It's not ambiguous unless for some reason you wanted to support doing
both of those things at the same time, but I'm having a hard time
coming up with a realistic use case for that. Still, I think we
probably do want to at least leave the door open to do both things at
different times. For the XMLELEMENT-type case, "value AS label" seems
far superior to "label: value", so if you're going to pick one syntax
for both things, it should be that one.
Alternatively, using "label: value" for identifying which parameter is
intended to get the value and "value AS label" for relabelling seems
OK too, though your argument about standards-compliance is a valid
one.
