Andy, I'm not sure which evidence you are referring to.  All I noticed was a
a sum of google search results.  We've previously discussed using search
engine hits as evidence.  Can you reiterate which URIs were surveyed along
with an analysis of the markup used?  It would go a long way towards providing
evidence for this feature.  How are people currently publishing dates of
death?  Who is doing it? Are there common authorship patterns?

I'm not sure the lack of negation or an objection is a good reason to decide
on property names chosen without evidence.
