Hy, just a short question I can't find in the docs.
Where is the mapping between Ecore models and XML schema done?
How could I map attributes in Ecore on XML Elements in place of XML
Attributes?

Ralf,
Yes, to specialize the serialization and deserialization of instances
you either need to mark up the model to direct the code in
org.eclipse.emf.ecore.xmi to behave differently or you need to
specialize the code to behave differently, in general.
The generated XMI.xsd and all the generated .xsd files for that matter,
are not used for anything. They are generated for you to use directly
for whatever purpose requires a schema that *approximates *the grammar
for instances.

Ralf,
I assume you found this document:
http://dev.eclipse.org/viewcvs/indextools.cgi/%7Echeckout%7E /emf-home/docs/overviews/XMLSchemaToEcoreMapping.pdf
The same EAnnotations that are used when mapping XSD to Ecore (which is
done by org.eclipse.xsd.ecore.XSDEcoreBuilder in the org.eclipse.xsd
plugins) can be used to mark up any Ecore model to direct how its
instances will be serialized as XML (by the reflective
serialization/deserialization code in org.eclipse.emf.ecore.xmi).
