Untrue. An or function, for instance, is supposed to go through a list of
inputs until it finds a true value. If one of those inputs fails to find any
values, and the MustBePresent attribute is false, then an empty bag is
returned. This is done precisely so that the function may skip over that
input and continue on (whereas it might choose to do something different in
an error case). Functions that do not take attribute bags as arguments may
still need to recognize the special case of an empty bag.
