Brian, based on what real world link tagging examples do you think there
should be a date in xFolk?

Other way around.  

We don't need any reason to leave off anything.  Things are left out by

There needs to be a good justification to put things in, starting with being
part of the 80/20 implied schema of existing use in real world examples
published on the *Web*.

Just use hReview to "review" the URL.  hReview has dtreviewed and reviewer
to handle both of these.

Keep xFolk simple as intended.  Note that you can overlap and include both
xFolk and hReview semantics if you wish on tagged URLs.
