Hi Patrick,

I htink that we are all very busy. I was able to catch Lars Marius on the 
IRC chat for topic maps.

Here is a little of the discussion on namespaces.

The attribute information item in the XML Infoset has the [namespace name] 
property, and since the SAM and XML inforset are based on the same 
metamodel, it would be good to clarify that this is not the "namespace"in 
topic maps.

Any other opinions?
