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.

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.
