Merge (flatten) multiple XSDs into one automatically
<p>I have a more XSD files which contain the description of the message structure. 
Our application can use only one XSD so at the moment I need to merge the XSDs into one XSD manually. Take care with the namespaces and so one.</p>

<p>Do you have any idea how can I make it automatically without copy paste?</p>

<p>I have tried to generate classes from the XSDs and generate again a single XSD but that was not worked.</p>
