--- yes, the example on the wiki which xFolk was derived has a date
(which was not used for some reason). Ma.gnolia, del.icio.us, any
linkroll in a blog post, de.lirio.us, and technorati (in the form of
... posted 23 days ago), scuttle, all use dates. These were mentioned
in Bud's original schema post
where he extracted the implied schema. Date was not part of that
implied schema for some reason... which lead me to my next question.

It seems to me that Date-time IS part of the implied schema - i was
not part of these original discussions so maybe someone had a very
good argument NOT to keep this in.

i completely agree, but of the examples cited, more than 80% seem to
have some sort of date stamp.
Using your suggestion of nesting an hReview would help add semantics
such as 'dtreviewed', but this doesn't seem to help if i am building a
simple relational database that maps to xFolk. If my parser is
'stupid' and only looking for instances of xFolk and xFolk properties
it doesn't matter what microformats are embedded inside it is
oblivious to them. Once things are aggregated and removed from their
original context we loose the surrounding semantics.
