If I remember correctly our topology examples we usually used links 
containing ports/port references (shortly speaking). But our discussion 
with NSI showed that their aproach is different. The NSI topology is 
based on STPs/ports (using connectedTo). Switching from OWL into NML 
does not has to force NSI to change that approach. Use of  Ports with 
isSink/isSource could be more intuitive for NSI.
