Re: Schema.org and nested items

I'd love for there to be more discussion on this; the G+ docs were written
as they were at my direction.

If a page is fundamentally about a single entity, defining the item at page
scope makes that fact unambiguous.

Defining the item at html level allows properties to be defined either in
the head or the body (some in one, others in another), which can be handy
when a site already uses e.g. OGP but has more specific information already
in the body.

Sorry, I can't explain why there is both Person and ProfilePage. I hope we
won't have LocalBusinessPage, RestaurantPage, etc. :-)
