I looked at the XML of a local project (Greek names),
to see how I dealt with this last year, and found that
we recorded these uncertain dates by giving a textual
version, and a separate @notAfter and @notBefore, which
are used for sorting and retrieval. See samples below.

The users in this domain can easily understand what is meant
by "imp.", "101-60 B.C .", or "f.iii B.C." and the uncertanties
therein, but the poor old computer gets a clue
in can use for ordering. It is not clear to me that the users
would distinguish between a search for "definitely 2nd century names"
and "names which might be 2nd century"; I suspect they'd
retrieve 2nd century names and eyeball the result.

Just to show that there are various ways of dealing with this
problem.
