Cross-origin extensions can still be handled with full URIs for the
extension properties.

I dont see how you can solve the itemtype="foo" collision case for multiple
itemtypes without some explicit statement about the authority who says what
the combined vocabulary for a set of itemtypes means.

How does "kind" relate to "type"?   Would it be the case that kind informs
the short itemprop names also?
Is this the same proposal as having an itemprop="type" which means the same
thing as itemtype?
