Yes and no..  The idea is that QofChoice is a template type..  So
a GNC_ID_OWNER would be QofChoice<Customer,Vendor,Employee,Job>.  You
really can't say that it returns a QOF_TYPE_CHOICE because you need to
know what QofChoice template instance is returned.

These params are used EXTENSIVELY throughout GnuCash.. It's the primary
method for performing queries on objects, and there are lots of assumptions
on the object interactions.
