Hi Michael!

Thanks for your explanation! Please allow me one more question.

I have now the following schema definition:
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified" targetNamespace="http://www.xyz.com" xmlns="http://www.xyz.com" xmlns:x="http://www.xyz.com">

The xmlns:x namespace is only used for the xs:unique. When I create an example xml from the schema with XML Spy all the created elements have the namespace prefix x attached. 

<x:root xsi:schemaLocation="http://www.xyz.com mg_ns.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:x="http://www.xyz.com">

Can I avoid this? I just want to use the default namespace in my xml file!
