SOCol objects (and subclasses) cannot be shared between classes,
including between a class and its subclass.  But, specifically for
subclasses, *something* has to be shared, because inherited columns will
use the same object to specify the column as the superclass uses.  So
Col (and subclasses) exist as a sort of placeholder, which get turned
into a SOCol object for each class instance.

So yes, you need one of each.  The non-SO* classes all look pretty much
the same.
