Agreed. Then define it clearly in the specification, which is not the  
case right now. Stress out the differences, gives the general concept  
about namespaces.

As you have written just above:

-moz- is a kind of namespace to "avoid clashes in vendor-specific CSS  
properties and values". This is another mechanism of namespace. It is  
specifically what a namespace is. A mechanism to avoid name clashes  
and create a particular space.

Then it is really necessary to explain the way Namespaces are defined  
in this specification, more than at initially thought.
