Sorry, but I still don't get it!
I can create a node that is referencable by adding the mix:referenceable attribute. That much is clear.
How can I now create another node elsewhere in my tree that references this node? The documentation is not clear on this.
Thanks,
Paul.

Hi Paul,
every node, which is referenceable has a UUID. This ID is used for
references. The created value (by the ValueFactory) should be a String. This
String contains the UUID.
In my example the record node has a property "forge:reference". There you
can place the references.
<propertyDefinition name="forge:Reference" requiredType="Reference"
autoCreated="false" mandatory="false" onParentVersion="COPY"
protected="false" multiple="true"/>
My document node is referenceable. So it has an unique ID.
<supertype>mix:referenceable</supertype>
So take the node which should hold the refernce (in my example the record)
and take the node which you want to reference to and create a Reference
Value with the help of the ValueFactory.
This value has to be set for the "forge:Reference" property.
Enough?! :)
