I think you mean no longer _any_ non-prefixed CURIEs.

How loudly can I say "ewwwww" ?

I really really don't want the default @xmlns namespace to influence how 
CURIEs are transformed.  It would mean that any give CURIE could resolve 
to a different URI just by dragging it to some other segment of a 
document.  It would potentially break the whole drag-and-drop model that 
some people think is the future of the web (not me, you understand.  I 
think it is nonsense).

I would rather just get rid of the empty prefix in the XHTML+RDFa host 
language.  We don't need it for anything.  And if we permit it, and let 
it mutate throughout the document, it would mean that it would be that 
much harder to support an HTML 4 or HTML 5 mapping where there is no xmlns.
