you here assume the attribute targetType will be in the result once this method will run. Is it correct?

We assume the presence of the targetType attribute is part of the oaf:relation specification, just like the other attributes. I suppose it is reasonable to assume to know, when defining the transformation rules, the main entity type at which a relationsh will refer to.
