The spec doesn't specify this. If there were a definitive answer, it  
would be step #9 in the processing sequence.

My vote, if this were to be written up as an errata, would be to  
specify that if @datatype is non-empty but does not contain a valid  
CURIE, to treat it as datatype="" - i.e. the value of the attribute  
is ignored but the presence of the attribute is not ignored. This  
would be consistent with non-CURIE rel, rev, typeof, etc.
