It depends how Blueberry is signaled.  If they change the
XML declaration to say 

<?xml version="1.0.1" ?> 

or some such, then the processor has wiggle room.  I have no
idea what the installed base of processors do in this case.

On the other hand, if they do something like

<?xml version="1.0" unicode="3.1.1" ?>

Then every XML processor in the world will correctly reject it.
Of course this second option is not viable if the W3C misguidedly 
lets NEL into the S production.  I must say it feels like a 
really clean use-unicode-by-reference approach. -Tim
