I apologize - this is for some proposed future version of RDFa (e.g. 
RDFa Syntax 1.1)  I had an action item from ages ago to write up the 
exact text so we could consider it concretely instead of in the 
abstract.  The original idea came from Mark Birbeck (thanks Mark!)

This is a good point - we have discussed it in the past.  Announcement 
and behavior when announcement is not used is something that we would 
need to lock down.  I imagine there will be other features of some 
future RDFa 1.1 that would also turn on or off depending on such an 
announcement.  That whole topic is separate from this one change.
