Re: Barcodes missing checksum digit

I would be inclined to add two release events, one with each EAN, and add an
annotation explaining the issue. This is what I do in the case of a disc
that has more than one catalogue number printed right on its surface, or is
a disc in a boxed set, with one number on the outside packaging of the box,
and another number on the surface of the individual disc.
