[news.eclipse.modeling.gmf] Problem with link

[serena.Amber.Young@xxxxxxxxx (Serena )]

Hello.

I use a XML Schema to generate the EMF model, and then generate a GMF 
Editior.
 I defined a Relation between tables in XML Schema like this:
 <xsd:complexType name="Relation">
 <xsd:sequence>
 <xsd:element  ecore:reference="Table"  name="source" type="Table"/>
 <xsd:element  ecore:reference="Table"  name="target" type="Table"/>
</xsd:sequence>
 </xsd:complexType>
    
 when I create a relation between "tablea" and "tableb"in Editor, the 
persistence format like this:
   <relation>
     <source>tablea</source>
     <target>tableb</target>
   </relation>
 I want to add some extra properties under <source> and <target>, it may 
like this:
  <relation>
      <source>
          <name>tablea</name>   
      </source>
      <target>
          <name>tableb</name>
          <many>true</many>
      </target>
 </relation>

How do I do that?

 Thanks
 Serena
