Again, an ID is a specific reference which doesn't need to be nested
inside another one. It's never occured to me to use IDs with an "object
of object" syntax so I never ran into the problem, but apparently the
parser doesn't like it.
All you need is: exists(bg id xxx). IDs can't refer to more than one
object and (apparently) references to them won't nest.
