Bug description:

All methods ending in Valid in IVersionedObject are not methods but invariants.



Almost all its methods are not implemented.



The invariants below are not enforced:

version_count_valid: version_count >= 0

all_version_ids_valid: all_version_ids /= Void and then all_version_ids.count = version_count

all_versions_valid: all_versions /= Void and then all_versions.count = version_count

latest_version_valid: version_count > 0 implies latest_version /= Void



Maybe it would be interesting to have a representation function for this class.
