We haven't defined our requirements on cataloging former versions, because
no one ever thought about it. Of course the documents have to be accessible
thru the catalog in some way. But I can see arguments in favor
(completeness) and against (redundancy) cataloging of entire contents.
Perhaps there should be some simple way to override the searchable_text (or
whatever it's called) method for former versions.

That would be a workflow issue. See below.

Chain of links back to former discussions? I don't know.

What? You must not have meant the former version object will not be
deletable. There must be some way to delete it explicitly (under workflow
perhaps).

>From a requirements view: Yes. In our environment, former versions should
not be modified unless there is some powerful overriding need. That implies
a different workflow. Also the decision to delete, would probably be part of
a different workflow. Whether that's a different Workflow object or a
different branch of the parent Workflow object is an implementation call, I
suppose.

Looking good!
