Perhaps an non-formal intro text in Core would solve this. We could put  
some more context behind the core model, why it exist etc, without going  
into the specifics. Any objections?

Regarding structural/non-structural Kind the Kind type does not gain the  
structural/non-structural property until it is instantiated. The Core doc  
says in a few places that "a structural Kind" is an _instance_ of Kind  
etc. However, it can indeed still be quite confusing.

Splitting Kind into two classes each inheriting Category might be a  
solution. That would automatically solve the issue that a non-structural  
Kind MUST NOT be related to a structural Kind. I'll see if I can draw up a  
UML example. Anyone else with an opinion on this?
