Hi Ole,
What you are seeing is expected behavior for XMLBeans. The
classes are
generated this way because of the schema design pattern you
are using.
In your Tree xsd you are using the russian doll pattern
while in your
flat file xsd you are using the salami slice pattern.
Here is some additional information on the patterns in case
you are interested.

design_patterns.html
In answer to your question:
Is there any possibility to configure XMLBeans to generate a
flat
class structure for a tree-structured xml schema?
Not AFAIK, however you may want to look into the venetian
blind
pattern as you can work 'Type' classes in a manner like you
are
seeking.
Hope this helps,
