[v3.2.0] Why removing the property dct:type from the class cv:Event?

[jimjyang]

I am wondering why removing the property dct:type from the class cv:Event, when both its subclasses cv:LifeEvent and cv:BusinessEvent have dct:type? Which specific rule in the SEMIC Style Guide this potentially will be in conflict with? Is it "forbidden" to inherit a property and recommend usage of a given controlled vocabulary for that property at the subclass level?
