Please find attached a version of the core model with Kind split into two separate classes. Was it something like this you were looking for?
To me it makes sense to do the split. Before we had the abstraction between Category and Kind it was tempting to stuff all functionality into the Category. I do not think it is anymore.
I think this, exactly as you say Michael, definitely help clear things up a bit :)
If there are any objections I need them asap, if this is going in I need to start updating the core doc tomorrow. And if anyone has a better name than "Mixin" please speak up!
regards, Ralf

I see that the core UML model has been updated, interesting changes. The name
changes look okay to me (Entity, Kind).
2-cents: Structural and Non-Structural concept might be confusing to folks
reading it the first time through. Perhaps its purpose (extensibility) could be
stated before their definitions in a non normative manner. Lastly, would adding
two subclass of kind (structured/unstructured) help clear things a bit? (The
text seems to speak as if there are two subclasses).
