This sounds a lot like the PdbAtomMap and PdbResMap tables in leap. We
can/should make version2 and version3 variants of these, to make it
easier for people to use either type of file.

I don't see that the leading space in v3 is much of a problem,
myself. And what they have is better than v2. I'm not quite sure what
inflexibility in LEaP you are referring to, but Wei seems willing to put
almost any beahvior into sleap, so you should make your needs known.
