Object References with XML
The following example shows an association structure in which the destination object has already been defined and therefore needs to be referenced.
Example
<Class2 oim:id="_2">
...
</Class2>
<Class1 oim:id="_1">
<Class1OriginAssocEnd>
<Class2 oim:href="#_2"/>
...
</Class1OriginAssocEnd>
</Class1>
