/* note: at first it seemed that this would be a good place to trap
* as an error an attempt to set a version # for a class which doesn't
* save its class information (including version #) in the archive.
* However, this imposes a requirement that the version be set after
* the implemention level which would be pretty confusing. If this
* is to be done, do this check in the input or output operators when
* ALL the serialization traits are available. Included the implementation
* here with this comment as a reminder not to do this!
