What are the actual (as opposed to supposedly "common knowledge")  
contemporary use cases for a namespacing mechanism (in light of  
current discussion, as needed in HTML)? My informal research shows  
that the use cases used in introductory materials to explain XML  
namespaces are normally very contrived.

Perhaps it's time to come up with a new list?
