Hi,

suppose I have this metamodel:

class Chair has a reference named "parts" of type "Part". Part is
superclass to classes Leg and Arm.

by default a model instance gets serialized to this:

<chair:Chair xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:chair="chair.de">
<parts xsi:type="chair:Arm"/>
<parts xsi:type="chair:Leg"/>
</chair:Chair>

What I would like is:

<Chair>
<Parts>
<Arm/>
<Leg/>
</Parts>
</Chair>

What is the way to go?

Best regards, thanks in advance,

FLO

Florian,

Please use the EMF newsgroup (eclipse.tools.emf) for future questions
about EMF. More comments below.

Best is to write a schema with substitution groups and follow the steps
outlined in http://ed-merks.blogspot.com/2007/12/winters-icy-grip.html
to avoid ending up with a horrible API.
