Yes, initially I used the node IDs which caused problems, but after Emil 
told me that this was not good, I decided to follow the instructions in 
<http://verse.blender.org/cms/Multiple_Materials.674.0.html>. Apparently,
my explanation, cited above, was unclear, because this is what I was 
referring to. By using the expression "material numbers" I did not mean 
the material node IDs, but the link tag approach, which is evident if you 
read the whole text I wrote.
