I need to generate XML files from XSD generated Java Classes.

Some of the fields in those Java Classes as `Object` instead of any concrete type, and thus warrant a `xsi:type` attribute in the generated XML file, which is fine.

What is NOT fine though is that along with that `xsi:type`, the full namespace definition is added (`xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"`), and makes the XML very unreadable.

To sum it up, here is what I generate now:

```
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns:RootTag xmlns:ns="https://example.com">
    <ns:SomeObjectField xsi:type="xs:boolean" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">true</ns:SomeObjectField>
    <ns:SomeOtherObjectField xsi:type="xs:string" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">Some other value</ns:SomePtherObjectField>
</ns:RootTag>

```

And this is what I would like to generate:

```
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns:RootTag xmlns:ns="https://example.com" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <ns:SomeObjectField xsi:type="xs:boolean">true</ns:SomeObjectField>
    <ns:SomeOtherObjectField xsi:type="xs:string">Some other value</ns:SomePtherObjectField>
</ns:RootTag>

```
