One should be able to model composed links in the gmfmap file. Such a link can be composed out of  a center node and two links to to a source and target. For example Entity Relationship diagrams have such links consisting out of more than one element. The target is that the user can draw a link between two nodes a he usally does but will get 3 elements created (2 links 1 node in the middle). The topic is discussed in the forums http://www.eclipse.org/forums/index.php?t=msg&goto=643163&S=d54f595421f35c4c41d63230d5568001#msg_643163 and also a sample implementation that could be included into GMF is proposed.

Reproducible: Always

Steps to Reproduce:
1. Draw a link between two nodes
2. Three elements (2 links 1 node in the middle) are generated
