Why No Abstract on SimplyType?

The Abstract attribute may be used on the ComplexType element. But it cannot
be used on the SimpleType element. Why?

I had thought it might be to reinforce a rule that abstract types cannot be
based on concrete types, yet this is actually possible with complex types.
