Yes, it seems fraught with bogus restrictions, which makes me wonder if
we're interpreting it correctly.
I could understand a definition that says "unqualified names are first
sought as output column names, and if no match then treated as input
column names; qualified names are always input column names". Perhaps
that's what they're really trying to do, but why all the strange
verbiage?
