Could you not add the last active date as a qualifier to the somevalue
death date?

In general uncertainty in dates are not so easily entered. Born 1969 or
1970 cannot be entered as 1969 with uncertainty decade since that becomes
1960s (at least that is what is shown to readers) so the only legit way of
entering it is 20th century (bringing the uncertainty from 2 to 100 years).

In general being able to model dates as between X and Y (as for numbers)
would be nice.

Um.. sorry for the sidetrack from somevalue which sidetracked from the
novalue discussion.
