The subdivision surface nodes has issues interpolating attributes as shown in the video.
The behaviour is different from the subdivision surface modifier.
Also there seems to be a difference between the subdivision of an objects own geometry and the subdivision of external geometry that is referenced in the node tree.

There is still an issue when an instance is used. The issue seems to be that CD_PROP_FLOAT does not have a layerInterp_* function yet. Will add that.
