I convert Xml file to other Xml file by Xslt (Xml Parser 5.0).
How to create xsi:type attribute, where xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance".

For example, I need to generate the next Xml document:

<Root ...
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:Alex="MyNameSpace"
...>
  <Form>
    <Control xsi:type="Alex:Treeview" .../>
    ...
  </Form>
</Root>
