K3 Sets are translated to EOperations when generating the language runtime

[ebousse]

Hello :)

I have an Ecore file with an EClass Transformation, and I used K3 to define an aspect that look like this:

@Aspect(className=Transformation)
class TransformationAspect {
    public val Set<EObject> inputModel = new HashSet;
    ...

When I use Melange to generate the language runtime, the output look like that:

The result is an EOperation inputModel. would it be possible instead to have a EReference with upperBound=-1, ordered=false and unique=true?
