- give the angleFromNetElement and angleToNetElement (in which case, making the angle a subelement instead of an attribute would make more sense to me, as multiple angles could be given)
We think that this would be sufficient for narrowing it down to one layout. It would also be easy to generate and read this data for us.
Defining several angles can be possbile, but is not necessary. It also does not matter which angle is defined.
