Dear All,

is it possible in X3D to store NURBS patches with vertex colours?

The program I am evaluating X3D export for, Asymptote, deals with
Bezier patches, with colours assigned to corners and interpolated
within the patch.
My reading of the format description suggests that the answer is
negative, but the following example from the X3D specification and a
demo of an obsolete viewer suggest otherwise (in both cases I was
unable to find relevant x3d file).
