[news.eclipse.modeling.m2m] question to modelmodification with ATL

[musich@xxxxxx (musich)]

I'm trying do a Modelmodification with ATL, but I do not know how can I 
insert a new instance of input model element to output model.
Can Anyone help me?

for example:
my metamodel is the following:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore";>
 <ecore:EPackage name="Author">
   <eClassifiers xsi:type="ecore:EClass" name="Author">
     <eStructuralFeatures xsi:type="ecore:EAttribute" name="name" 
ordered="false" unique="false" lowerBound="1" eType="/1/String"/>
     <eStructuralFeatures xsi:type="ecore:EAttribute" name="surname" 
ordered="false" unique="false" lowerBound="1" eType="/1/String"/>
   </eClassifiers>
 </ecore:EPackage>
 <ecore:EPackage name="PrimitiveTypes">
   <eClassifiers xsi:type="ecore:EDataType" name="String"/>
 </ecore:EPackage>
</xmi:XMI>

my inputmodel:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0"
   xmlns:xmi="http://www.omg.org/XMI"; xmlns="Author">
 <Author name="David" surname="Touzet"/>
 <Author name="tobias" surname="zimmerman"/>
</xmi:XMI>


how can I get this outputmodel ?

<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0"
   xmlns:xmi="http://www.omg.org/XMI"; xmlns="Author">
 <Author name="David" surname="Touzet"/>
 <Author name="Tobias" surname="zimmerman"/>
  <Author name="Tomas" surname="Hering"/>
</xmi:XMI>
