I found the examples and it seems that the idea is to not do 
collaborative tagging but actually add the tags in the documents with 
class definitions.

This is actually what I and then some others started to do in Web 
Accessibility. For instance, to have images and corresponding captions 
marked with class="figure" and caption with class="caption". The idea is 
that if more people use the same classes it is easier to find certain 
parts of the documents with screenreaders and by other tools benefitting 
from the structure.

Unfortunately we cannot rely on people always using the "figure" for the 
image. To make this work better in the Semantic Web would be to attach a 
URI that describes the "figure" class by using Semantic Web metadata. 
Then it would not matter so much what class names were used. Maybe we 
could use the embedded RDF for this?
