Add xsi:type to XML element
===

I have generated classes from xsd using xsd.exe. But now i have a problem that i need to add `xsi:type` to some of the xml elements. So i need the xml to look like something like this:

    <Book>
      <Name xsi:type="xsd:string">Foo</Name>
      <Published xsi:type="xsd:string">05.12.1982</Published>
      <Author>Bar</Author>
    </Book>

I know there is something called `XmlInclude` but i cant find a way to use it in my case.
