I have an XML file with no namespaces defined:

<data>
  <textItems>
     <add name="test" value="test value"/>
  </textItems>
</data>

I can map this to a class with:

[XmlRoot]
public class data
{
  [XmlArray("textItems", Form=XmlSchemaFor.Unqualified)]
  [XmlArrayItem("add", typeof(addItem), Form=XmlSchemaFor.Unqualified)]
  public addItem[] Items;
}

public class addItem
{
  [XmlAttribute] public string name;
  [XmlAttribute] public string value;
}

That is fine. I can read in the XML file, deserialize it with XmlSerializer
to a data object and access the Items. I can alter the Items array and write
the data object to the XML file by serializing it.

However, I find that the XmlSerializer writes the root element with
xmlns:xsd and xmlns:xsi attributes:

<data xmlns:xsd="stuff" xmlns:xsi="stuff">
 <!-- stuff -->
</data>

How do I prevent that? [XmlRoot] does not have a Form property.
