I suppose that if you were to pass an empty string into the program and
then attempted to transition to the result it should be the same as
doing:
TransitionTo(("" 0)).
This is legal MHEG and would succeed in a profile that has some
understanding of "", however this would definately fail in the UK
profile because the mapping to the object carousel would fail, the same
as entering any other incorect group identifier.
