Hi,

I am trying to generate a GMF Editor from a DTD. For this I converted
the DTD to an XSD using trang and then generated the ecore model.

One problem I have is that I want my nodes to have ports as side affixed
children. This can be done by adding a child reference that points to
the port element to the mapping of the node. However, the port is no
child of the node, because the node points (non-containment reference)
to another element which contains the ports, but it is not allowed to
add a child reference to a node which is not a real child of the node in
the ecore model. Is there another way to get my port elements to appear
next to the node elements in a diagram?

Regards,
Matthias
