cwm allows more datatypes in N3 than in RDF/XML

Message-Id: <1155222147.30621.544.camel@dirk.w3.org>

cwm reads this in...

<http://dig.csail.mit.edu/TAMI/2006/07/s3#arrest-1>
<http://dig.csail.mit.edu/TAMI/cph/v2/deduce#arrest-item-justified>
"false"^^<xsd:Boolean> .

and writes this out...

 <ded:arrest-item-justified rdf:datatype="xsd:Boolean">

but then when you try to read that back in, cwm complains
that there's no # in the datatype URI...
