This type is not very helpful. It would be good if we could be more precise,
saying either kSmiCid or kMintCid. If you can't, then use kDynamicCid.

[Florian Schneider, 2012/10/02 11:10:31]

Done. If we don't know anything about the range of the value, it can be either
smi or mint.

ditto. We should use only non-abstract class class-ids here. 

[Florian Schneider, 2012/10/02 11:10:31]

Done.
