30", "3,5");
  myTable.WriteXml("C:\\myXml.xml");
