Can occurrence transforms include scale/skew?

or can I assume IADOccurrence.WorldTransform() only contains translations and rotations?

I tried scaling a part but it just altered the part itself, not how it fits into the assembly.

I would expect them to only contain translation and rotation because different occurrences of the same part can't have different geometry (other than by using configurations) and scales of parts are handled by IADPartFeatures.AddScaleFeature
