Rocs - translations issues

[Claus Christensen]

Translating the Rocs interface to Danish, I have run into a couple of 
problems:

Self-edge. Is this the same as a loop (an edge having the same node in 
both ends)?

Spanning Tree Transformation. Is this a transformation of a Spanning 
Tree or a transformation based on a Spanning Tree?

Complete Graph. Am I right in assuming that 'complete' in this context 
is a verb?
