Marcos,

I have changed that to:

 Face and kernel are 3D equivalents of boundary and centroid, but there
-is no support (yet) for 3D topology (volumes). The only current use of
-face is possibility to display vertical planes in NVIZ.
+is no support (yet) for 3D topology (volumes). Faces are used in a
+couple of modules including NVIZ to visualize 3D buildings and other
+volumetric figures.

More text is obviously desired...
