So when you mix and match elements and attributes, I
guess the ordering of these elements and attributes in
the selector field of 'key' and 'keyref' is what is
used in mapping from 'key' fields to 'keyref' fields
(when we have mix of elements and attributes with
matching data types).

is there a brief documentation pointer on this
subject?
