The named item is sought first in
metadata

it is not present in the metadata
slot, then a partial-name
match is sought in the data
slot. Failing both
tests, an exact-name match is sought in a field named
dataNamesOriginal
in the object's metadata
slot, if that field exists. Failing that, NULL
is returned.
To get information on the specialized variants of this function,
type e.g. ?"[[,adv-method"
