[Auscope-geosciml] Event type vocabulary? what is it

Yikes-- We added Classifier on event as well. That would be the logical 
place to have association of an event with a specific geologic event 
that might be reused (like Hercynian Orogeny, K-T boundary impact) and 
have its own GeologicEvent prototype description.
So what use does that leave for EventType. The only one I can see that 
doesn't create confusion with eventProcess -  eventEnvironment is to use 
it in the sense of GeologicUnitType as a category that specifies 
variations in the content model/intention of the actual GeologicEvent 
element ('type' in the sense of data type). Examples --extended event 
(orogeny), instantaneous event (bolide impact, volcanic eruption). Maybe 
some coherent abstraction of the eventProcess vocabulary could be made 
to categorize events that have different kinds of prototype 
descriptions, but the danger is that if the eventTypes are just the 
broader categories from the eventProcess vocabulary, then its unclear 
which property to filter for those categories -- eventProcess or eventType.
