The key question is whether there exists a format which is likely to be sufficiently stable that we won't have to revisit this decision in another 35 years. All the proposed formats - including PDF, XML, etc. - are moving targets at this time.
That's why I suggested GIF. Like ASCII, GIF has its shortcomings, but its definition hasn't changed in 16 years and I've never seen GIF software that doesn't interoperate.
